review of literature for phd thesis

• A Guide to Writing a PhD Literature Review

Written by Ben Taylor

Most PhD projects begin with a literature review, which usually serves as the first chapter of your dissertation. This provides an opportunity for you to show that you understand the body of academic work that has already been done in relation to your topic, including books, articles, data and research papers.

You should be prepared to offer your own critical analysis of this literature, as well as illustrating where your own research lies within the field – and how it contributes something new / significant to your subject.

This page will give you an overview of what you need to know about writing a literature review, with detail on structure, length and conclusions.

What is a phd literature review.

A literature review is usually one of the first things you’ll do after beginning your PhD . Once you’ve met with your supervisor and discussed the scope of your research project, you’ll conduct a survey of the scholarly work that’s already been done in your area.

Depending on the nature of your PhD, this work could comprise books, publications, articles, experimental data and more. This body of work is collectively known as the ‘scholarly literature’, on your subject. You won’t have to tackle any novels, poetry or drama during this review (unless, of course, you’re actually studying a PhD in English Literature, in which case that comes later).

The purpose of the PhD literature review isn’t just to summarise what other scholars have done before you. You should analyse and evaluate the current body of work , situating your own research within that context and demonstrating the significant original contribution your research will make.

Planning your PhD literature review

Your supervisor will be able to give you advice if you’re not quite sure where to begin your review, pointing you in the direction of key texts and research that you can then investigate. It’s worth paying attention to the bibliographies (and literature reviews!) of these publications, which can often lead you towards even more specialist texts that could prove invaluable in your research. At the same time, it’s important not to let yourself fall down an academic rabbit hole – make sure that the books and articles you’re surveying are genuinely relevant to your own project.

You should aim to include a broad range of literature in your review, showing the scope of your knowledge, from foundational texts to the most recent publications.

The note-taking process is crucial while you’re in the early stages of your literature review. Keep a clear record of the sources you’ve read, along with your critical analysis of their key arguments and what you think makes them relevant to your research project.

How long should a literature review be?

The length of a PhD literature review varies greatly by subject. In Arts, Humanities and Social Sciences the review will typically be around 5,000 words long, while STEM literature reviews will usually be closer to 10,000 words long. In any case, you should consult with your supervisor on the optimum length for your own literature review.

Structuring a PhD literature review

When you begin to write your PhD literature review, it’s important to have a clear idea of its outline. Roughly speaking, the literature review structure should:

• Introduce your topic and explain its significance
• Evaluate the existing literature with reference to your thesis
• Give a conclusion that considers the implications of your research for future study

The main body of your literature review will be spent critiquing the existing work that scholars have done in your field. There are a few different ways you may want to structure this part of the review, depending on the subject and the nature of your dissertation:

• Chronologically – If your research looks at how something has changed over time, it may make sense to review the literature chronologically, tracking the way that ideas, attitudes and theories have shifted. This might seem like quite a simple way to structure the review, but it’s also imperative to identify the common threads and sticking points between academics along the way, rather than merely reeling off a list of books and articles.
• Thematically – If your dissertation encompasses several different themes, you might want to group the literature by these subjects, while also emphasising the connections between them.
• Methodologically – If you are going to be working with experimental data or statistics, it could be a good idea to assess the different methods that previous scholars have used in your field to produce relevant literature.

Whichever technique you use to structure your literature review, you should take care not to simply list different books, articles and research papers without offering your own commentary.

Always highlight the similarities (and differences) between them, giving your analysis of the significance of these relationships, connections and contrasts.

Writing up a PhD literature review

The process of writing a literature review is different to that of writing the bulk of the dissertation itself. The aim at this point isn’t necessarily to illustrate your own original ideas and research – that’s what the dissertation is for – but rather to show the depth of your knowledge of the field and your ability to assess the work of other scholars . It’s also an opportunity for you to indicate exactly how your dissertation will make an original contribution to your subject area.

These are some tips to bear in mind when writing a literature review:

• Avoid paraphrasing – instead, offer your own evaluation of a source and its assertions
• Follow a logical path from one source or theme to the next – don’t make leaps between different books or articles without explaining the connection between them
• Critically analyse the literature – challenge assumptions, assess the validity of argument and write with authority
• Don’t be too broad in your scope – it can be easy to get carried away including every piece of related literature you come across, but it’s also important not to let your review become too sprawling or rambling

The fact that you usually begin your literature review right at the start of a PhD means that it’s likely you’ll come across plenty more relevant books and papers during the course of your research and while writing the dissertation. So, it’s useful to think of this first draft as a work-in-progress that you keep up-to-date as you write your thesis.

Finishing a PhD literature review

As you come to the end of your dissertation, it’s vital to take a close look at your initial literature review and make sure that it’s consistent with the conclusions that you’ve reached. Of course, a lot can change over the course of a PhD so it’s entirely possible that your research led you in a different direction than you imagined at the beginning.

The conclusion of your literature review should summarise the significance of the survey that you’ve just completed, explaining its relevance for the research your dissertation will undertake.

Literature reviews and PhD upgrade exams

The literature review is usually one of the first sections of a PhD to be completed, at least in its draft form. As such, it is often part of the material that you may submit for your PhD upgrade exam . This usually takes place at the end of your first year (though not all PhDs require it). Involves you discussing your work so far with academics in your department to confirm that your project is on track for a PhD. The feedback you get at this point may help shape your literature review, or reveal any areas you’ve missed.

What is a literature review? A literature review is a survey of scholarly sources on a specific topic. It provides an overview of current knowledge, allowing you to identify relevant theories, methods, and gaps in the existing research that you can later apply to your paper, thesis, or dissertation topic .

There are five key steps to writing a literature review:

• Search for relevant literature
• Evaluate sources
• Identify themes, debates, and gaps
• Outline the structure
• Write your literature review

A good literature review doesn’t just summarize sources—it analyzes, synthesizes , and critically evaluates to give a clear picture of the state of knowledge on the subject.

• Quick Run-through
• Step 1 & 2

When you write a thesis , dissertation , or research paper , you will likely have to conduct a literature review to situate your research within existing knowledge. The literature review gives you a chance to:

• Demonstrate your familiarity with the topic and its scholarly context
• Develop a theoretical framework and methodology for your research
• Position your work in relation to other researchers and theorists
• Show how your research addresses a gap or contributes to a debate
• Evaluate the current state of research and demonstrate your knowledge of the scholarly debates around your topic.

Writing literature reviews is a particularly important skill if you want to apply for graduate school or pursue a career in research. We’ve written a step-by-step guide that you can follow below.

Writing literature reviews can be quite challenging! A good starting point could be to look at some examples, depending on what kind of literature review you’d like to write.

• Example literature review #1: “Why Do People Migrate? A Review of the Theoretical Literature” ( Theoretical literature review about the development of economic migration theory from the 1950s to today.)
• Example literature review #2: “Literature review as a research methodology: An overview and guidelines” ( Methodological literature review about interdisciplinary knowledge acquisition and production.)
• Example literature review #3: “The Use of Technology in English Language Learning: A Literature Review” ( Thematic literature review about the effects of technology on language acquisition.)
• Example literature review #4: “Learners’ Listening Comprehension Difficulties in English Language Learning: A Literature Review” ( Chronological literature review about how the concept of listening skills has changed over time.)

Before you begin searching for literature, you need a clearly defined topic .

If you are writing the literature review section of a dissertation or research paper, you will search for literature related to your research problem and questions .

Make a list of keywords

Start by creating a list of keywords related to your research question. Include each of the key concepts or variables you’re interested in, and list any synonyms and related terms. You can add to this list as you discover new keywords in the process of your literature search.

• Social media, Facebook, Instagram, Twitter, Snapchat, TikTok
• Body image, self-perception, self-esteem, mental health
• Generation Z, teenagers, adolescents, youth

Search for relevant sources

Use your keywords to begin searching for sources. Some useful databases to search for journals and articles include:

• Your university’s library catalogue
• Google Scholar
• Project Muse (humanities and social sciences)
• Medline (life sciences and biomedicine)
• EconLit (economics)
• Inspec (physics, engineering and computer science)

You can also use boolean operators to help narrow down your search.

Make sure to read the abstract to find out whether an article is relevant to your question. When you find a useful book or article, you can check the bibliography to find other relevant sources.

You likely won’t be able to read absolutely everything that has been written on your topic, so it will be necessary to evaluate which sources are most relevant to your research question.

For each publication, ask yourself:

• What question or problem is the author addressing?
• What are the key concepts and how are they defined?
• What are the key theories, models, and methods?
• Does the research use established frameworks or take an innovative approach?
• What are the results and conclusions of the study?
• How does the publication relate to other literature in the field? Does it confirm, add to, or challenge established knowledge?
• What are the strengths and weaknesses of the research?

Make sure the sources you use are credible , and make sure you read any landmark studies and major theories in your field of research.

You can use our template to summarize and evaluate sources you’re thinking about using. Click on either button below to download.

Take notes and cite your sources

As you read, you should also begin the writing process. Take notes that you can later incorporate into the text of your literature review.

It is important to keep track of your sources with citations to avoid plagiarism . It can be helpful to make an annotated bibliography , where you compile full citation information and write a paragraph of summary and analysis for each source. This helps you remember what you read and saves time later in the process.

Receive feedback on language, structure, and formatting

Professional editors proofread and edit your paper by focusing on:

• Academic style
• Vague sentences
• Style consistency

See an example

To begin organizing your literature review’s argument and structure, be sure you understand the connections and relationships between the sources you’ve read. Based on your reading and notes, you can look for:

• Trends and patterns (in theory, method or results): do certain approaches become more or less popular over time?
• Themes: what questions or concepts recur across the literature?
• Debates, conflicts and contradictions: where do sources disagree?
• Pivotal publications: are there any influential theories or studies that changed the direction of the field?
• Gaps: what is missing from the literature? Are there weaknesses that need to be addressed?

This step will help you work out the structure of your literature review and (if applicable) show how your own research will contribute to existing knowledge.

• Most research has focused on young women.
• There is an increasing interest in the visual aspects of social media.
• But there is still a lack of robust research on highly visual platforms like Instagram and Snapchat—this is a gap that you could address in your own research.

There are various approaches to organizing the body of a literature review. Depending on the length of your literature review, you can combine several of these strategies (for example, your overall structure might be thematic, but each theme is discussed chronologically).

Chronological

The simplest approach is to trace the development of the topic over time. However, if you choose this strategy, be careful to avoid simply listing and summarizing sources in order.

Try to analyze patterns, turning points and key debates that have shaped the direction of the field. Give your interpretation of how and why certain developments occurred.

If you have found some recurring central themes, you can organize your literature review into subsections that address different aspects of the topic.

For example, if you are reviewing literature about inequalities in migrant health outcomes, key themes might include healthcare policy, language barriers, cultural attitudes, legal status, and economic access.

Methodological

If you draw your sources from different disciplines or fields that use a variety of research methods , you might want to compare the results and conclusions that emerge from different approaches. For example:

• Look at what results have emerged in qualitative versus quantitative research
• Discuss how the topic has been approached by empirical versus theoretical scholarship
• Divide the literature into sociological, historical, and cultural sources

Theoretical

A literature review is often the foundation for a theoretical framework . You can use it to discuss various theories, models, and definitions of key concepts.

You might argue for the relevance of a specific theoretical approach, or combine various theoretical concepts to create a framework for your research.

Like any other academic text , your literature review should have an introduction , a main body, and a conclusion . What you include in each depends on the objective of your literature review.

The introduction should clearly establish the focus and purpose of the literature review.

Depending on the length of your literature review, you might want to divide the body into subsections. You can use a subheading for each theme, time period, or methodological approach.

As you write, you can follow these tips:

• Summarize and synthesize: give an overview of the main points of each source and combine them into a coherent whole
• Analyze and interpret: don’t just paraphrase other researchers — add your own interpretations where possible, discussing the significance of findings in relation to the literature as a whole
• Critically evaluate: mention the strengths and weaknesses of your sources
• Write in well-structured paragraphs: use transition words and topic sentences to draw connections, comparisons and contrasts

In the conclusion, you should summarize the key findings you have taken from the literature and emphasize their significance.

A literature review is a survey of scholarly sources (such as books, journal articles, and theses) related to a specific topic or research question .

It is often written as part of a thesis, dissertation , or research paper , in order to situate your work in relation to existing knowledge.

There are several reasons to conduct a literature review at the beginning of a research project:

• To familiarize yourself with the current state of knowledge on your topic
• To ensure that you’re not just repeating what others have already done
• To identify gaps in knowledge and unresolved problems that your research can address
• To develop your theoretical framework and methodology
• To provide an overview of the key findings and debates on the topic

Writing the literature review shows your reader how your work relates to existing research and what new insights it will contribute.

The literature review usually comes near the beginning of your thesis or dissertation . After the introduction , it grounds your research in a scholarly field and leads directly to your theoretical framework or methodology .

A literature review is a survey of credible sources on a topic, often used in dissertations , theses, and research papers . Literature reviews give an overview of knowledge on a subject, helping you identify relevant theories and methods, as well as gaps in existing research. Literature reviews are set up similarly to other  academic texts , with an introduction , a main body, and a conclusion .

An  annotated bibliography is a list of  source references that has a short description (called an annotation ) for each of the sources. It is often assigned as part of the research process for a  paper .

• What Is a PhD Literature Review?
• Doing a PhD

A literature review is a critical analysis of published academic literature, mainly peer-reviewed papers and books, on a specific topic. This isn’t just a list of published studies but is a document summarising and critically appraising the main work by researchers in the field, the key findings, limitations and gaps identified in the knowledge.

• The aim of a literature review is to critically assess the literature in your chosen field of research and be able to present an overview of the current knowledge gained from previous work.
• By the conclusion of your literature review, you as a researcher should have identified the gaps in knowledge in your field; i.e. the unanswered research questions which your PhD project will help to answer.
• Quality not quantity is the approach to use when writing a literature review for a PhD but as a general rule of thumb, most are between 6,000 and 12,000 words.

What Is the Purpose of a Literature Review?

First, to be clear on what a PhD literature review is NOT: it is not a ‘paper by paper’ summary of what others have done in your field. All you’re doing here is listing out all the papers and book chapters you’ve found with some text joining things together. This is a common mistake made by PhD students early on in their research project. This is a sign of poor academic writing and if it’s not picked up by your supervisor, it’ll definitely be by your examiners.

The biggest issue your examiners will have here is that you won’t have demonstrated an application of critical thinking when examining existing knowledge from previous research. This is an important part of the research process as a PhD student. It’s needed to show where the gaps in knowledge were, and how then you were able to identify the novelty of each research question and subsequent work.

The five main outcomes from carrying out a good literature review should be:

• An understanding of what has been published in your subject area of research,
• An appreciation of the leading research groups and authors in your field and their key contributions to the research topic,
• Knowledge of the key theories in your field,
• Knowledge of the main research areas within your field of interest,
• A clear understanding of the research gap in knowledge that will help to motivate your PhD research questions .

When assessing the academic papers or books that you’ve come across, you must think about the strengths and weaknesses of them; what was novel about their work and what were the limitations? Are different sources of relevant literature coming to similar conclusions and complementing each other, or are you seeing different outcomes on the same topic by different researchers?

When Should I Write My Literature Review?

In the structure of your PhD thesis , your literature review is effectively your first main chapter. It’s at the start of your thesis and should, therefore, be a task you perform at the start of your research. After all, you need to have reviewed the literature to work out how your research can contribute novel findings to your area of research. Sometimes, however, in particular when you apply for a PhD project with a pre-defined research title and research questions, your supervisor may already know where the gaps in knowledge are.

You may be tempted to skip the literature review and dive straight into tackling the set questions (then completing the review at the end before thesis submission) but we strongly advise against this. Whilst your supervisor will be very familiar with the area, you as a doctoral student will not be and so it is essential that you gain this understanding before getting into the research.

How Long Should the Literature Review Be?

As your literature review will be one of your main thesis chapters, it needs to be a substantial body of work. It’s not a good strategy to have a thesis writing process here based on a specific word count, but know that most reviews are typically between 6,000 and 12,000 words. The length will depend on how much relevant material has previously been published in your field.

A point to remember though is that the review needs to be easy to read and avoid being filled with unnecessary information; in your search of selected literature, consider filtering out publications that don’t appear to add anything novel to the discussion – this might be useful in fields with hundreds of papers.

How Do I Write the Literature Review?

Before you start writing your literature review, you need to be clear on the topic you are researching.

1. Evaluating and Selecting the Publications

After completing your literature search and downloading all the papers you find, you may find that you have a lot of papers to read through ! You may find that you have so many papers that it’s unreasonable to read through all of them in their entirety, so you need to find a way to understand what they’re about and decide if they’re important quickly.

A good starting point is to read the abstract of the paper to gauge if it is useful and, as you do so, consider the following questions in your mind:

• What was the overarching aim of the paper?
• What was the methodology used by the authors?
• Was this an experimental study or was this more theoretical in its approach?
• What were the results and what did the authors conclude in their paper?
• How does the data presented in this paper relate to other publications within this field?
• Does it add new knowledge, does it raise more questions or does it confirm what is already known in your field? What is the key concept that the study described?
• What are the strengths and weaknesses of this study, and in particular, what are the limitations?

2. Identifying Themes

To put together the structure of your literature review you need to identify the common themes that emerge from the collective papers and books that you have read. Key things to think about are:

• Are there common methodologies different authors have used or have these changed over time?
• Do the research questions change over time or are the key question’s still unanswered?
• Is there general agreement between different research groups in the main results and outcomes, or do different authors provide differing points of view and different conclusions?
• What are the key papers in your field that have had the biggest impact on the research?
• Have different publications identified similar weaknesses or limitations or gaps in the knowledge that still need to be addressed?

Structuring and Writing Your Literature Review

There are several ways in which you can structure a literature review and this may depend on if, for example, your project is a science or non-science based PhD.

One approach may be to tell a story about how your research area has developed over time. You need to be careful here that you don’t just describe the different papers published in chronological order but that you discuss how different studies have motivated subsequent studies, how the knowledge has developed over time in your field, concluding with what is currently known, and what is currently not understood.

Alternatively, you may find from reading your papers that common themes emerge and it may be easier to develop your review around these, i.e. a thematic review. For example, if you are writing up about bridge design, you may structure the review around the themes of regulation, analysis, and sustainability.

As another approach, you might want to talk about the different research methodologies that have been used. You could then compare and contrast the results and ultimate conclusions that have been drawn from each.

As with all your chapters in your thesis, your literature review will be broken up into three key headings, with the basic structure being the introduction, the main body and conclusion. Within the main body, you will use several subheadings to separate out the topics depending on if you’re structuring it by the time period, the methods used or the common themes that have emerged.

The important thing to think about as you write your main body of text is to summarise the key takeaway messages from each research paper and how they come together to give one or more conclusions. Don’t just stop at summarising the papers though, instead continue on to give your analysis and your opinion on how these previous publications fit into the wider research field and where they have an impact. Emphasise the strengths of the studies you have evaluated also be clear on the limitations of previous work how these may have influenced the results and conclusions of the studies.

In your concluding paragraphs focus your discussion on how your critical evaluation of literature has helped you identify unanswered research questions and how you plan to address these in your PhD project. State the research problem you’re going to address and end with the overarching aim and key objectives of your work .

When writing at a graduate level, you have to take a critical approach when reading existing literature in your field to determine if and how it added value to existing knowledge. You may find that a large number of the papers on your reference list have the right academic context but are essentially saying the same thing. As a graduate student, you’ll need to take a methodological approach to work through this existing research to identify what is relevant literature and what is not.

You then need to go one step further to interpret and articulate the current state of what is known, based on existing theories, and where the research gaps are. It is these gaps in the literature that you will address in your own research project.

• Decide on a research area and an associated research question.
• Decide on the extent of your scope and start looking for literature.
• Review and evaluate the literature.
• Plan an outline for your literature review and start writing it.

How to write a superb literature review

Andy Tay is a freelance writer based in Singapore.

You can also search for this author in PubMed   Google Scholar

Literature reviews are important resources for scientists. They provide historical context for a field while offering opinions on its future trajectory. Creating them can provide inspiration for one’s own research, as well as some practice in writing. But few scientists are trained in how to write a review — or in what constitutes an excellent one. Even picking the appropriate software to use can be an involved decision (see ‘Tools and techniques’). So Nature asked editors and working scientists with well-cited reviews for their tips.

Writing a Literature Review

Welcome to the Purdue OWL

This page is brought to you by the OWL at Purdue University. When printing this page, you must include the entire legal notice.

A literature review is a document or section of a document that collects key sources on a topic and discusses those sources in conversation with each other (also called synthesis ). The lit review is an important genre in many disciplines, not just literature (i.e., the study of works of literature such as novels and plays). When we say “literature review” or refer to “the literature,” we are talking about the research ( scholarship ) in a given field. You will often see the terms “the research,” “the scholarship,” and “the literature” used mostly interchangeably.

Where, when, and why would I write a lit review?

There are a number of different situations where you might write a literature review, each with slightly different expectations; different disciplines, too, have field-specific expectations for what a literature review is and does. For instance, in the humanities, authors might include more overt argumentation and interpretation of source material in their literature reviews, whereas in the sciences, authors are more likely to report study designs and results in their literature reviews; these differences reflect these disciplines’ purposes and conventions in scholarship. You should always look at examples from your own discipline and talk to professors or mentors in your field to be sure you understand your discipline’s conventions, for literature reviews as well as for any other genre.

A literature review can be a part of a research paper or scholarly article, usually falling after the introduction and before the research methods sections. In these cases, the lit review just needs to cover scholarship that is important to the issue you are writing about; sometimes it will also cover key sources that informed your research methodology.

Lit reviews can also be standalone pieces, either as assignments in a class or as publications. In a class, a lit review may be assigned to help students familiarize themselves with a topic and with scholarship in their field, get an idea of the other researchers working on the topic they’re interested in, find gaps in existing research in order to propose new projects, and/or develop a theoretical framework and methodology for later research. As a publication, a lit review usually is meant to help make other scholars’ lives easier by collecting and summarizing, synthesizing, and analyzing existing research on a topic. This can be especially helpful for students or scholars getting into a new research area, or for directing an entire community of scholars toward questions that have not yet been answered.

What are the parts of a lit review?

Most lit reviews use a basic introduction-body-conclusion structure; if your lit review is part of a larger paper, the introduction and conclusion pieces may be just a few sentences while you focus most of your attention on the body. If your lit review is a standalone piece, the introduction and conclusion take up more space and give you a place to discuss your goals, research methods, and conclusions separately from where you discuss the literature itself.

Introduction:

• An introductory paragraph that explains what your working topic and thesis is
• A forecast of key topics or texts that will appear in the review
• Potentially, a description of how you found sources and how you analyzed them for inclusion and discussion in the review (more often found in published, standalone literature reviews than in lit review sections in an article or research paper)
• Summarize and synthesize: Give an overview of the main points of each source and combine them into a coherent whole
• Analyze and interpret: Don’t just paraphrase other researchers – add your own interpretations where possible, discussing the significance of findings in relation to the literature as a whole
• Critically Evaluate: Mention the strengths and weaknesses of your sources
• Write in well-structured paragraphs: Use transition words and topic sentence to draw connections, comparisons, and contrasts.

Conclusion:

• Summarize the key findings you have taken from the literature and emphasize their significance
• Connect it back to your primary research question

How should I organize my lit review?

Lit reviews can take many different organizational patterns depending on what you are trying to accomplish with the review. Here are some examples:

• Chronological : The simplest approach is to trace the development of the topic over time, which helps familiarize the audience with the topic (for instance if you are introducing something that is not commonly known in your field). If you choose this strategy, be careful to avoid simply listing and summarizing sources in order. Try to analyze the patterns, turning points, and key debates that have shaped the direction of the field. Give your interpretation of how and why certain developments occurred (as mentioned previously, this may not be appropriate in your discipline — check with a teacher or mentor if you’re unsure).
• Thematic : If you have found some recurring central themes that you will continue working with throughout your piece, you can organize your literature review into subsections that address different aspects of the topic. For example, if you are reviewing literature about women and religion, key themes can include the role of women in churches and the religious attitude towards women.
• Qualitative versus quantitative research
• Empirical versus theoretical scholarship
• Divide the research by sociological, historical, or cultural sources
• Theoretical : In many humanities articles, the literature review is the foundation for the theoretical framework. You can use it to discuss various theories, models, and definitions of key concepts. You can argue for the relevance of a specific theoretical approach or combine various theorical concepts to create a framework for your research.

What are some strategies or tips I can use while writing my lit review?

Any lit review is only as good as the research it discusses; make sure your sources are well-chosen and your research is thorough. Don’t be afraid to do more research if you discover a new thread as you’re writing. More info on the research process is available in our "Conducting Research" resources .

As you’re doing your research, create an annotated bibliography ( see our page on the this type of document ). Much of the information used in an annotated bibliography can be used also in a literature review, so you’ll be not only partially drafting your lit review as you research, but also developing your sense of the larger conversation going on among scholars, professionals, and any other stakeholders in your topic.

Usually you will need to synthesize research rather than just summarizing it. This means drawing connections between sources to create a picture of the scholarly conversation on a topic over time. Many student writers struggle to synthesize because they feel they don’t have anything to add to the scholars they are citing; here are some strategies to help you:

• It often helps to remember that the point of these kinds of syntheses is to show your readers how you understand your research, to help them read the rest of your paper.
• Writing teachers often say synthesis is like hosting a dinner party: imagine all your sources are together in a room, discussing your topic. What are they saying to each other?
• Look at the in-text citations in each paragraph. Are you citing just one source for each paragraph? This usually indicates summary only. When you have multiple sources cited in a paragraph, you are more likely to be synthesizing them (not always, but often
• Read more about synthesis here.

The most interesting literature reviews are often written as arguments (again, as mentioned at the beginning of the page, this is discipline-specific and doesn’t work for all situations). Often, the literature review is where you can establish your research as filling a particular gap or as relevant in a particular way. You have some chance to do this in your introduction in an article, but the literature review section gives a more extended opportunity to establish the conversation in the way you would like your readers to see it. You can choose the intellectual lineage you would like to be part of and whose definitions matter most to your thinking (mostly humanities-specific, but this goes for sciences as well). In addressing these points, you argue for your place in the conversation, which tends to make the lit review more compelling than a simple reporting of other sources.

Ten Simple Rules for Writing a Literature Review

Marco pautasso.

1 Centre for Functional and Evolutionary Ecology (CEFE), CNRS, Montpellier, France

2 Centre for Biodiversity Synthesis and Analysis (CESAB), FRB, Aix-en-Provence, France

Literature reviews are in great demand in most scientific fields. Their need stems from the ever-increasing output of scientific publications [1] . For example, compared to 1991, in 2008 three, eight, and forty times more papers were indexed in Web of Science on malaria, obesity, and biodiversity, respectively [2] . Given such mountains of papers, scientists cannot be expected to examine in detail every single new paper relevant to their interests [3] . Thus, it is both advantageous and necessary to rely on regular summaries of the recent literature. Although recognition for scientists mainly comes from primary research, timely literature reviews can lead to new synthetic insights and are often widely read [4] . For such summaries to be useful, however, they need to be compiled in a professional way [5] .

When starting from scratch, reviewing the literature can require a titanic amount of work. That is why researchers who have spent their career working on a certain research issue are in a perfect position to review that literature. Some graduate schools are now offering courses in reviewing the literature, given that most research students start their project by producing an overview of what has already been done on their research issue [6] . However, it is likely that most scientists have not thought in detail about how to approach and carry out a literature review.

Reviewing the literature requires the ability to juggle multiple tasks, from finding and evaluating relevant material to synthesising information from various sources, from critical thinking to paraphrasing, evaluating, and citation skills [7] . In this contribution, I share ten simple rules I learned working on about 25 literature reviews as a PhD and postdoctoral student. Ideas and insights also come from discussions with coauthors and colleagues, as well as feedback from reviewers and editors.

Rule 1: Define a Topic and Audience

How to choose which topic to review? There are so many issues in contemporary science that you could spend a lifetime of attending conferences and reading the literature just pondering what to review. On the one hand, if you take several years to choose, several other people may have had the same idea in the meantime. On the other hand, only a well-considered topic is likely to lead to a brilliant literature review [8] . The topic must at least be:

• interesting to you (ideally, you should have come across a series of recent papers related to your line of work that call for a critical summary),
• an important aspect of the field (so that many readers will be interested in the review and there will be enough material to write it), and
• a well-defined issue (otherwise you could potentially include thousands of publications, which would make the review unhelpful).

Ideas for potential reviews may come from papers providing lists of key research questions to be answered [9] , but also from serendipitous moments during desultory reading and discussions. In addition to choosing your topic, you should also select a target audience. In many cases, the topic (e.g., web services in computational biology) will automatically define an audience (e.g., computational biologists), but that same topic may also be of interest to neighbouring fields (e.g., computer science, biology, etc.).

Rule 2: Search and Re-search the Literature

After having chosen your topic and audience, start by checking the literature and downloading relevant papers. Five pieces of advice here:

• keep track of the search items you use (so that your search can be replicated [10] ),
• keep a list of papers whose pdfs you cannot access immediately (so as to retrieve them later with alternative strategies),
• use a paper management system (e.g., Mendeley, Papers, Qiqqa, Sente),
• define early in the process some criteria for exclusion of irrelevant papers (these criteria can then be described in the review to help define its scope), and
• do not just look for research papers in the area you wish to review, but also seek previous reviews.

The chances are high that someone will already have published a literature review ( Figure 1 ), if not exactly on the issue you are planning to tackle, at least on a related topic. If there are already a few or several reviews of the literature on your issue, my advice is not to give up, but to carry on with your own literature review,

The bottom-right situation (many literature reviews but few research papers) is not just a theoretical situation; it applies, for example, to the study of the impacts of climate change on plant diseases, where there appear to be more literature reviews than research studies [33] .

• discussing in your review the approaches, limitations, and conclusions of past reviews,
• trying to find a new angle that has not been covered adequately in the previous reviews, and
• incorporating new material that has inevitably accumulated since their appearance.

When searching the literature for pertinent papers and reviews, the usual rules apply:

• be thorough,
• use different keywords and database sources (e.g., DBLP, Google Scholar, ISI Proceedings, JSTOR Search, Medline, Scopus, Web of Science), and
• look at who has cited past relevant papers and book chapters.

Rule 3: Take Notes While Reading

If you read the papers first, and only afterwards start writing the review, you will need a very good memory to remember who wrote what, and what your impressions and associations were while reading each single paper. My advice is, while reading, to start writing down interesting pieces of information, insights about how to organize the review, and thoughts on what to write. This way, by the time you have read the literature you selected, you will already have a rough draft of the review.

Of course, this draft will still need much rewriting, restructuring, and rethinking to obtain a text with a coherent argument [11] , but you will have avoided the danger posed by staring at a blank document. Be careful when taking notes to use quotation marks if you are provisionally copying verbatim from the literature. It is advisable then to reformulate such quotes with your own words in the final draft. It is important to be careful in noting the references already at this stage, so as to avoid misattributions. Using referencing software from the very beginning of your endeavour will save you time.

Rule 4: Choose the Type of Review You Wish to Write

After having taken notes while reading the literature, you will have a rough idea of the amount of material available for the review. This is probably a good time to decide whether to go for a mini- or a full review. Some journals are now favouring the publication of rather short reviews focusing on the last few years, with a limit on the number of words and citations. A mini-review is not necessarily a minor review: it may well attract more attention from busy readers, although it will inevitably simplify some issues and leave out some relevant material due to space limitations. A full review will have the advantage of more freedom to cover in detail the complexities of a particular scientific development, but may then be left in the pile of the very important papers “to be read” by readers with little time to spare for major monographs.

There is probably a continuum between mini- and full reviews. The same point applies to the dichotomy of descriptive vs. integrative reviews. While descriptive reviews focus on the methodology, findings, and interpretation of each reviewed study, integrative reviews attempt to find common ideas and concepts from the reviewed material [12] . A similar distinction exists between narrative and systematic reviews: while narrative reviews are qualitative, systematic reviews attempt to test a hypothesis based on the published evidence, which is gathered using a predefined protocol to reduce bias [13] , [14] . When systematic reviews analyse quantitative results in a quantitative way, they become meta-analyses. The choice between different review types will have to be made on a case-by-case basis, depending not just on the nature of the material found and the preferences of the target journal(s), but also on the time available to write the review and the number of coauthors [15] .

Rule 5: Keep the Review Focused, but Make It of Broad Interest

Whether your plan is to write a mini- or a full review, it is good advice to keep it focused 16 , 17 . Including material just for the sake of it can easily lead to reviews that are trying to do too many things at once. The need to keep a review focused can be problematic for interdisciplinary reviews, where the aim is to bridge the gap between fields [18] . If you are writing a review on, for example, how epidemiological approaches are used in modelling the spread of ideas, you may be inclined to include material from both parent fields, epidemiology and the study of cultural diffusion. This may be necessary to some extent, but in this case a focused review would only deal in detail with those studies at the interface between epidemiology and the spread of ideas.

While focus is an important feature of a successful review, this requirement has to be balanced with the need to make the review relevant to a broad audience. This square may be circled by discussing the wider implications of the reviewed topic for other disciplines.

Rule 6: Be Critical and Consistent

Reviewing the literature is not stamp collecting. A good review does not just summarize the literature, but discusses it critically, identifies methodological problems, and points out research gaps [19] . After having read a review of the literature, a reader should have a rough idea of:

• the major achievements in the reviewed field,
• the main areas of debate, and
• the outstanding research questions.

It is challenging to achieve a successful review on all these fronts. A solution can be to involve a set of complementary coauthors: some people are excellent at mapping what has been achieved, some others are very good at identifying dark clouds on the horizon, and some have instead a knack at predicting where solutions are going to come from. If your journal club has exactly this sort of team, then you should definitely write a review of the literature! In addition to critical thinking, a literature review needs consistency, for example in the choice of passive vs. active voice and present vs. past tense.

Rule 7: Find a Logical Structure

Like a well-baked cake, a good review has a number of telling features: it is worth the reader's time, timely, systematic, well written, focused, and critical. It also needs a good structure. With reviews, the usual subdivision of research papers into introduction, methods, results, and discussion does not work or is rarely used. However, a general introduction of the context and, toward the end, a recapitulation of the main points covered and take-home messages make sense also in the case of reviews. For systematic reviews, there is a trend towards including information about how the literature was searched (database, keywords, time limits) [20] .

How can you organize the flow of the main body of the review so that the reader will be drawn into and guided through it? It is generally helpful to draw a conceptual scheme of the review, e.g., with mind-mapping techniques. Such diagrams can help recognize a logical way to order and link the various sections of a review [21] . This is the case not just at the writing stage, but also for readers if the diagram is included in the review as a figure. A careful selection of diagrams and figures relevant to the reviewed topic can be very helpful to structure the text too [22] .

Rule 8: Make Use of Feedback

Reviews of the literature are normally peer-reviewed in the same way as research papers, and rightly so [23] . As a rule, incorporating feedback from reviewers greatly helps improve a review draft. Having read the review with a fresh mind, reviewers may spot inaccuracies, inconsistencies, and ambiguities that had not been noticed by the writers due to rereading the typescript too many times. It is however advisable to reread the draft one more time before submission, as a last-minute correction of typos, leaps, and muddled sentences may enable the reviewers to focus on providing advice on the content rather than the form.

Feedback is vital to writing a good review, and should be sought from a variety of colleagues, so as to obtain a diversity of views on the draft. This may lead in some cases to conflicting views on the merits of the paper, and on how to improve it, but such a situation is better than the absence of feedback. A diversity of feedback perspectives on a literature review can help identify where the consensus view stands in the landscape of the current scientific understanding of an issue [24] .

Rule 9: Include Your Own Relevant Research, but Be Objective

In many cases, reviewers of the literature will have published studies relevant to the review they are writing. This could create a conflict of interest: how can reviewers report objectively on their own work [25] ? Some scientists may be overly enthusiastic about what they have published, and thus risk giving too much importance to their own findings in the review. However, bias could also occur in the other direction: some scientists may be unduly dismissive of their own achievements, so that they will tend to downplay their contribution (if any) to a field when reviewing it.

In general, a review of the literature should neither be a public relations brochure nor an exercise in competitive self-denial. If a reviewer is up to the job of producing a well-organized and methodical review, which flows well and provides a service to the readership, then it should be possible to be objective in reviewing one's own relevant findings. In reviews written by multiple authors, this may be achieved by assigning the review of the results of a coauthor to different coauthors.

Rule 10: Be Up-to-Date, but Do Not Forget Older Studies

Given the progressive acceleration in the publication of scientific papers, today's reviews of the literature need awareness not just of the overall direction and achievements of a field of inquiry, but also of the latest studies, so as not to become out-of-date before they have been published. Ideally, a literature review should not identify as a major research gap an issue that has just been addressed in a series of papers in press (the same applies, of course, to older, overlooked studies (“sleeping beauties” [26] )). This implies that literature reviewers would do well to keep an eye on electronic lists of papers in press, given that it can take months before these appear in scientific databases. Some reviews declare that they have scanned the literature up to a certain point in time, but given that peer review can be a rather lengthy process, a full search for newly appeared literature at the revision stage may be worthwhile. Assessing the contribution of papers that have just appeared is particularly challenging, because there is little perspective with which to gauge their significance and impact on further research and society.

Inevitably, new papers on the reviewed topic (including independently written literature reviews) will appear from all quarters after the review has been published, so that there may soon be the need for an updated review. But this is the nature of science [27] – [32] . I wish everybody good luck with writing a review of the literature.

Overview of thesis (introduction)

This introductory section is less than two pages long.

The first paragraph:

• states the overall objective of the thesis
• defines the introduced term
• provides broad motivation for interest in the area
• introduces the sections of the thesis that will address the overall objective.

The other paragraphs describe the content and purpose of each section of the thesis.

Literature review

The literature review is made of up of two chapters.

Chapter 1: Literature review of relevant research

The overall goals of this chapter are to firstly establish the significance of the general field of study, and then identify a place where a new contribution could be made.

The bulk of the chapter critically evaluates the methodologies used in this field to identify the appropriate approach for investigating the research questions.

Chapter 2: Theoretical explanations of memory conformity

Chapter 5, Study 3: Co-Witness Contamination

This chapter has the following structure:

• Introduction
• Discussion.

The introduction introduces the particular study to be reported on, and includes a three-and-a-half page literature review.

The literature review in this chapter:

• links back to the relevant general findings of the earlier literature review chapters
• briefly reviews the broad motivation for this study
• identifies that two previously used methodologies in this field will be compared to resolve questions about the findings of previous studies which had only used a single methodology
• uses previous literature to generate specific hypotheses to test
• reviews additional literature to provide a justification for a second objective to be investigated in the study reported on in this chapter.

The Literature Review: A Guide for Postgraduate Students

This guide provides postgraduate students with an overview of the literature review required for most research degrees. It will advise you on the common types of literature reviews across disciplines and will outline how the purpose and structure of each may differ slightly. Various approaches to effective content organisation and writing style are offered, along with some common strategies for effective writing and avoiding some common mistakes. This guide focuses mainly on the required elements of a standalone literature review, but the suggestions and advice apply to literature reviews incorporated into other chapters.

Please see the companion article ‘ The Literature Review: A Guide for Undergraduate Students ’ for an introduction to the basic elements of a literature review. This article focuses on aspects that are particular to postgraduate literature reviews, containing detailed advice and effective strategies for writing a successful literature review. It will address the following topics:

• The purpose of a literature review
• The structure of your literature review
• Strategies for writing an effective literature review
• Mistakes to avoid

The Purpose of a Literature Review

After developing your research proposal and writing a research statement, your literature review is one of the most important early tasks you will undertake for your postgraduate research degree. Many faculties and departments require postgraduate research students to write an initial literature review as part of their research proposal, which forms part of the candidature confirmation process that occurs six months into the research degree for full-time students (12 months for part-time students).

For example, a postgraduate student in history would normally write a 10,000-word research proposal—including a literature review—in the first six months of their PhD. This would be assessed in order to confirm the ongoing candidature of the student.

The literature review is your opportunity you show your supervisor (and ultimately, your examiners) that you understand the most important debates in your field, can identify the texts and authors most relevant to your particular topic, and can examine and evaluate these debates and texts both critically and in depth. You will be expected to provide a comprehensive, detailed and relevant range of scholarly works in your literature review.

In general, a literature review has a specific and directed purpose: to focus the reader’s attention on the significance and necessity of your research. By identifying a ‘gap’ in the current scholarship, you convince your readers that your own research is vital.

As the author, you will achieve these objectives by displaying your in-depth knowledge and understanding of the relevant scholarship in your field, situating your own research within this wider body of work , while critically analysing the scholarship and highlighting your own arguments in relation to that scholarship.

A well-focused, well-developed and well-researched literature review operates as a linchpin for your thesis, provides the background to your research and demonstrates your proficiency in some requisite academic skills.

The Structure of Your Literature Review

Postgraduate degrees can be made up of a long thesis (Master’s and PhD by research) or a shorter thesis and coursework (Master’s by coursework; although some Australian universities now require PhD students to undertake coursework in the first year of their degree). Some disciplines involve creative work (such as a novel or artwork) and an exegesis (such as a creative writing research or fine arts degree). Others can comprise a series of published works in the form of a ‘thesis by publication’ (most common in the science and medical fields).

The structure of a literature review will thus vary according to the discipline and the type of thesis. Some of the most common discipline-based variations are outlined in the following paragraphs.

Humanities and Social Science Degrees

Many humanities and social science theses will include a standalone literature review chapter after the introduction and before any methodology (or theoretical approaches) chapters. In these theses, the literature review might make up around 15 to 30 per cent of the total thesis length, reflecting its purpose as a supporting chapter.

Here, the literature review chapter will have an introduction, an appropriate number of discussion paragraphs and a conclusion. As with a research essay, the introduction operates as a ‘road map’ to the chapter. The introduction should outline and clarify the argument you are making in your thesis (Australian National University 2017), as readers will then have a context for the discussion and critical analysis paragraphs that follow.

The main discussion section can be divided further with subheadings, and the material organised in several possible ways: chronologically, thematically or from the better- to the lesser-known issues and arguments. The conclusion should provide a summary of the chapter overall, and should re-state your thesis statement, linking this to the gap you have identified in the literature that confirms the necessity of your research.

For some humanities’ disciplines, such as literature or history (Premaratne 2013, 236–54), where primary sources are central, the literature review may be conducted chapter-by-chapter, with each chapter focusing on one theme and set of scholarly secondary sources relevant to the primary source material.

Science and Mathematics Degrees

For some science or mathematics research degrees, the literature review may be part of the introduction. The relevant literature here may be limited in number and scope, and if the research project is experiment-based, rather than theoretically based, a lengthy critical analysis of past research may be unnecessary (beyond establishing its weaknesses or failings and thus the necessity for the current research). The literature review section will normally appear after the paragraphs that outline the study’s research question, main findings and theoretical framework. Other science-based degrees may follow the standalone literature review chapter more common in the social sciences.

Strategies for Writing an Effective Literature Review

A research thesis—whether for a Master’s degree or Doctor of Philosophy—is a long project, and the literature review, usually written early on, will most likely be reviewed and refined over the life of the thesis. This section will detail some useful strategies to ensure you write a successful literature review that meets the expectations of your supervisor and examiners.

Using a Mind Map

Before planning or writing, it can be beneficial to undertake a brainstorm exercise to initiate ideas, especially in relation to the organisation of your literature review. A mind map is a very effective technique that can get your ideas flowing prior to a more formal planning process.

A mind map is best created in landscape orientation. Begin by writing a very brief version of your research topic in the middle of the page and then expanding this with themes and sub-themes, identified by keywords or phrases and linked by associations or oppositions. The University of Adelaide provides an excellent introduction to mind mapping.

Planning is as essential at the chapter level as it is for your thesis overall. If you have begun work on your literature review with a mind map or similar process, you can use the themes or organisational categories that emerged to begin organising your content. Plan your literature review as if it were a research essay with an introduction, main body and conclusion.

Create a detailed outline for each main paragraph or section and list the works you will discuss and analyse, along with keywords to identify important themes, arguments and relevant data. By creating a ‘planning document’ in this way, you can keep track of your ideas and refine the plan as you go.

Maintaining a Current Reference List or Annotated Bibliography

It is vital that you maintain detailed and up-to-date records of all scholarly works that you read in relation to your thesis. You will need to ensure that you remain aware of current and developing research, theoretical debates and data as your degree progresses; and review and update the literature review as you work through your own research and writing.

To do this most effectively and efficiently, you will need to record precisely the bibliographic details of each source you use. Decide on the referencing style you will be using at an early stage (this is often dictated by your department or discipline, or suggested by your supervisor). If you begin to construct your reference list as you write your thesis, ensure that you follow any formatting and stylistic requirements for your chosen referencing style from the start (nothing is more onerous than undertaking this task as you are finishing your research degree).

Insert references (also known as ‘citations’) into the text or footnote section as you write your literature review, and be aware of all instances where you need to use a reference . The literature review chapter or section may appear to be overwhelmed with references, but this is just a reflection of the source-based content and purpose.

The Drawbacks of Referencing Software

We don’t recommend the use of referencing software to help you with your references because using this software almost always leads to errors and inconsistencies. They simply can’t be trusted to produce references that will be complete and accurate, properly following your particular referencing style to the letter.

Further, relying on software to create your references for you usually means that you won’t learn how to reference correctly yourself, which is an absolutely vital skill, especially if you are hoping to continue in academia.

Writing Style

Similar to structural matters, your writing style will depend to some extent on your discipline and the expectations and advice of your supervisors. Humanities- and creative arts–based disciplines may be more open to a wider variety of authorial voices. Even if this is so, it remains preferable to establish an academic voice that is credible, engaging and clear.

Simple stylistic strategies such as using the active—instead of the passive—voice, providing variety in sentence structure and length and preferring (where appropriate) simple language over convoluted or overly obscure words can help to ensure your academic writing is both formal and highly readable.

Reviewing, Rewriting and Editing

Although an initial draft is essential (and in some departments it is a formal requirement) to establish the ground for your own research and its place within the wider body of scholarship, the literature review will evolve, develop and be modified as you continue to research, write, review and rewrite your thesis. It is likely that your literature review will not be completed until you have almost finished the thesis itself, and a final assessment and edit of this section is essential to ensure you have included the most important scholarship that is relevant and necessary to your research.

It has happened to many students that a crucial piece of literature is published just as they are about to finalise their thesis, and they must revise their literature review in light of it. Unfortunately, this cannot be avoided, lest your examiners think that you are not aware of this key piece of scholarship. You need to ensure your final literature review reflects how your research now fits into the new landscape in your field after any recent developments.

Mistakes to Avoid

Some common mistakes can result in an ineffective literature review that could then flow on to the rest of your thesis. These mistakes include:

• Trying to read and include everything you find on your topic. The literature review should be selective as well as comprehensive, examining only those sources relevant to your research topic.
• Listing the scholarship as if you are writing an annotated bibliography or a series of summaries. Your discussion of the literature should be synthesised and holistic, and should have a logical progression that is appropriate to the organisation of your content.
• Failing to integrate your examination of the literature with your own thesis topic. You need to develop your discussion of each piece of scholarship in relation to other pieces of research, contextualising your analyses and conclusions in relation to your thesis statement or research topic and focusing on how your own research relates to, complements and extends the existing scholarship.

Writing the literature review is often the first task of your research degree. It is a focused reading and research activity that situates your own research in the wider scholarship, establishing yourself as an active member of the academic community through dialogue and debate. By reading, analysing and synthesising the existing scholarship on your topic, you gain a comprehensive and in-depth understanding, ensuring a solid basis for your own arguments and contributions.

What is a literature review?

Conducting a literature review, organizing a literature review, writing a literature review, helpful book.

• Avoiding Plagiarism
• Google Scholar

A  literature review  is a compilation of the works published in a particular field of study or line of research, usually over a specific period of time, in the form of an in-depth, critical bibliographic essay or annotated list in which attention is drawn to the most significant works.

• Summarizes and analyzes previous research relevant to a topic
• Includes scholarly books and articles published in academic journals
• Can be an specific scholarly paper or a section in a research paper

The objective of a Literature Review is to find previous published scholarly works relevant to an specific topic

• Help gather ideas or information
• Keep up to date in current trends and findings
• Help develop new questions

A literature review is important because it:

• Explains the background of research on a topic
• Demonstrates why a topic is significant to a subject area
• Helps focus your own research questions or problems
• Discovers relationships between research studies/ideas
• Suggests unexplored ideas or populations
• Identifies major themes, concepts, and researchers on a topic
• Tests assumptions; may help counter preconceived ideas and remove unconscious bias
• Identifies critical gaps, points of disagreement, or potentially flawed methodology or theoretical approaches

1. Choose a topic. Define your research question. 

Your literature review should be guided by a central research question. It represents background and research developments related to a specific research question, interpreted, and analyzed by you in a synthesized way. 

• Make sure your research question is not too broad or too narrow.
• Write down terms that are related to your question for they will be useful for searches later. 

2. Decide on the scope of your review. 

How many studies do you need to look at? How comprehensive should it be? How many years should it cover? 

• This may depend on your assignment.
• Consider these things when planning your time for research. 

3. Select the databases you will use to conduct your searches. 

• By Research Guide 

4. Conduct your searches and find the literature. 

• Review the abstracts carefully - this will save you time!
• Many databases will have a search history tab for you to return to for later.
• Use bibliographies and references of research studies to locate others.
• Use citation management software such as Zotero to keep track of your research citations. 

5. Review the literature. 

Some questions to help you analyze the research: 

• What was the research question you are reviewing? What are the authors trying to discover? 
• Was the research funded by a source that could influence the findings? 
• What were the research methodologies? Analyze the literature review, samples and variables used, results, and conclusions. Does the research seem complete? Could it have been conducted more soundly? What further questions does it raise? 
• If there are conflicted studies, why do you think that is? 
• How are the authors viewed in the field? Are they experts or novices? Has the study been cited? 

Source: "Literature Review", University of West Florida,  https://libguides.uwf.edu/c.php?g=215113&p=5139469

A literature review is not a summary of the sources but a synthesis of the sources. It is made up of the topics the sources are discussing. Each section of the review is focused on a topic, and the relevant sources are discussed within the context of that topic. 

1. Select the most relevant material from the sources

• Could be material that answers the question directly
• Extract as a direct quote or paraphrase 

2. Arrange that material so you can focus on it apart from the source text itself

• You are now working with fewer words/passages
• Material is all in one place

3. Group similar points, themes, or topics together and label them 

• The labels describe the points, themes, or topics that are the backbone of your paper’s structure

4. Order those points, themes, or topics as you will discuss them in the paper, and turn the labels into actual assertions

• A sentence that makes a point that is directly related to your research question or thesis 

This is now the outline for your literature review.

• the methodology 
• the quality of the findings or conclusions
• major strengths and weaknesses
• any other important information

Writing Tips: 

• Be selective - Select only the most important points in each source to highlight in the review. It should directly relate to the review's focus.
• Use quotes sparingly.
• Keep your own voice - Your voice (the writer's) should remain front and center. .   
• Aim for one key figure/table per section to illustrate complex content, summarize a large body of relevant data, or describe the order of a process
• Legend below image/figure and above table and always refer to them in text

How to write a PhD literature review WITHOUT using AI (Part 1: Understanding the literature)

• by James Hayton, PhD
• August 26th, 2024

Stay up to date

Should you do a phd, the risks of using ai to write your literature review.

There are countless videos online showing you how to use AI to write your literature review. All of them make it look easy, but all of the ones I’ve seen get fundamental things wrong. And the problem, as with a lot of bad advice, is that it will seem to work at first, but cause major, or even irreparable damage later.

The danger is that AI can help you produce something that looks like a literature review, on a topic you don’t understand. To the uninformed reader it might look impressive, but there won’t be any real insight into the topic. It will probably also contain serious mistakes that you might not notice if you don’t have the expertise.

As I’ve said before, anything you submit as your own work, you have to be able to defend . If you have a lazy examiner who doesn’t read your thesis you might be OK, but a good examiner will quite quickly figure out that you’ve used AI. They will find the parts where you don’t understand what you’ve submitted as your work, and they will, quite rightly, give you a very hard time. And if they discover that you didn’t write major sections of your own thesis, you will fail.

Can AI be used to help you write a literature review?

Can AI be used ethically and effectively? Yes, probably, but if you use it, don’t be dependent on it. You should treat it like an enthusiastic but slightly incompetent intern 1 , in that you can get it to do some work, but you need to check everything it’s done. And while it might make suggestions, never let it make decisions for you.

And if you don’t know enough about a topic to judge what AI is doing, you’ve got to fix that.

You don’t HAVE to use AI for your literature review

I started my PhD in 2003, which means I’m closer to the generation that searched the literature by going to the library 2 and reading physical, printed copies of journals than I am to the current generation with all the AI tools. But despite the advances in technology over the last 21 years, the fundamentals have not changed; you still need a good knowledge and understanding of the literature to be able to write about it.

And isn’t that the point? Surely you want to develop your expertise. You want to know the literature and have some insight of your own, rather than following a chatGPT-generated template. And surely you want to develop your own skills, so you can write with confidence without being dependent on an AI platform.

So here’s how to write a literature review without using AI. It might be slower, especially in the beginning, but you’ll be much stronger for having done the heavy lifting yourself. For now, I’m going to assume that you have some idea what you want to study, but if you want to know how to find, or rather develop, a research topic then leave a comment below and I’ll cover it in a separate video.

Never write about literature you don’t understand

So I’m going to start with a fundamental rule, and that is to never write anything that you don’t understand yourself.

Some people will tell you to take each paper you read and write a summary paragraph, then edit all those paragraphs together, but this is a terrible idea. It’s a terrible idea because when you first start reading, you don’t know how an individual paper fits into the broader context and there might be concepts that you don’t yet understand. You also might not be able to tell if the paper is any good, because not all published papers are.

This is one of the many basic, basic things that the AI advocates fail to acknowledge: a lot of published papers are just bad. So even if you trust the AI platform, which you shouldn’t, you can’t always trust the literature that it’s summarizing.

And if you follow the standard advice of writing these summary paragraphs, or taking key points and then paraphrasing them, without understanding them, you’ll fill pages with content that looks like a literature review, but you will know that you don’t understand what you’re writing about. iAnd if you have any kind of impostor syndrome, this approach is just going to make it worse.

So we have to build some knowledge and understanding of the literature before we can write about it with any confidence. This means forgetting about writing, at least initially, and taking some time to just read.

How to build your knowledge of the academic literature

I can’t give you an exact, step by step process here., because it will vary depending on your situation, your current level of knowledge, the state of your field and what you need to find out. If you want a process that you can just follow from start to finish without thinking or using your own judgement, it doesn’t exist (whether you use AI or not).

But there are general principles you can follow and adapt as your needs change over time. Generally speaking, there are different levels of knowledge you need to develop.

Start with the general trends

Let’s start with the broad picture: This is an understanding of the trends and debates and the kinds of problems people are working on. So we’re not too worried about the details of individual papers here, because initially we’re just getting a low-resolution picture of the field.

And you can usually do this fairly quickly. If you take a handful of recent papers on a specific topic and just read the introductions, you’ll probably notice that they all say similar things about the current state of the field. They will mention the same problems or ongoing debates, they’ll mention many of the same concepts, and they’ll refer to the same key papers.

For example, one of my projects involved looking at silicon nanoparticle luminescence. Basically getting silicon to give off light. Every single paper said the same thing in the introduction; that there had been a surprise result, others had reproduced it but nobody knew the underlying mechanism, and if we could figure it out then there was huge technological potential. There was a lot of heavy technical detail behind it and there were many different experiments and proposed theoretical explanations, but the basic story is easy to understand.

The key paper that everybody referenced was by Canham 3 , a name I still remember two decades later, even though I haven’t looked at the topic since. I don’t remember all the others, but I remember that one. This brings us to the next key point.

Identify the key, influential papers

Not all the literature is of equal value . Most papers have very little impact on the field, but there will be a few that have a disproportionate impact, perhaps because they made some major discovery or invented a new technique or developed a new theory. These get cited far more than anything else.

If everybody else is referring to these people, you need to know who they are and what they did that was so important. And this brings us to the next rule.

Always go back to the original source

Always go back to the original source and check what they actually did and said , because when somebody else summarizes a paper, unless they quote directly, there’s always a subtle change. In some cases, the secondary source explains the concept better, but I’ve seen so many instances where they get it wrong and then other people have cited the secondary source.

So it’s always a good idea to go back to those key original sources and try to understand;

• What problem they addressed
• What they did that was new
• What influence this had on the field

Although it’s important to take some time to try to understand these sources, you maybe don’t need to get too lost in the detail, because you can always come back to these sources multiple times throughout your PhD. And if you come back to a paper a few months or years later, after reading a lot more, after conducting some of your own research, you might have a very different understanding of it.

You should read sources multiple times

A quick side-note here: Years ago, I saw a professor on twitter saying that they “only ever read anything once”. I wish I had saved it because it was such a perfect example of the kind of misleading bullshit you see online, from people who really should know better. Any professor who says they only ever read anything once is either a genius, is lying, or is really bad at their job. Y ou can and should come back to the most important sources and read them multiple times , because your perspective on them will change as your expertise grows.

Learning the basics

As you build this initial picture of the field, the general trends and debates and the key influential figures, you will, inevitably, come across concepts, theories and techniques that you don’t understand. It’s worth taking some time to try to understand some of these.

You need to be selective and prioritize here to avoid getting overwhelmed. Part of this is accepting that you can’t know everything and there will always be gaps in your knowledge. This can be a little scary as you’ve probably come through an education system where you’re graded based on how much of the syllabus you know, but at PhD level we have to let go of that way of thinking because the amount of literature and knowledge is endless.

You’ll never know everything, but you can identify some key concepts that you need to understand for your project.

Know the most common research and analytical techniques

One of the most important aspects here, that’s often overlooked, is developing an understanding of common research and analytical techniques . This is crucial, not only for your own research, but to understand and assess the literature you read.

So many videos I’ve seen about literature reviews just take what the paper says without any critical thought. But you need be able to look at how they conducted their research and reached their conclusions…

It takes time to build this knowledge, so again it’s important to be selective, either based on the kind of research you want to do, or the most common techniques used in the field.

Find good, authoritative sources you can refer back to

It might be worth finding good, authoritative sources on specific techniques. So if you’re doing IPA, for example, get a copy of the book by Smith, Flowers and Larkin . Again, you don’t need get lost in all the detail, but you can get an initial understanding of the basic principles, and then keep going back to that source whenever you need to.

Investing time in that kind of basic understanding will then make it possible to understand the papers that use them.

Highly relevant papers for your specific project

And then, finally, we have specific papers that are highly relevant to your own study. These might be papers that look at the same problem, but from a different perspective, or perhaps serve as a foundation for part of your research. There will probably be a relatively small number of these, but you’ll need to know them really well.

Quick summary of the different levels of knowledge of the literature

To recap, as a foundation, you need

• A basic knowledge of the general trends, problems and debates in your field. You can get this from the introductions of a few papers, or from a good published literature review.
• To know the big, influential papers and what they did that was so important
• To understand the most important concepts and the most commonly used techniques
• To know the most relevant literature for your specific project

And for all of these, you should build up a collection of key, high quality sources that you can go back to whenever you need .

The key word here is quality, because it’s not about the number of papers in your bibliography, but the standard of the sources you rely upon. If you understand even a handful of important papers, it’s far better than having extensive notes or summaries of hundreds of papers that you don’t understand.

Getting into the details

With that strong foundation, you can start to look in more detail at the literature around specific issues of interest, depending on what you need at any given time.

The way you should approach this depends on what you’re trying to do. If need to do a systematic review, then maybe you need to follow PRISMA guidelines . But maybe you’re looking for a solution to a specific problem, or different methods that have been used to measure something, or for the latest, cutting edge results.

To find these, you might need to follow a more organic process, trying out different keyword searches or chasing up references in the bibliographies of papers, or just talking to people , because universities are full of people with useful expertise.

The hard work of searching the literature

However you approach it, there will be dead ends and you will have to sort through a lot of papers that aren’t useful to you (or maybe aren’t useful to you right now), but that’s the nature of academic research.

You might be able to supplement this process using AI, but you cannot delegate the process to AI. You need the ability and the patience to search and filter the literature yourself. It is a fundamental skill that you must have. It’s slow and sometimes frustrating, especially at the start, but you’ll get better and better at filtering through the literature to find the best and most relevant sources as your knowledge grows.

• Literature Review Guidelines

Making sense of what has been written on your topic.

Goals of a literature review:.

Before doing work in primary sources, historians must know what has been written on their topic.  They must be familiar with theories and arguments–as well as facts–that appear in secondary sources.

Before you proceed with your research project, you too must be familiar with the literature: you do not want to waste time on theories that others have disproved and you want to take full advantage of what others have argued.  You want to be able to discuss and analyze your topic.

Your literature review will demonstrate your familiarity with your topic’s secondary literature.

GUIDELINES FOR A LITERATURE REVIEW:

1) LENGTH:  8-10 pages of text for Senior Theses (485) (consult with your professor for other classes), with either footnotes or endnotes and with a works-consulted bibliography. [See also the  citation guide  on this site.]

2) NUMBER OF WORKS REVIEWED: Depends on the assignment, but for Senior Theses (485), at least ten is typical.

3) CHOOSING WORKS:

Your literature review must include enough works to provide evidence of both the breadth and the depth of the research on your topic or, at least, one important angle of it.  The number of works necessary to do this will depend on your topic. For most topics, AT LEAST TEN works (mostly books but also significant scholarly articles) are necessary, although you will not necessarily give all of them equal treatment in your paper (e.g., some might appear in notes rather than the essay). 4) ORGANIZING/ARRANGING THE LITERATURE:

As you uncover the literature (i.e., secondary writing) on your topic, you should determine how the various pieces relate to each other.  Your ability to do so will demonstrate your understanding of the evolution of literature.

You might determine that the literature makes sense when divided by time period, by methodology, by sources, by discipline, by thematic focus, by race, ethnicity, and/or gender of author, or by political ideology.  This list is not exhaustive.  You might also decide to subdivide categories based on other criteria.  There is no “rule” on divisions—historians wrote the literature without consulting each other and without regard to the goal of fitting into a neat, obvious organization useful to students.

The key step is to FIGURE OUT the most logical, clarifying angle.  Do not arbitrarily choose a categorization; use the one that the literature seems to fall into.  How do you do that?  For every source, you should note its thesis, date, author background, methodology, and sources.  Does a pattern appear when you consider such information from each of your sources?  If so, you have a possible thesis about the literature.  If not, you might still have a thesis.

Consider: Are there missing elements in the literature?  For example, no works published during a particular (usually fairly lengthy) time period?  Or do studies appear after long neglect of a topic?  Do interpretations change at some point?  Does the major methodology being used change?  Do interpretations vary based on sources used?

Follow these links for more help on analyzing  historiography  and  historical perspective .

5) CONTENTS OF LITERATURE REVIEW:

The literature review is a research paper with three ingredients:

a) A brief discussion of the issue (the person, event, idea). [While this section should be brief, it needs to set up the thesis and literature that follow.] b) Your thesis about the literature c) A clear argument, using the works on topic as evidence, i.e., you discuss the sources in relation to your thesis, not as a separate topic.

These ingredients must be presented in an essay with an introduction, body, and conclusion.

6) ARGUING YOUR THESIS:

The thesis of a literature review should not only describe how the literature has evolved, but also provide a clear evaluation of that literature.  You should assess the literature in terms of the quality of either individual works or categories of works.  For instance, you might argue that a certain approach (e.g. social history, cultural history, or another) is better because it deals with a more complex view of the issue or because they use a wider array of source materials more effectively. You should also ensure that you integrate that evaluation throughout your argument.  Doing so might include negative assessments of some works in order to reinforce your argument regarding the positive qualities of other works and approaches to the topic.

Within each group, you should provide essential information about each work: the author’s thesis, the work’s title and date, the author’s supporting arguments and major evidence.

In most cases, arranging the sources chronologically by publication date within each section makes the most sense because earlier works influenced later ones in one way or another.  Reference to publication date also indicates that you are aware of this significant historiographical element.

As you discuss each work, DO NOT FORGET WHY YOU ARE DISCUSSING IT.  YOU ARE PRESENTING AND SUPPORTING A THESIS ABOUT THE LITERATURE.

When discussing a particular work for the first time, you should refer to it by the author’s full name, the work’s title, and year of publication (either in parentheses after the title or worked into the sentence).

For example, “The field of slavery studies has recently been transformed by Ben Johnson’s The New Slave (2001)” and “Joe Doe argues in his 1997 study, Slavery in America, that . . . .”

Your paper should always note secondary sources’ relationship to each other, particularly in terms of your thesis about the literature (e.g., “Unlike Smith’s work, Mary Brown’s analysis reaches the conclusion that . . . .” and “Because of Anderson’s reliance on the president’s personal papers, his interpretation differs from Barry’s”). The various pieces of the literature are “related” to each other, so you need to indicate to the reader some of that relationship.  (It helps the reader follow your thesis, and it convinces the reader that you know what you are talking about.)

7) DOCUMENTATION:

Each source you discuss in your paper must be documented using footnotes/endnotes and a bibliography.  Providing author and title and date in the paper is not sufficient.  Use correct Turabian/Chicago Manual of Style form.  [See  Bibliography  and  Footnotes/Endnotes  pages.]

In addition, further supporting, but less significant, sources should be included in  content foot or endnotes .  (e.g., “For a similar argument to Ben Johnson’s, see John Terry, The Slave Who Was New (New York: W. W. Norton, 1985), 3-45.”)

8 ) CONCLUSION OF LITERATURE REVIEW:

Your conclusion should not only reiterate your argument (thesis), but also discuss questions that remain unanswered by the literature.  What has the literature accomplished?  What has not been studied?  What debates need to be settled?

PhD Thesis: Topics, Example, Process, Tips, How to Write?

Muhammad Hasim Sheikh Aug 28, 2024 1K Reads

PhD Thesis or PhD Dissertation is an important component in the process of getting a doctorate. If you are pursuing PhD or deciding to pursue it, it will be mandatory for you to prepare and submit your PhD Thesis.

All the details and information collected during the PhD research are presented in the form of a PhD Thesis. It is a detailed description of the research process of research outcomes that can contribute to the original field of knowledge in the particular field.

The PhD candidates prepare the PhD Thesis to showcase their research findings. A PhD Thesis is the backbone of the doctoral degree and plays an important role in showcasing the research ability and competency in conducting independent and original research.

A PhD Thesis not only demonstrates the research competency of the candidates but also exhibits their expertise, critical thinking, and research skills. The preparation of a PhD Thesis is a very difficult and challenging task and you need to take the utmost precautions while preparing it.

Here in this blog, we will discuss all the procedures adopted while preparing a detailed PhD and high-quality PhD Thesis:

What is the need for PhD Thesis Preparation?

The preparation of a PhD Thesis is crucial as it represents the cumulative research work and outcomes. The PhD Thesis provides a detailed description of the comprehensive research in the particular field. If you are a PhD Scholar, it will be mandatory for you to prepare a PhD Thesis to complete your degree.

It acts as proof of document of your research and findings while pursuing the PhD program. A PhD Thesis also guides the new PhD scholars for reference. Newly enrolled PhD scholars who have just begun their research work can refer to the previous research works conducted by a different researcher in the field to begin his journey.

PhD Thesis is a document that also provides a pathway to new research scholars in the field. The PhD thesis preparation involves organizing and assembling the research findings in a coherent structure. This allows you to refine ideas, identify gaps in the research, and ensure that the arguments are logically presented.

Additionally, you will be able to develop essential skills such as critical thinking, problem-solving, and effective communication that are highly valuable in both academic and professional settings. 

Beginning of the PhD Thesis Writing

PhD Thesis writing begins after completion of the PhD coursework. Every PhD Scholar has to go through a PhD coursework. PhD coursework is offered in the initial years to provide a strong foundation in the research aptitude in the given field.

Once the coursework is completed, a comprehensive exam is conducted to examine and evaluate the ability of the scholars to conduct original research. Generally, the examination is conducted in the 3rd year of the PhD program. Once the examinations are concluded for the coursework, PhD scholars can start working on their PhD Thesis/Dissertation.

Process and Structure of PhD Thesis Writing

Writing a PhD Thesis is a daunting task and one has to go through a prolonged process. It involves several stages and PhD scholars need to through all the stages to prepare a highly inclusive Thesis.

Here is the detailed process and structure of the PhD Thesis:

• Cover Page:  The PhD Thesis writing begins with the preparation of the cover page. The cover page includes the title of the research topic, the name of the university, the name of the scholar, and the supervisor. Generally,  the cover page of the thesis is designed to catch the attention of the viewers.
• Preface: The cover page is followed by the Preface of the PhD Thesis. The Preface is written by the PhD scholars. In the preface of the thesis, they explain the reasons for taking up a particular research topic and their experiences while conducting the research and writing the PhD Thesis. Generally, the preface is written after writing the thesis but arranged after the cover page. 
• Acknowledgment: After writing the Preface of the thesis, PhD scholars begin with the acknowledgment page. Generally, the acknowledgment page of the thesis recognizes all those people who have contributed and given their support in conducting the research. PhD scholars acknowledge the contribution of all the people who have professionally and personally helped in the research. 
• Introduction: In the Introduction, PhD scholars introduce their research topic and explain how this study contributes to the original knowledge of the field. The introduction in the PhD Thesis is a summary of all the key objectives of the research and an explanation of why the particular research is needed. 
• Literature Review: The literature Review in the PhD Thesis is a summary of all the works done by previous researchers and academicians in the same field or field relevant to the topic. In the literature review, all the scholarly works whether books, research journals, research papers, or previous research thesis related to the subject are cited in the PhD Thesis.  A literature review is done to support the current research by analyzing the previous works done on the same subject. 
• Research Chapters: Research Chapters are the crux of the PhD Thesis. In this stage, the PhD Thesis is divided into various chapters. The research conducted by the PhD scholars is recorded in detail in this section. Research Chapters broadly explain the methodology, hypothesis, and original research. The research chapter includes the process of conducting the research on a particular area and the explanation of the research questions. 
• Conclusion: After writing all the research chapters in the PhD Thesis, the conclusion of the research is added. The conclusion is the final chapter of the PhD Thesis Writing that concludes all the research edvideces and findings to reach to a final result. The conclusion also includes the possibilities of further research in the same field and its application to enhance the knowledge of the particular subject. 
• Bibliography and Appendices: The bibliography is written at the end of the PhD Thesis. The Bibliography lists all sources such as books, journals, research papers, thesis, etc used in the PhD Thesis writing. It is written in alphabetical order and includes the author's name, title, publication year, etc. The PhD Scholar may be required to provide supplementary materials that aren't essential to the PhD Thesis in the form of appendices.

What is the Length of the PhDThesis/Dissertation?

The length of the PhD Thesis (or dissertation) greatly depends on the field of the study. Generally, the length of the PhD Thesis ranges between 60,000 to 1,20,000 words which can curated in 150 pages to 300 pages. The average length of the PhD Thesis is around 80,000 words.In general, the length of the PhD Thesis in Engineering and Sciences is shorter than that of Humanities and Social Sciences.

The average length of a PhD Thesis in different disciplines is explained in the table below:

How to Write Up PhD Thesis 

Once all the research related to the relevant topics and subjects has been conducted and all the data and results are collected, you can start with your PhD Thesis Writing.

This period is also known as the Writing Up period. The writing-up stage in a PhD Thesis starts when the original research has already been completed.

In this stage, you only focus on the PhD Thesis Writing and do not conduct any additional research. 

In research related to Humanities and Social sciences, you may already have a large amount of chapter drafts and papers which makes writing up easy. You only need to redraft and assemble these chapter drafts and research papers to formulate a PhD Thesis.

However, writing a PhD Thesis for a Science and Engineering subject may be different. If you are conducting research in these fields, a major part of your research depends on collecting and analyzing data.

Writing Up a PhD Thesis in Science and Engineering fields may require findings and conclusions from the data collected. 

Regardless of the subject and process of PhD Thesis Writing, it should be able to reflect your findings which can be applied in the particular discipline to enhance knowledge. 

Role of PhD Thesis Feedback

Feedback from the supervisor while writing the PhD Thesis plays a crucial role. It helps in formulating a well-organized and highly structured PhD Thesis. You must seek constant feedback from your supervisor on your chapter drafts while writing the PhD Thesis. 

When the thesis writing is in progress, comments and feedback from the supervisor who has significant research experience will ensure that the research is going in the right direction. You must regularly attend the supervisory meeting and present your chapter drafts for review.

Your PhD supervisor will be more than happy to help and guide you through your PhD Thesis Writing. However, PhD supervisor is not responsible for grammatical mistakes. You must ensure that your thesis is free from grammatical errors.

Levels of Plagiarism in PhD Thesis 

While writing the PhD Thesis, you must ensure that your thesis is free from plagiarism. The PhD Thesis must contain your original research and not be copied from anywhere. Plagiarism in a PhD Thesis is considered a serious academic offense and can lead to severe consequences.

If you are giving references to works from other authors, you must give proper citations. Paraphrasing and rephrasing of other’s work must be duly acknowledged. In PhD Thesis Writing, plagiarism is defined on various levels.

Here are the different levels of plagiarism in PhD Thesis Writing:

Penalty for Plagiarism in PhD Thesis/Dissertation 

The University Grants Commission (UGC) takes plagiarism very seriously and sets the penalty standards for different levels of plagiarism.

Here is the punishment for Plagiarism in the PhD Thesis:

Finishing PhD Thesis and Final Submission 

Once you are done with the final draft of the PhD Thesis, you will need to send it to your supervisor. The supervisor will go through the thesis and after reviewing it, approve it for final submission.

Once your supervisor has approved you thesis, submit it for the examination. The Departmental Research Committee (DRC) will examine the PhD Thesis and you will have to appear for the Grand PhD Viva. In this Viva, you will need to defend your research findings and conclusions in the PhD Thesis. 

PhD Thesis submission is done in physical form and you will have to take a printout of the thesis. You should always take multiple printouts of the thesis to avoid any printing mistakes and glitches. At the time of final submission, generally, multiple copies of the thesis are required which makes it more important.

PhD Viva is conducted within 3 months of thesis submission. Once the viva has been completed, the examiners will let you know whether or not you need to make any changes to your PhD Thesis. 

These could be 3 outcomes after thesis submission and viva. All are mentioned below:

If you asked for a correction, you will have to fix the errors and re-submit the PhD thesis again. The re-submission of PhD is usually done digitally.

FAQs (Frequently Asked Questions)

⭐ what is a phd thesis.

A PhD Thesis is a well-structured and well-organized piece of original research that every PhD scholar has to prepare and submit to get their doctorate. 

⭐ Is PhD Viva mandatory after the final submission of the PhD Thesis?

Yes, PhD Viva is mandatory for every PhD Candidate once they have made the final submission of their thesis. In PhD Viva, candidates defend their research and findings before the departmental research committee. 

⭐ What is the ideal length of a PhD Thesis?

There is no ideal length for a PhD Thesis. However, the length of the PhD thesis is greatly influenced by the disciplines of the research. The length of PhD in Engineering and Sciences is comparatively less than that of PhD in Humanities and Social Sciences. The PhD thesis ranges between 60,000 words to 1,20,000 words. 

⭐ What percentage of Plagiarism is allowed for a PhD Thesis?

The University Grants Commission (UGC) allows a maximum of 10 percent plagiarism in the PhD Thesis. The candidates whose thesis plagiarism falls within 10% are not penalized. 

⭐ What is the penalty for Level 2 Plagiarism?

Level 2 plagiarism means that the PhD Thesis has a similarity above 40% to 60%. For this level of plagiarism, the PhD candidate will be asked to withdraw the manuscript and debarred from the annual increment for one year. The supervisor of such PhD scholar will also be penalized with a ban on any PhD supervision for 2 years. 

⭐ What is the Penalty for Level 3 Plagiarism?

Level 3 plagiarism exhibits a similarity above 60% in the PhD Thesis. The PhD Scholars will be asked to withdraw their manuscript and they will be prohibited to annual increments for 2 consecutive years.

Ph.D. in Urban and Regional Planning Degree Information

The doctoral curriculum integrates analytical methods, research design, a rigorous understanding of urbanization dynamics, and an examination of broader social theories, processes and policies.

Students address complex systems that typically encompass an array of spatial, environmental, social, political, technical, and economic factors. The emphasis is on theory, analysis, and action.

Each student is also expected to demonstrate an understanding of the literature, theory, and research in a specialization area within the larger discipline of urban and regional planning.

Required Courses

Four courses are required of all Ph.D. students: two doctoral-level planning theory courses and a two-course research seminar sequence.

• Advanced Urban Theory (URP 700)
• Epistemology and Reasoning for Planning Research (URP 701)
• Research Design (URP 801)
• Ph.D. Research Seminar (URP 802)

Recent students have engaged in subjects as diverse as:

• The political economy of public transit, inner-city revitalization
• Global city urbanization
• Information technology and cyberspace
• The crisis of modernist urbanism
• Suburbanization in developing countries
• Regional planning institutions
• The effects of environmental contamination on patterns of urban and regional development
• The culture of suburban commuting
• The impact of tourism on historical Mediterranean cities
• The application of complex systems analysis to sustainable development

Pre-Candidacy Requirements

Doctoral students specialize in a wide range of possible topics.

• Planning theory
• Analytic methods
• Research design
• Primary area of specialization

Students meet these requirements through coursework and exams over a two-year period. During this time, a student’s cumulative grade point average may not fall below a B without academic discipline or probation.

Analytic Methods Courses

Students are expected to be skilled in statistics, in at least two analytic research techniques, and reasonably knowledgeable about several others. Students qualify in analytic techniques by completing the following:

Satisfactory performance (B or higher) in two cumulative graduate-level statistics courses.

Students entering with previous statistics experience may wish to enter directly into a second semester statistics course. In the past, students have typically selected one of the following sequences:

• Statistics 402 (Introduction to Statistics & Data Analysis), Statistics 403 (Statistics & Data Analysis II)
• Sociology 510 (Statistics); Sociology 610 (Statistical Methods)
• Natural Resources 438 (Natural Resources Biometrics), Natural Resources 538 (Natural Resources Data Analysis)
• Biostatistics 503 (Introductory Biostatistics), Biostatistics 523 (Biostatistical Analysis for Health-Related Fields)
• The sequence in political science

NOTE:  Students wishing to study statistics during the spring or summer terms may want to investigate the Summer Program in Quantitative Methods of Social Research sponsored by the Inter-university Consortium for Political and Social Research (ICPSR) and/or the Summer Institute in Survey Research Techniques conducted by the research staff of the Survey Research Center, Institute for Social Research. Choice of courses to meet requirements should be discussed with your advisor.

Competence in at least two analytic/research methods satisfied through six credit hours of total coursework.

These are methods used in planning research and should prepare the student for their likely area of dissertation work. The requirement is met through completion of nine credits of course work in two analytic/research methods (in addition to statistics), to be defined by the student in conjunction with his or her advisor. (The two methods may be interrelated.) Depending on the research method and the student’s background, more courses may be needed. Courses in these two areas must be completed with a grade of B or higher in order to fulfill this requirement. Graduate level courses that are audited can count for this requirement, as long as the student completes all the work of the course and the instructor provides a letter indicating the grade the student would have received had he or she been enrolled. All plans for satisfying this requirement are the joint responsibility of the student and his or her advisor.

The methods a student selects should relate to their dissertation area. Below are several analytic/research methods in which students have been examined in recent years. Numerous analytic/research methods are appropriate, and students need not be restricted to choices on the list:

• Anthropological methods
• Case study methods
• Complex systems analysis
• Cost benefit & cost effectiveness analysis
• Decision theory & general risk analysis
• Demographic analysis
• Discrete choice analysis
• Differential equations
• Diffusion models
• Economic & other forecasting models
• Evaluation research
• Graph theory
• Historical analysis
• Institutional analysis
• Interview techniques
• Linear programming and general analysis using linear models
• Network & flow methods
• Population growth models
• Probability, both theoretical & heuristic
• Simulation/gaming & game theory
• Spatial analysis
• Survey research
• Time series

Annual Review of Progress

At the end of each year of study, students are required to complete an Annual Review.  The advisor and the Director of Doctoral Studies may make recommendations for any modifications deemed necessary prior to the start of the following academic year. Note: financial support for the subsequent year, if applicable, depends on timely completion of a satisfactory annual review.

Annual Review Steps

By April 15, the student submits:

• A draft annual review form to their advisor, including a concise narrative of and goals for the upcoming summer and academic year.
• An up-to-date CV

The student and advisor meet; the advisor provides comments to the student and, where necessary, recommends changes in the academic plan in the annual review form.

Once the advisor has approved the plan of study for the coming year, they send the Director of Doctoral Studies a short narrative of student progress.

The URP Ph.D. Advisory Committee reviews the materials, and sends a letter to the student, either confirming their good standing in the program or specifying additional requirements to be in good standing.

Comprehensive Exam

The comprehensive exam tests a student’s knowledge of both their primary and secondary areas of specialization. The exam consists of a take-home, written examination followed by an oral exam. The examination normally occurs at the end of the student’s second year, after completion of all relevant coursework.

The Committee

The student convenes an examination committee of three faculty members, choosing faculty who have expertise in the areas of specialization. At least one member of the committee should be a member of the urban and regional planning faculty. The chair or co-chair of the committee must be a regular member of the planning faculty and cannot be an affiliate faculty member. At least one committee member should represent the student’s secondary area of specialization. (If the student has identified a secondary area of specialization that is traditionally housed in another department on campus, then the student is encouraged to select a faculty member from that outside department as their third committee member.) On occasion, examiners from outside the university have served on students’ examining committees. While this practice is generally not encouraged, written requests for an outside examiner by students are treated on an individual basis by the director of doctoral studies.

The Field Statement

The student meets with the committee chair to plan for the exam and agree on expectations prior to the construction of the exam. In consultation with the chair and committee members, the student identifies appropriate readings and prepares a detailed “field statement” that defines the primary and secondary fields, contains a detailed bibliography of readings, organizes the readings into subfields, and outlines a set of major questions for the fields. The field statement is normally designed principally with the chair and is sometimes analogous to a detailed syllabus that one would prepare for a year-long graduate-level course on the selected specializations. The student often writes possible exam questions that he/she feels are appropriate for the area the exam will cover. The questions are not the questions the committee asks the student; their major function is to help the committee and the student to agree on the scope of the exam.

Scheduling the Exam

The exam must be completed by the end of May, at the end of a student’s second year in the program, and is scheduled on the student’s initiative. Prior to the exam, the student should have completed all coursework (including all incompletes). A student may delay the exam for exceptional circumstances with approval of the faculty adviser and the Director of Doctoral Studies. Students must notify the Director of Doctoral Studies of their intent to take the exam, with a date and time, location, and names of committee members at least one month prior to the exam.

The written part of the exam is in the form of a take-home essay. The committee chair typically solicits exam questions from the committee, selects questions to be used, and composes the final examination. The allotted time period to write the exam is determined by the chair, and typically is over three days. The student must submit the exam in the form as directed by the chair (usually as a Word document submitted by email), plus one copy to the program administrator to be placed in the student’s records. The written exam is followed by a two-hour oral exam, generally scheduled to take place within about one week after the written exam. The exam is evaluated on a “Pass/Fail” or “Conditional Pass” basis. If the student does not achieve a passing evaluation, he/she may take the exam one additional time to achieve a “Pass” or “Conditional Pass” status. A “Conditional Pass” indicates that additional requirements must be met, but the exam need not be retaken. Upon completion of the oral portion of the exam, please refer to the Applying for Candidacy section for next steps.

Applying for Candidacy

A student advances to candidacy when all program requirements except the dissertation proposal and dissertation have been satisfied. The normal and expected time to achieve candidacy is two years from the date of first enrollment in the doctoral program. In addition to urban and regional planning program requirements, a student must also meet  Rackham Candidacy Requirements . Any incomplete courses that are critical to satisfying requirements must be completed before applying for candidacy.

Once all required coursework and the comprehensive exam are successfully completed, a student applies for Candidacy by sending a request by email to the URP Director of Doctoral Studies, along with a signed Comprehensive Exam Certification Form.

The Director of Doctoral Studies will recommend a doctoral student for candidacy by submitting a recommendation to the Rackham Graduate School. When candidacy is approved, a student is ready to begin work on the dissertation and is eligible for URP 995 candidacy registration.

Sample Second Year

Spring – Summer
(scheduled by student; typically taken by the end of May)
(by the start of the third year of study) Sample Years Three – Four Dissertation Proposal Presentation (reviewed and approved by the student’s dissertation committee and the URP Doctoral Committee) Dissertation research and writing Informal “Full Draft Review” (at least 6-8 weeks before the formal defense) Dissertation Defense Submittal of the final version of the dissertation Dissertation Forming dissertation committee. After completing the comprehensive exam and advancing to candidacy, the student must form a dissertation committee, in accordance with the Rackham Graduate School’s  “Guidelines for Dissertation Committee Service.” The Dissertation Committee should be formed prior to defending the dissertation proposal, which should be formed several months before the student expects to defend their proposal URP. When prepared to do so, the student should send the Director of Doctoral Studies and Lisa Hauser the completed “Dissertation Committee Worksheet for Students to submit to Program”, which can be obtained from the link above. The Director of Doctoral Studies and Lisa Hauser will then submit the formal request to the Rackham Graduate School. Dissertation Proposal Dissertation proposals can be defended anytime after taking the Comprehensive Exam, but no later than the end of the fifth semester (i.e. December). It is the student’s responsibility to schedule the proposal defense attended by the dissertation committee. The student must notify Lisa Hauser by email of the proposal defense date at least three weeks prior to the meeting, including the location of the defense meeting, a title, and an abstract. After gaining approval from the dissertation committee, the dissertation chair must send an email to the Director of Doctoral Studies that includes (a) the date of the proposal defense, (b) a list of all committee members present at the defense, (c) a title of the proposal, (d) an abstract of the proposal (250 – 350 words), and (e) a copy of the final dissertation proposal to be filed with URP records. Receipt of the email from the dissertation chair will constitute formal approval of the proposal by the committee and readiness to proceed with dissertation work. Dissertation Process The dissertation is prepared in accordance with the  Rackham Graduate School’s Doctoral Dissertation Requirements , and as outlined in the URP Ph.D. Program Overview Schedule and Policies document. The student is responsible for several steps: (a) scheduling and reserving rooms (and/or a Zoom link if virtual or hybrid) for the URP pre-defense hearing (which ordinarily should occur at least six weeks and no less than three weeks prior to the dissertation defense) and the defense meeting, both in a timely manner; (b) notifying Lisa Hauser by email of the defense date at least three weeks prior to the meeting, including the location of the defense meeting, (and Zoom link, if relevant), a title, and an abstract; (c) providing a complete dissertation draft, including an abstract and bibliography, to committee members at least two weeks (longer is advised) before the defense date; and (d) registering for an eight-hour candidacy enrollment (995 Dissertation Research) for the term in which the defense is held. A dissertation defense typically consists of two parts: the first is a formal, public presentation of the dissertation research, followed by questions and answers from both the dissertation committee and the audience. Defenses are advertised and open to the public, and other students and faculty are frequently in attendance. The second part is a closed session for the candidate and the dissertation committee. During the defense, the student may be asked to reconsider certain aspects of the work and to make changes or corrections in the dissertation. At the end of the session, the chair will discuss the oral defense with other members of the committee and inform the student of the outcome. The duration of a defense can vary, but the candidate should reserve the room for a three-hour period. Formal approval of the dissertation (e.g., formatting of the final document) and applying for graduation are governed by the Rackham Graduate School.

This means anyone with GCSE results from 2017-2020 will have a combination of both letters and numbers.   The numerical grading system was to signal more challenging GCSEs and to better differentiate between students’ abilities - particularly at higher grades between the A *-C grades. There only used to be 4 grades between A* and C, now with the numerical grading scale there are 6.   What do the number grades mean?   The grades are ranked from 1, the lowest, to 9, the highest.   The grades don’t exactly translate, but the two grading scales meet at three points as illustrated below.   The bottom of grade 7 is aligned with the bottom of grade A, while the bottom of grade 4 is aligned to the bottom of grade C.     Meanwhile, the bottom of grade 1 is aligned to the bottom of grade G.   What to do if your results weren’t what you were expecting?   If your results weren’t what you were expecting, firstly don’t panic. You have options.   First things first, speak to your school or college – they could be flexible on entry requirements if you’ve just missed your grades.    They’ll also be able to give you the best tailored advice on whether re-sitting while studying for your next qualifications is a possibility.    If you’re really unhappy with your results you can enter to resit all GCSE subjects in summer 2025. You can also take autumn exams in GCSE English language and maths.   Speak to your sixth form or college to decide when it’s the best time for you to resit a GCSE exam.   Look for other courses with different grade requirements      Entry requirements vary depending on the college and course. Ask your school for advice, and call your college or another one in your area to see if there’s a space on a course you’re interested in.     Consider an apprenticeship     Apprenticeships combine a practical training job with study too. They’re open to you if you’re 16 or over, living in England, and not in full time education.   As an apprentice you’ll be a paid employee, have the opportunity to work alongside experienced staff, gain job-specific skills, and get time set aside for training and study related to your role.    You can find out more about how to apply here .   Talk to a National Careers Service (NCS) adviser     The National Career Service is a free resource that can help you with your career planning. Give them a call to discuss potential routes into higher education, further education, or the workplace.    Whatever your results, if you want to find out more about all your education and training options, as well as get practical advice about your exam results, visit the  National Careers Service page  and Skills for Careers to explore your study and work choices.    You may also be interested in: Results day 2024: What's next after picking up your A level, T level and VTQ results?
