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.

  • To convey to your reader what knowledge and ideas have been established on a topic
  • To explain what the strengths and weaknesses of that knowledge and those ideas might be
  • To learn how others have defined and measured key concepts    
  • To keep the writer/reader up to date with current developments and historical trends in a particular field or discipline
  • To establish context for the argument explored in the rest of a paper
  • To provide evidence that may be used to support your own findings
  • To demonstrate your understanding and your ability to critically evaluate research in the field
  • To suggest previously unused or underused methodologies, designs, and quantitative and qualitative strategies
  • To identify gaps in previous studies and flawed methodologies and/or theoretical approaches in order to avoid replication of mistakes
  • To help the researcher avoid repetition of earlier research
  • To suggest unexplored populations
  • To determine whether past studies agree or disagree and identify strengths and weaknesses on both sides of a controversy in the literature

Cat

  • Choose a topic that is interesting to you; this makes the research and writing process more enjoyable and rewarding.
  • For a literature review, you'll also want to make sure that the topic you choose is one that other researchers have explored before so that you'll be able to find plenty of relevant sources to review.

  • Your research doesn't need to be exhaustive. Pay careful attention to bibliographies. Focus on the most frequently cited literature about your topic and literature from the best known scholars in your field. Ask yourself: "Does this source make a significant contribution to the understanding of my topic?"
  • Reading other literature reviews from your field may help you get ideas for themes to look for in your research. You can usually find some of these through the library databases by adding literature review as a keyword in your search.
  • Start with the most recent publications and work backwards. This way, you ensure you have the most current information, and it becomes easier to identify the most seminal earlier sources by reviewing the material that current researchers are citing.

The organization of your lit review should be determined based on what you'd like to highlight from your research. Here are a few suggestions:

  • Chronology : Discuss literature in chronological order of its writing/publication to demonstrate a change in trends over time or to detail a history of controversy in the field or of developments in the understanding of your topic.  
  • Theme: Group your sources by subject or theme to show the variety of angles from which your topic has been studied. This works well if, for example, your goal is to identify an angle or subtopic that has so far been overlooked by researchers.  
  • Methodology: Grouping your sources by methodology (for example, dividing the literature into qualitative vs. quantitative studies or grouping sources according to the populations studied) is useful for illustrating an overlooked population, an unused or underused methodology, or a flawed experimental technique.

  • Be selective. Highlight only the most important and relevant points from a source in your review.
  • Use quotes sparingly. Short quotes can help to emphasize a point, but thorough analysis of language from each source is generally unnecessary in a literature review.
  • Synthesize your sources. Your goal is not to make a list of summaries of each source but to show how the sources relate to one another and to your own work.
  • Make sure that your own voice and perspective remains front and center. Don't rely too heavily on summary or paraphrasing. For each source, draw a conclusion about how it relates to your own work or to the other literature on your topic.
  • Be objective. When you identify a disagreement in the literature, be sure to represent both sides. Don't exclude a source simply on the basis that it does not support your own research hypothesis.
  • At the end of your lit review, make suggestions for future research. What subjects, populations, methodologies, or theoretical lenses warrant further exploration? What common flaws or biases did you identify that could be corrected in future studies?

  • Double check that you've correctly cited each of the sources you've used in the citation style requested by your professor (APA, MLA, etc.) and that your lit review is formatted according to the guidelines for that style.

Your literature review should:

  • Be focused on and organized around your topic.
  • Synthesize your research into a summary of what is and is not known about your topic.
  • Identify any gaps or areas of controversy in the literature related to your topic.
  • Suggest questions that require further research.
  • Have your voice and perspective at the forefront rather than merely summarizing others' work.

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.

Prevent plagiarism. Run a free check.

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 .

Basic Principles of Citation

APA Style uses the author–date citation system , in which a brief in-text citation directs readers to a full reference list entry. The in-text citation appears within the body of the paper (or in a table, figure, footnote, or appendix) and briefly identifies the cited work by its author and date of publication. This enables readers to locate the corresponding entry in the alphabetical reference list at the end of the paper.

Each work cited must appear in the reference list, and each work in the reference list must be cited in the text (or in a table, figure, footnote, or appendix).

Both paraphrases and quotations require citations.

The following are guidelines to follow when writing in-text citations:

  • Ensure that the spelling of author names and the publication dates in reference list entries match those in the corresponding in-text citations.
  • Cite only works that you have read and ideas that you have incorporated into your writing. The works you cite may provide key background information, support or dispute your thesis, or offer critical definitions and data.
  • Readers may find a long string of citations difficult to understand, especially if they are using assistive technology such as a screen reader; therefore, include only those citations needed to support your immediate point.
  • Cite primary sources when possible, and cite secondary sources sparingly.
  • Cite sources to document all facts and figures that you mention that are not common knowledge.
  • To cite a specific part of a source , provide an author–date citation for the work plus information about the specific part.
  • Even when sources cannot be retrieved (e.g., because they are personal communications ), still credit them in the text (however, avoid using online sources that are no longer recoverable).

Basic principles of citation are covered in the seventh edition APA Style manuals in the Publication Manual Sections 8.1 to 8.36 and the Concise Guide Sections 8.1 to 8.34

What is a Literature Review?

The literature review is a written explanation by you, the author, of the research already done on the topic, question or issue at hand. What do we know (or not know) about this issue/topic/question?

  • A literature review provides a thorough background of the topic by giving your reader a guided overview of major findings and current gaps in what is known so far about the topic. 
  • The literature review is not a list (like an annotated bibliography) -- it is a narrative helping your reader understand the topic and where you will "stand" in the debate between scholars regarding the interpretation of meaning and understanding why things happen. Your literature review  helps your reader start to see the "camps" or "sides" within a debate, plus who studies the topic and their arguments. 
  • A good literature review should help the reader sense how you will answer your research question and should highlight the preceding arguments and evidence you think are most helpful in moving the topic forward.
  • The purpose of the literature review is to dive into the existing debates on the topic to learn about the various schools of thought and arguments, using your research question as an anchor. If you find something that doesn't help answer your question, you don't have to read (or include) it. That's the power of the question format: it helps you filter what to read and include in your literature review, and what to ignore.

How Do I Start?

Essentially you will need to:

  • Identify and evaluate relevant literature (books, journal articles, etc.) on your topic/question.

Conduct a literature review

What is a literature review.

A literature review is a summary of the published work in a field of study. This can be a section of a larger paper or article, or can be the focus of an entire paper. Literature reviews show that you have examined the breadth of knowledge and can justify your thesis or research questions. They are also valuable tools for other researchers who need to find a summary of that field of knowledge.

Unlike an annotated bibliography, which is a list of sources with short descriptions, a literature review synthesizes sources into a summary that has a thesis or statement of purpose—stated or implied—at its core.

How do I write a literature review?

Step 1: define your research scope.

  • What is the specific research question that your literature review helps to define?
  • Are there a maximum or minimum number of sources that your review should include?

Ask us if you have questions about refining your topic, search methods, writing tips, or citation management.

Step 2: Identify the literature

Start by searching broadly. Literature for your review will typically be acquired through scholarly books, journal articles, and/or dissertations. Develop an understanding of what is out there, what terms are accurate and helpful, etc., and keep track of all of it with citation management tools . If you need help figuring out key terms and where to search, ask us .

Use citation searching to track how scholars interact with, and build upon, previous research:

  • Mine the references cited section of each relevant source for additional key sources
  • Use Google Scholar or Scopus to find other sources that have cited a particular work

Step 3: Critically analyze the literature

Key to your literature review is a critical analysis of the literature collected around your topic. The analysis will explore relationships, major themes, and any critical gaps in the research expressed in the work. Read and summarize each source with an eye toward analyzing authority, currency, coverage, methodology, and relationship to other works. The University of Toronto's Writing Center provides a comprehensive list of questions you can use to analyze your sources.

Step 4: Categorize your resources

Divide the available resources that pertain to your research into categories reflecting their roles in addressing your research question. Possible ways to categorize resources include organization by:

  • methodology
  • theoretical/philosophical approach

Regardless of the division, each category should be accompanied by thorough discussions and explanations of strengths and weaknesses, value to the overall survey, and comparisons with similar sources. You may have enough resources when:

  • You've used multiple databases and other resources (web portals, repositories, etc.) to get a variety of perspectives on the research topic.
  • The same citations are showing up in a variety of databases.

Writing an effective literature review

Lorelei lingard.

Schulich School of Medicine & Dentistry, Health Sciences Addition, Western University, London, Ontario Canada

In the Writer’s Craft section we offer simple tips to improve your writing in one of three areas: Energy, Clarity and Persuasiveness. Each entry focuses on a key writing feature or strategy, illustrates how it commonly goes wrong, teaches the grammatical underpinnings necessary to understand it and offers suggestions to wield it effectively. We encourage readers to share comments on or suggestions for this section on Twitter, using the hashtag: #how’syourwriting?

This Writer’s Craft instalment is the second in a two-part series that offers strategies for effectively presenting the literature review section of a research manuscript. This piece argues that citation is not just a technical practice but also a rhetorical one, and offers writers an expanded vocabulary for using citation to maximal effect.

Many writers think of citation as the formal system we use to avoid plagiarism and acknowledge others’ work. But citation is a much more nuanced practice than this. Not only does citation allow us to represent the source of knowledge, but it also allows us to position ourselves in relation to that knowledge, and to place that knowledge in relation to other knowledge . In short, citation is how we artfully tell the story of what the field knows, how it came to that knowledge, and where we stand in relation to it as we write the literature review section to frame our own work. Seen this way, citation is a sophisticated task, requiring in-depth knowledge of the literature in a domain.

Citation is more than just referencing; it is how we represent the social construction of knowledge in a field. A citation strategy is any indication in the text about the source and nature of knowledge. Consider the following passage, in which all citation strategies are italicized:

Despite years of effort to teach and enforce positive professional norms and standards, many reports of challenges to medical professionalism continue to appear, both in the medical and education literature and, often in reaction, in the lay press . 1,2,3,4,5 Examples of professional lapses dot the health care landscape: regulations are thwarted, records are falsified, patients are ignored, colleagues are berated. 2,4,6 The medical profession has articulated its sense of what professionalism is in a number of important position statements . 7,8 These statements tend to be built upon abstracted principles and values, such as the taxonomy presented in the American Board of Internal Medicine’s (ABIM’s) Project Professionalism : altruism, accountability, excellence, duty, honour, integrity, and respect for others. 7 (From Ginsburg et al., The anatomy of a professional lapse [ 1 ])

In this passage, citation as referencing (in the form of Vancouver format superscript numbers) is used to acknowledge the source of knowledge. There are more than just references in this passage, however. Citation strategies also include statements that characterize the density of that knowledge (‘many reports’), its temporal patterns (‘continue to appear’), its diverse origins (‘both in the medical and education literature’), its social nature (‘often in reaction’), and its social import (‘important position statements’). Citation does more than just acknowledge the source of something you’ve read. It is how you represent the social nature of knowledge as coming from somewhere, being debated and developed, and having impact on the world [ 2 ]. If we remove all these citation strategies, the passage sounds at best like common sense or, at worst, like unsubstantiated personal opinion:

Despite years of effort to teach and enforce positive professional norms and standards, challenges to medical professionalism continue. Examples of professional lapses dot the health care landscape: regulations are thwarted, records are falsified, patients are ignored, colleagues are berated. Professionalism is a set of principles and values: altruism, accountability, excellence, duty, honour, integrity, and respect for others.

But perhaps you’ve been told that your literature review should be ‘objective’—that you should simply present what is known without taking a stance on it. This is largely untrue, for two reasons. The first involves the distinction between summary and critical summary. A summary is a neutral description of material, but a good literature review contains very little pure summary because, as we review, we must also judge the quality, source and reliability of the knowledge claims we are presenting [ 3 ]. To do this, we engage in critical summary, not only summarizing existing knowledge but offering a stance on it.

The second reason is that, even when we’re aiming for simple summary, a completely neutral presentation of knowledge claims is very difficult to achieve. We take a stance in ways we hardly even notice. Consider how the verb in each of these statements adds a flavour of stance to what is otherwise a summary of a knowledge claim in the field:

Anderson describes how the assessment is overly time-consuming for use in the Emergency Department. Anderson discovered that the assessment was overly time-consuming for use in the Emergency Department. Anderson claims that the assessment is overly time-consuming for use in the Emergency Department.

The first verb, ‘describes’, is neutral: it is not possible to ascertain the writer’s stance on the knowledge Anderson has contributed to the field. The second verb, ‘discovered’, expresses an affiliation or positive stance in the writer, while the third verb, ‘claims’, distances the writer from Anderson’s work. Even these brief summary sentences contain a flavour of critical summary. This is not a flaw; in fact, it is an important method of portraying existing knowledge as a conversation in which the writer is positioning herself and her work. But it should be done consciously and strategically. Tab.  1 offers examples to help writers think about how the verbs in their literature review position them in relation to existing knowledge in the field. Meaning is subject to context and these examples should only be taken as a guide: e. g., ‘suggests’ can be used to signal neutrality or distancing.

Verbs to position the writer in relation to the literature being reviewed

Neutral about the knowledgeAffiliating with the knowledgeDistancing from the knowledge
comments
explains
indicates
notes
describes
observes
remarks
states
finds
discovers
reveals
realizes
understands
addresses
argues
recognizes
identifies
assumes
claims
contends
argues
hopes
believes

Most of us have favourite verbs that we default to almost unconsciously when we are writing—reports, argues, describes, studies, explains, asserts—but these verbs are not interchangeable. They each inscribe a slightly different stance towards the knowledge—not only the writer’s stance, but also the stance of the researcher who created the knowledge. It is critical to get the original stance right in your critical summary. Nothing irritates me more than seeing my stance mispresented in someone else’s literature review. For example, if I wrote a paragraph offering tentative reflections on a new idea, I don’t want to see that summarized in someone’s literature review as ‘Lingard argues’, when more accurate would be ‘Lingard suggests’ or ‘Lingard explored’.

Writers need to extend their library of citation verbs to allow themselves to accurately and persuasively position knowledge claims published by authors in their field. You can find many online resources to help extend your vocabulary: Tab.  2 , adapted from one such online source [ 4 ], provides some suggestions. Tables like these should be thought of as tools, not rules—keep in mind that words have flexible meanings depending on context and purpose. This is why one word, such as suggest or conclude , can appear in more than one list.

Verbs to represent the nature and strength of an author’s contributions to the literature

Verbs to report what an author DIDVerbs to report what an author SAIDVerbs to report an author’s OPINION
analyse, assess, , discover, describe, demonstrate, examine, explore, establish, find, identify, inquire, prove, observe, study, showWeakerStrongerWeakerStronger
comment, describe, note, remark, add, offer, affirm, emphasize, stress, maintain, stipulate, explain, , identify, insistaccept, believe, consider, think, , suspect, speculateargue, assert, claim, contend, deny, recommend, reject, advocate, maintain

Knowledge is a social construction and it accumulates as researchers debate, extend and refine one another’s contributions. To avoid your literature review reading like a laundry list of disconnected ‘facts’, reporting verbs are an important resource. Tab.  3 offers a selection of verbs organized to reflect different relationships among authors in the field of knowledge being reviewed.

Verbs to express relations among authors in the field

Depicting similar positionsDepicting contrasting positionsDepicting relating/responding positions
Taylor Jackson’s claim that …Taylor Jackson’s claim that …Taylor to Jackson’s claim that …
affirms, agrees, confirms, concurs, aligns, shares, echoes, supports, verifies, concedes, acceptsargues, disagrees, questions, dismisses, refuses, rejects, challenges contradicts, criticizes, opposes, counters, disputesextends, elaborates, refines, builds on, reconsiders, draws upon, advances, repositions, addresses

Finally, although we have focused on citation verbs in this article, adverbs (e. g., similarly, consequently) and prepositional phrases (e. g., by contrast, in addition) are also important for expressing similar, contrasting or responding relations among knowledge claims and their authors in the field being reviewed.

In summary, an effective literature review not only summarizes existing knowledge, it also critically presents that knowledge to depict an evolving conversation and understanding in a particular domain of study. As writers we need to know when we are summarizing and when we are critically summarizing—summary alone makes for a literature review that reads like a laundry list of undigested ‘facts-in-the-world’. Finally, writers need to attend to the subtle power of citation verbs to position themselves and the authors they are citing in relation to the knowledge being reviewed. Broadening our catalogue of ‘go-to’ verbs is an important step in enlivening and strengthening our writing.

1. How should a student begin the research process for a paper?

Assignments will vary from teacher to teacher, but it is never a bad idea to start in reference for an overview of the topic.  Then the student should progress to the catalog to search for additional books and the online databases to search for articles.  Librarians are happy to assist with any research needs.

2. What is the difference between searching an online database and searching on the Internet?

When searching online databases, students will find articles that can be considered as respected, verifiable research sources.  Typically students will find articles from magazines, scholarly journals, and reference books in these databases and can be assured that the sources are appropriate for academic writing. 

When searching the Internet, students may find good information, but extra steps are needed in verifying the validity/accuracy of such information.  In addition, most Internet sources are typically not considered academic/scholarly and may be disallowed by many teachers.  The library staff is happy to answer any questions about evaluating Internet sources.

3. What is an annotated bibliography?

An annotated bibliography is just like a standard bibliography with the addition of a summary of each source.  Information on annotated bibliographies can be found by visiting “How to Prepare an Annotated Bibliography” (courtesy of Cornell University Library). 

Information on MLA style can be found by visiting “MLA Style,” (courtesy of Williams College Libraries).

4. How can a student avoid plagiarism?

Plagiarism is a serious offense and cannot be fully addressed in a short answer.  Generally, you always give credit to ideas you are quoting or paraphrasing.  For more specific information, ask your teacher, ask a librarian, or visit the very detailed plagiarism handout created by the Purdue University Online Writing Lab (OWL) .

How to write a literature review in 6 steps

Literature review for thesis

What is a literature review?

How to write a literature review, 1. determine the purpose of your literature review, 2. do an extensive search, 3. evaluate and select literature, 4. analyze the literature, 5. plan the structure of your literature review, 6. write your literature review, other resources to help you write a successful literature review, frequently asked questions about writing a literature review, related articles.

A literature review is an assessment of the sources in a chosen topic of research.

A good literature review does not just summarize sources. It analyzes the state of the field on a given topic and creates a scholarly foundation for you to make your own intervention. It demonstrates to your readers how your research fits within a larger field of study.

In a thesis, a literature review is part of the introduction, but it can also be a separate section. In research papers, a literature review may have its own section or it may be integrated into the introduction, depending on the field.

➡️ Our guide on what is a literature review covers additional basics about literature reviews.

  • Identify the main purpose of the literature review.
  • Do extensive research.
  • Evaluate and select relevant sources.
  • Analyze the sources.
  • Plan a structure.
  • Write the review.

In this section, we review each step of the process of creating a literature review.

In the first step, make sure you know specifically what the assignment is and what form your literature review should take. Read your assignment carefully and seek clarification from your professor or instructor if needed. You should be able to answer the following questions:

  • How many sources do I need to include?
  • What types of sources should I review?
  • Should I evaluate the sources?
  • Should I summarize, synthesize or critique sources?
  • Do I need to provide any definitions or background information?

In addition to that, be aware that the narrower your topic, the easier it will be to limit the number of sources you need to read in order to get a good overview of the topic.

Now you need to find out what has been written on the topic and search for literature related to your research topic. Make sure to select appropriate source material, which means using academic or scholarly sources , including books, reports, journal articles , government documents and web resources.

➡️ If you’re unsure about how to tell if a source is scholarly, take a look at our guide on how to identify a scholarly source .

Come up with a list of relevant keywords and then start your search with your institution's library catalog, and extend it to other useful databases and academic search engines like:

  • Google Scholar
  • Science.gov

➡️ Our guide on how to collect data for your thesis might be helpful at this stage of your research as well as the top list of academic search engines .

Once you find a useful article, check out the reference list. It should provide you with even more relevant sources. Also, keep a note of the:

  • authors' names
  • page numbers

Keeping track of the bibliographic information for each source will save you time when you’re ready to create citations. You could also use a reference manager like Paperpile to automatically save, manage, and cite your references.

Paperpile reference manager

Read the literature. You will most likely not be able to read absolutely everything that is out there on the topic. Therefore, read the abstract first to determine whether the rest of the source is worth your time. If the source is relevant for your topic:

  • Read it critically.
  • Look for the main arguments.
  • Take notes as you read.
  • Organize your notes using a table, mind map, or other technique.

Now you are ready to analyze the literature you have gathered. While your are working on your analysis, you should ask the following questions:

  • What are the key terms, concepts and problems addressed by the author?
  • How is this source relevant for my specific topic?
  • How is the article structured? What are the major trends and findings?
  • What are the conclusions of the study?
  • How are the results presented? Is the source credible?
  • When comparing different sources, how do they relate to each other? What are the similarities, what are the differences?
  • Does the study help me understand the topic better?
  • Are there any gaps in the research that need to be filled? How can I further my research as a result of the review?

Tip: Decide on the structure of your literature review before you start writing.

There are various ways to organize your literature review:

  • Chronological method : Writing in the chronological method means you are presenting the materials according to when they were published. Follow this approach only if a clear path of research can be identified.
  • Thematic review : A thematic review of literature is organized around a topic or issue, rather than the progression of time.
  • Publication-based : You can order your sources by publication, if the way you present the order of your sources demonstrates a more important trend. This is the case when a progression revealed from study to study and the practices of researchers have changed and adapted due to the new revelations.
  • Methodological approach : A methodological approach focuses on the methods used by the researcher. If you have used sources from different disciplines that use a variety of research methods, you might want to compare the results in light of the different methods and discuss how the topic has been approached from different sides.

Regardless of the structure you chose, a review should always include the following three sections:

  • An introduction, which should give the reader an outline of why you are writing the review and explain the relevance of the topic.
  • A body, which divides your literature review into different sections. Write in well-structured paragraphs, use transitions and topic sentences and critically analyze each source for how it contributes to the themes you are researching.
  • A conclusion , which summarizes the key findings, the main agreements and disagreements in the literature, your overall perspective, and any gaps or areas for further research.

➡️ If your literature review is part of a longer paper, visit our guide on what is a research paper for additional tips.

➡️ UNC writing center: Literature reviews

➡️ How to write a literature review in 3 steps

➡️ How to write a literature review in 30 minutes or less

The goal of a literature review is to asses the state of the field on a given topic in preparation for making an intervention.

A literature review should have its own independent section. You should indicate clearly in the table of contents where it can be found, and address this section as “Literature Review.”

There is no set amount of words for a literature review; the length depends on the research. If you are working with a large amount of sources, then it will be long. If your paper does not depend entirely on references, then it will be short.

Most research papers include a literature review. By assessing the available sources in your field of research, you will be able to make a more confident argument about the topic.

Literature reviews are most commonly found in theses and dissertations. However, you find them in research papers as well.

how to write citation in literature review

Researching and writing for Economics students

4 literature review and citations/references.

Literature reviews and references

Figure 4.1: Literature reviews and references

Your may have done a literature survey as part of your proposal. This will be incorporated into your dissertation, not left as separate stand-alone. Most economics papers include a literature review section, which may be a separate section, or incorporated into the paper’s introduction. (See organising for a standard format.)

Some disambiguation:

A ‘Literature survey’ paper: Some academic papers are called ‘literature surveys’. These try to summarise and discuss the existing work that has been done on a particular topic, and can be very useful. See, for example, works in The Journal of Economic Perspectives, the Journal of Economic Literature, the “Handbook of [XXX] Economics”

Many student projects and undergraduate dissertations are mainly literature surveys.

4.1 What is the point of a literature survey?

Your literature review should explain:

what has been done already to address your topic and related questions, putting your work in perspective, and

what techniques others have used, what are their strengths and weaknesses, and how might they be relevant tools for your own analysis.

Take notes on this as you read, and write them up.

Figure 4.2: Take notes on this as you read, and write them up.

4.2 What previous work is relevant?

Focus on literature that is relevant to your topic only.

But do not focus only on articles about your exact topic ! For example, if your paper is about the relative price of cars in the UK, you might cite papers (i) about the global automobile market, (ii) about the theory and evidence on competition in markets with similar features and (iii) using econometric techniques such as “hedonic regression” to estimate “price premia” in other markets and in other countries.

Consider: If you were Colchester a doctor and wanted to know whether a medicine would be effective for your patients, would you only consider medical studies that ran tests on Colchester residents, or would you consider more general national and international investigations?

4.3 What are “good” economics journal articles?

You should aim to read and cite peer-reviewed articles in reputable economics journals. (Journals in other fields such as Finance, Marketing and Political Science may also be useful.) These papers have a certain credibility as they have been checked by several referees and one or more editors before being published. (In fact, the publication process in Economics is extremely lengthy and difficult.)

Which journals are “reputable”? Economists spend a lot of time thinking about how to rank and compare journals (there are so many papers written about this topic that they someone could start a “Journal of Ranking Economics Journals”. For example, “ REPEC ” has one ranking, and SCIMAGO/SCOPUS has another one. You may want to focus on journals ranked in the top 100 or top 200 of these rankings. If you find it very interesting and relevant paper published somewhere that is ranked below this, is okay to cite it, but you may want to be a bit more skeptical of its findings.

Any journal you find on JSTOR is respectable, and if you look in the back of your textbooks, there will be references to articles in journals, most of which are decent.

You may also find unpublished “working papers”; these may also be useful as references. However, it is more difficult to evaluate the credibility of these, as they have not been through a process of peer review. However, if the author has published well and has a good reputation, it might be more likely that these are worth reading and citing.

Unpublished “working papers”

You may also find unpublished “working papers” or ‘mimeos’; these may also be useful as references. In fact, the publication process in Economics is so slow (six years from first working paper to publication is not uncommon) that not consulting working papers often means not being current.

However, it is more difficult to evaluate the credibility of this ‘grey literature’, as they have not been through a process of peer review. However, if the author has published well and has a good reputation, it might be more likely that these are worth reading and citing. Some working paper series are vetted, such as NBER; in terms of credibility, these might be seen as something in between a working paper and a publication.

Which of the following are “peer-reviewed articles in reputable economics journals”? Which of the following may be appropriate to cite in your literature review and in your final project? 8

4.4 How to find and access articles

You should be able to find and access all the relevant articles online. Leafing through bound volumes and photocopying should not be neededs. (Having been a student in the late 90’s and 2000’s, I wish I could get those hours back.)

The old way!

Figure 4.3: The old way!

Good online tools include Jstor (jstor.org) and Google Scholar (scholar.google.co.uk). Your university should have access to Jstor, and Google is accessible to all (although the linked articles may require special access). You will usually have the ‘most access’ when logged into your university or library computing system.If you cannot access a paper, you may want to consult a reference librarian.

It is also ok, if you cannot access the journal article itself, to use the last working paper version (on Google scholar find this in the tab that says “all X versions”, where X is some number, and look for a PDF). However, authors do not always put up the most polished versions, although they should do to promote open-access. As a very last resort, you can e-mail the author and ask him or her to send you the paper.

When looking for references, try to find ones published in respected refereed economics journals (see above ).

4.5 Good starting points: Survey article, course notes, and textbooks

A “survey article” is a good place to start; this is a paper that is largely a categorization and discussion of previous work on a particular topic. You can often find such papers in journals such as

  • the Journal of Economic Perspectives,
  • the Journal of Economic Surveys,
  • and the Journal of Economic Literature.

These will be useful as a “catalog” of papers to read and considers citing. They are also typically very readable and offer a decent introduction to the issue or the field.

It is also helpful to consult module (course) notes and syllabi from the relevant field. Do not only limit yourself to the ones at your own university; many of universities make their course materials publicly accessible online. These will not only typically contain reading lists with well-respected and useful references, they may also contain slides and other material that will help you better understand your topic and the relevant issues.

However, be careful not to take material from course notes without properly citing it. (Better yet, try to find the original paper that the course notes are referring to.)

Textbooks serve as another extremely useful jumping off point. Look through your own textbooks and other textbooks in the right fields. Textbooks draw from, and cite a range of relevant articles and papers. (You may also want to go back to textbooks when you are finding the articles you are reading too difficult. Textbooks may present a simpler version of the material presented in an article, and explain the concepts better.)

4.6 Backwards and forwards with references

When you find a useful paper, look for its “family.” You may want to go back to earlier, more fundamental references, by looking at the articles that this paper cited. See what is listed as “keywords” (these are usually given at the top of the paper), and “JEL codes”. Check what papers this paper cites, and check what other papers cited this paper. On Google scholar you can follow this with a link “Cited by…” below the listed article. “Related articles” is also a useful link.

4.7 Citations

Keep track of all references and citations

You may find it helpful to use software to help you manage your citations

A storage “database” of citations (e.g., Jabref, Zotero, Endnote, Mendeley); these interface well with Google Scholar and Jstor

An automatic “insert citation” and “insert bibliography” in your word processing software

Use a tool like Endnote to manage and insert the bibliographies, or use a bibliography manager software such as Zotero or Jabref,

Further discussion: Citation management tools

List of works cited

Put your list of references in alphabetical order by author’s last name (surname).

Include all articles and works that you cite in your paper; do not include any that you don’t cite.

Avoiding plagiarism and academic offenses**

Here is a definition of plagiarism

The main point is that you need to cite everything that is not your own work. Furthermore, be clear to distinguish what is your own work and your own language and what is from somewhere/someone else.

Why cite? Not just to give credit to others but to make it clear that the remaining uncited content is your own.

Here are some basic rules:

(Rephrased from University of Essex material, as seen in Department of Economics, EC100 Economics for Business Handbook 2017-18, https://www1.essex.ac.uk/economics/documents/EC100-Booklet_2017.pdf accessed on 20 July 2019, pp. 15-16)

Do not submit anything that is not your own work.

Never copy from friends.

Do not copy your own work or previously submitted work. (Caveat: If you are submitting a draft or a ‘literature review and project plan’ at an earlier stage, this can be incorporated into your final submission.

Don’t copy text directly into your work, unless:

  • you put all passages in quotation marks: beginning with ’ and ending with ’, or clearly offset from the main text
  • you cite the source of this text.
It is not sufficient merely to add a citation for the source of copied material following the copied material (typically the end of a paragraph). You must include the copied material in quotation marks. … Ignorance … is no defence.’ (ibid, pp. 15 )

(‘Ibid’ means ‘same as the previous citation’.)

Your university may use sophisticated plagiarism-detection software. Markers may also report if the paper looks suspect

Before final submission, they may ask you to go over your draft and sign that you understand the contents and you have demonstrated that the work is your own.

Not being in touch with your supervisor may put you under suspicion.

Your university may give a Viva Voce oral exam if your work is under suspicion. It is a cool-sounding word but probably something you want to avoid.

Your university may store your work in its our database, and can pursue disciplinary action, even after you have graduated.

Penalties may be severe, including failure with no opportunity to retake the module (course). You may even risk your degree!

Comprehension questions; answers in footnotes

True or false: “If you do not directly quote a paper you do not need to cite it” 9

You should read and cite a paper (choose all that are correct)… 10

  • If it motivates ‘why your question is interesting’ and how it can be modeled economically
  • Only if it asks the same question as your paper
  • Only if it is dealing with the same country/industry/etc as you are addressing
  • If it has any connection to your topic, question, or related matters
  • If it answers a similar question as your paper
  • If it uses and discusses techniques that inform those you are using

4.8 How to write about previous authors’ analysis and findings

Use the right terminology.

“Johnson et al. (2000) provide an analytical framework that sheds substantial doubt on that belief. When trying to obtain a correlation between institutional efficiency and wealth per capita, they are left with largely inconclusive results.”

They are not trying to “obtain a correlation”; they are trying to measure the relationship and test hypotheses.

“Findings”: Critically examine sources

Don’t take everything that is in print (or written online) as gospel truth. Be skeptical and carefully evaluate the arguments and evidence presented. Try to really survey what has been written, to consider the range of opinions and the preponderance of the evidence. You also need to be careful to distinguish between “real research” and propaganda or press releases.

The returns to higher education in Atlantis are extremely high. For the majority of Atlanian students a university degree has increased their lifetime income by over 50%, as reported in the “Benefits of Higher Education” report put out by the Association of Atlantian Universities (2016).

But don’t be harsh without explanation:

Smith (2014) found a return to education in Atlantis exceeding 50%. This result is unlikely to be true because the study was not a very good one.

“Findings:” “They Proved”

A theoretical economic model can not really prove anything about the real world; they typically rely on strong simplifying assumptions.

Through their economic model, they prove that as long as elites have incentives to invest in de facto power, through lobbying or corruption for example, they will invest as much as possible in order to gain favourable conditions in the future for their businesses.
In their two period model, which assumes \[details of key assumptions here\] , they find that when an elite Agent has an incentive to invest in de facto power, he invests a strictly positive amount, up to the point where marginal benefit equals marginal cost”

Empirical work does not “prove” anything (nor does it claim to).

It relies on statistical inference under specific assumptions, and an intuitive sense that evidence from one situation is likely to apply to other situations.

“As Smith et al (1999) proved using data from the 1910-1920 Scandanavian stock exchange, equity prices always increase in response to reductions in corporate tax rates.”
“Smith et al (199) estimated a VAR regression for a dynamic CAP model using data from the 1910-1920 Scandanavian stock exchange. They found a strongly statistically significant negative coefficient on corporate tax rates. This suggests that such taxes may have a negative effect on publicly traded securities. However, as their data was from a limited period with several simultaneous changes in policy, and their results are not robust to \[something here\] , further evidence is needed on this question.”

Use the language of classical 11 statistics:

Hypothesis testing, statistical significance, robustness checks, magnitudes of effects, confidence intervals.

Note that generalisation outside the data depends on an intuitive sense that evidence from one situation is likely to apply to other situations.

“Findings”: How do you (or the cited paper) claim to identify a causal relationship?

This policy was explained by Smith and Johnson (2002) in their research on subsidies and redistribution in higher education. Their results showed that people with higher degree have higher salaries and so pay higher taxes. Thus subsidizing higher education leads to a large social gain.

The results the student discusses seem to show an association between higher degrees and higher salaries. The student seems to imply that the education itself led to higher salaries. This has not been shown by the cited paper. Perhaps people who were able to get into higher education would earn higher salaries anyway. There are ways economists used to try to identify a “causal effect” (by the way, this widely used term is redundant as all effects must have a cause), but a mere association between two variables is not enough

As inflation was systematically lower during periods of recession, we see that too low a level of inflation increases unemployment.

Economists have long debated the nature of this “Phillips curve” relationship. There is much work trying to determine whether the association (to the extent it exists) is a causal one. We could not rule out reverse causality, or third factor that might cause changes in both variables.

4.9 …Stating empirical results

Don’t write: “I accept the null hypothesis.”

Do write: “The results fail to reject the null hypothesis, in spite of a large sample size and an estimate with small standard errors” (if this is the case)

Note: The question of what to infer from acceptance/rejection of null hypotheses is a complex difficult one in Classical (as opposed to Bayesian) statistics. This difficulty is in part philosophical: classical hypothesis testing is deductive , while inference is necessarily inductive.

4.10 What to report

You need to read this paper more clearly; it is not clear what they conclude nor what their evidence is.

4.11 Organising your literature review

A common marking comment:

These papers seem to be discussed in random order – you need some structure organising these papers thematically, by finding, by technique, or chronologically perhaps.

How should you organise it? In what order?

Thematically (usually better)

By method, by theoretical framework, by results or assumptions, by field

Chronologically (perhaps within themes)

Exercise: Compare how the literature review section is organized in papers you are reading.

Organising a set of references

Figure 4.4: Organising a set of references

Q: What sort of structure am I using in the above outline?

It may also be helpful to make a ‘table’ of the relevant literature, as in the figure below. This will help you get a sense of the methods and results, and how the papers relate, and how to assess the evidence. You may end up putting this in the actual paper.

Organisational table from Reinstein and Riener, 2012b

Figure 4.5: Organisational table from Reinstein and Riener, 2012b

4.12 What if you have trouble reading and understanding a paper?

Consult a survey paper, textbook, or lecture notes that discuss this paper and this topic

Try to find an easier related paper

Ask your supervisor for help; if he or she can

Try to understand what you can; do not try to “fake it”

4.13 Some literature survey do’s and don’ts

Do not cite irrelevant literature.

Do not merely list all the papers you could find.

Discuss them, and their relevance to your paper.

What are their strengths and weaknesses? What techniques do they use, and what assumptions do they rely on? How do they relate to each other?

Use correct citation formats.

Try to find original sources (don’t just cite a web link).

Don’t just cut and paste from other sources. And make sure to attribute every source and every quote. Be clear: which part of your paper is your own work and what is cited from others? The penalties for plagiarism can be severe!

  • Critically examine the sources, arguments, and methods

4.14 Comprehension questions: literature review

How to discuss empirical results: “Causal” estimation, e.g., with Instrumental Variables

Which is the best way to state it? 12

“As I prove in table 2, more lawyers lead to slower growth (as demonstrated by the regression analysis evidence).”

“Table 2 provides evidence that a high share of lawyers in a city’s population leads to slower growth.”

3.“Table 2 shows that a high share of lawyers in a city’s population is correlated with slower growth.”

Which is better? 13

  • “However, when a set of observable determinants of city growth (such as Census Region growth) are accounted for, the estimate of this effect becomes less precise.”
  • “In the correct regression I control for all determinants of city growth and find that there is no effect of lawyers on growth”

Stating empirical results: descriptive

“Using the US data from 1850-1950, I find that inflation is lower during periods of recession. This is statistically significant in a t-test [or whatever test] at the 99% level, and the difference is economically meaningful. This is consistent with the theory of …, which predicts that lower inflation increases unemployment. However, other explanations are possible, including reverse causality, and unmeasured covarying lags and trends.”

“I find a significantly lower level of inflation during periods of recession, and the difference is economically meaningful. This relationship is statistically significant and the data is accurately measured. Thus I find that inflation increases unemployment.”

Some tips on writing a good paper– relevant to literature reviews

  • Answer the question
  • Provide clear structure and signposting
  • Demonstrate an ability for critical analysis
  • Refer to your sources
  • Produce a coherent, clear argument
  • Take time to proofread for style and expresssion
  • Source “Assignment Writing Skills EBS 3rd year 2012”"

Structure of a literature review

Determine your purpose.

Work out what you need to address in the literature review. What are you being asked to do in your literature review? What are you searching the literature to discover? Check your assignment question and your criteria sheet to know what to focus on.

Do an extensive search of the literature

Find out what has been written on the topic.

What kind of literature?

Select appropriate source material: Use a variety of academic or scholarly sources that are relevant, current and authoritative. An extensive review of relevant material will include — books, journal articles, reports, government documents, conference proceedings and web resources. The Library would be the best place to search for your sources.

How many resources?

The number of sources that you will be required to review will depend on what the literature review is for and how advanced you are in your studies. It could be from five sources at first year undergraduate level to more than fifty for a thesis. Your lecturer will advise you on these details.

Note the bibliographical details of your sources

Keep a note of the publication title, date, authors’ names, page numbers and publishers. These details will save you time later.

Read the literature

  • Critically read each source, look for the arguments presented rather than for facts.
  • Take notes as you read and start to organise your review around themes and ideas.
  • Consider using a table, matrix or concept map to identify how the different sources relate to each other.

Analyse the literature you have found

In order for your writing to reflect strong critical analysis, you need to evaluate the sources. For each source you are reviewing ask yourself these questions:

  • What are the key terms and concepts?
  • How relevant is this article to my specific topic?
  • What are the major relationships, trends and patterns?
  • How has the author structured the arguments?
  • How authoritative and credible is this source?
  • What are the differences and similarities between the sources?
  • Are there any gaps in the literature that require further study?

Write the review

  • Start by writing your thesis statement. This is an important introductory sentence that will tell your reader what the topic is and the overall perspective or argument you will be presenting.
  • Like essays, a literature review must have an introduction, a body and a conclusion.

Introduction

Your introduction should give an outline of:

  • why you are writing a review, and why the topic is important
  • the scope of the review — what aspects of the topic will be discussed
  • the criteria used for your literature selection (e.g. type of sources used, date range)
  • the organisational pattern of the review.

Body paragraphs

Each body paragraph should deal with a different theme that is relevant to your topic. You will need to synthesise several of your reviewed readings into each paragraph, so that there is a clear connection between the various sources. You will need to critically analyse each source for how they contribute to the themes you are researching.

The body could include paragraphs on:

  • historical background
  • methodologies
  • previous studies on the topic
  • mainstream versus alternative viewpoints
  • principal questions being asked
  • general conclusions that are being drawn.

Your conclusion should give a summary of:

  • the main agreements and disagreements in the literature
  • any gaps or areas for further research
  • your overall perspective on the topic.
  • outlined the purpose and scope?
  • identified appropriate and credible (academic/scholarly) literature?
  • recorded the bibliographical details of the sources?
  • analysed and critiqued your readings?
  • identified gaps in the literature and research?
  • explored methodologies / theories / hypotheses / models?
  • discussed the varying viewpoints?
  • written an introduction, body and conclusion?
  • checked punctuation and spelling?

Literature Review Writing Tips

Synthesize your findings. Your findings are your evaluation of the literature reviewed: what you consider the strengths and weakness of the studies reviewed; the comparison you did between studies; research trends and gaps in the research that you found while researching your topic, etc...

Across the articles that you read, pay attention to what are the:

  • Common/contested findings
  • Important trends
  • Influential theories

Keep this in mind when writing your literature review:

  • Do not over-quote:  If you only quote from every single author you found, then you are not showing any original thinking or analysis. Use quotes judiciously. Use quotes to highlight a particular passage or thought that exemplifies the research, theory or topic you are researching.
  • Instead, use paraphrasing:  Restate the main ideas of a paragraph or section to highlight, in your own words, the important points made by the author.
  • Summarize findings, important sections, a whole article or book: This is different from paraphrasing since you are not re-stating the author's words but summarizing the main point of what you are reading in a concise matter for your readers.

All about citation trails

Welcome! Here we'll discuss citation trails: what they are, how to locate them, and how to use them to improve your research. Sometimes the act of following a citation trail is called "citation chaining" or "citation mining."

After reading this guide and doing the included activity, you should:

  • Define what a citation trail is,
  • Distinguish between forward and backward citation trails are, and
  • Use citation trails to find additional resources for your research.

What is a citation trail?

A citation trail is a link from an article or book to a second article or book, connected in some way to the first article. If you find an article that is important or relevant to your work, you should follow the citation trails to find similarly important or relevant articles .  

A screen capture showing an article with 76 citations in Web of Science

The number of citations an article gets may indicate the relative importance of that article in the field or discipline. Generally, the higher the list of citations, the more that article has been used as a resource for subsequent research, which would suggest that the article's research and conclusions are sound. However, if an article is very recently published (within the last two or three years), it may not have many citations regardless of its value.

This is the last section of the paper. Here you should provide an alphabetical listing of all the published work you cited in the text of the paper. This does not mean every article you found in your research; only include the works you actually cited in the text of your paper. A standard format is used both to cite literature in the text and to list these studies in the Literature Cited section.  Hypothetical examples of the format used in the journal Ecology are below:     Djorjevic, M., D.W. Gabriel and B.G. Rolfe. 1987. Rhizobium: Refined parasite of legumes. Annual Review of Phytopathology 25: 145-168.     Jones, I. J. and B. J. Green. 1963. Inhibitory agents in walnut trees. Plant Physiology 70:101-152.     MacArthur, R.H. and E.O. Wilson. 1967. The Theory of Island Biogeography. Princeton University Press, Princeton, N.J.     Smith, E. A. 1949. Allelopathy in walnuts. American Journal of Botany 35:1066-1071. Here is a dissection of the first entry, in the format for Ecology :       Firstauthor, M., D.W. Secondauthor and B.G. Thirdauthor. Year. Article title with only the first letter capitalized. Journal Article Title with Important Words in Caps  volume#(issue# if there is one): firstpage-lastpage. Notice some of the following details:       - the list is alphabetized;     - no first or middle names are listed (the author's first and middle initials are used instead);     - only the first word in the title of the journal article (except for proper nouns) is capitalized;     - different journals use different styles for Literature Cited sections.   You should pay careful attention to details of formatting when you write your own Literature Cited section. For papers published in journals you must provide the date, title, journal name, volume number, and page numbers. For books you need the publication date, title, publisher, and place of publication.

How to Write a Literature Review? A Beginner’s Guide

Sooner or later in your academic path, you will be required to compose a literature review. So, it’s important to approach this task well-prepared and understand how to write a literature review inside out. 

Are you interested in how to write lit review projects correctly and cover the subject comprehensively, from all angles? This article will explore the concept of review of literature , dwell on how to write a literature review in line with your professor’s expectations, and share a universal literature review template for your usage. 

What Is the Purpose of a Literature Review? 

To understand what should be included in a literature review , you need to understand its purpose and value in a larger work. A well-researched and written lit review usually addresses the following objectives: 

  • Inform . The fundamental purpose of any review of literature is to provide the foundation of knowledge on a specific topic or phenomenon. You explore what people have learned about it from prior studies and summarize those findings to inform your readers. 
  • Give credit . Another purpose of a lit review is to identify researchers who have contributed to the advancement of research on your chosen literature review topic and have produced the most valuable findings. This way, you pay tribute to those researchers and showcase your knowledge of the most considerable influencers. 
  • Identify gaps . By performing a thorough review of literature , you may not only discover what is known about your topic but also find out what it yet to be learned about it. As a result of reviewing the available evidence, you may identify gaps for addressing through your academic inquiry. 
  • Identify patterns . Those who know how to write a literature review can also effectively embrace data trends and patterns in the collected dataset. As a result, they can present a more nuanced analysis of the existing knowledge in your literature review and uncover dependencies that inform people’s understanding of certain phenomena and processes.  
  • Contextualize research . When you perform lit review writing, you can also create a spot for your own study within the broad field of your academic research interest. This way, you show to your readers that you can effectively navigate the landscape of your academic area. 

These purposes lay the foundation for understanding how to write a literature review that will attain all academic goals. You simply need to use this list as your checklist for structuring an impactful lit review and including all vital data in it. 

How to Write a Literature Review? 

Now, we come to the main topic of this article – how to write a good literature review for dissertation projects, research papers, and other works. Follow the steps we’ve covered below to arrive at a consistent, logical piece of lit review . 

Identify Relevant Sources 

Any literature review writing starts with academic research. You should look for sources that explore your topic from various angles and provide valuable literature review findings to expand your knowledge on the subject. It’s best to look for subject-specific books first and then go through academic databases that publish journal articles. This way, you will start with the evidence of the highest reliability level and move on to expand your literature review dataset conveniently. 

Screen Sources for Quality 

The best solution on how to write a literature review without challenges is to rely on high-quality evidence. Your task is to research extensively in reliable academic databases to find peer-reviewed academic journals and books written by experts in your field. Don’t over-rely on online sources in your literature review, like blogs or opinion pieces, because they rarely possess the needed degree of credibility for an academic review. By choosing only industry-approved sources from qualified professionals, you can build a solid foundation for your writing and impress the audience. 

Determine Data Patterns and Gaps 

How to write a literature review of value for your readers? One of the best approaches is to go beyond mere summarization of what other researchers have found on the subject and to apply critical thinking and data categorization. This way, you will manage to uncover existing patterns and trends and examine those dependencies in your literature review. A systematic, critical approach is always evaluated much higher than a simple outline of what people say on your subject. 

Draft an Outline 

Now, it’s time to compose an outline for a literature review . The outline should include the main concepts you’re planning to cover in the literature review text and should structure the narrative consistently. By means of composing an outline before the actual writing process, you give yourself a hands-on roadmap for composing a logically flowing piece. As a result of using an outline, you will write the literature review faster and will avoid the risk of going off-topic. 

Compose the Review 

With a good and detailed outline, you should have no more problems or concerns about how to write a literature review . The writing process should go quickly and smoothly when you have all your evidence at your fingertips, categorized by themes and requiring only proper summarization in the text. 

We recommend starting with a broad introduction to the topic and concepts related to it. You should give definitions and explain the topic’s features and components that require attention in the research process. After that, you may briefly outline the main sections of your review and then proceed to the exploration of each section in depth. 

At times, your professor will give you a specific structure for review writing – such as the general introduction, coverage of theories, and then coverage of empirical evidence. At times, it may be a review of the data search strategy and a report on the identified resources that follow. In any case, you should follow the tutor’s prompt closely to ensure compliance with the task. 

Make Use of This Generic Literature Review Template 

Looking for a universal, ready-to-use literature review template ? Here is an effective literature review template that everyone can apply with minor tweaks to produce a high-quality review of literature . 

LITERATURE REVIEW TEMPLATE 

Introduction 

  • Introduce the topic of your literature review 
  • Examine its significance for your academic area 
  • Determine the scope of your literature review inquiry 
  • Give a brief outline of subtopics and sections included in your literature review 

Body of the literature review

  • Describe the subtopic and indicate how it relates to your literature review’s main idea
  • Summarize the evidence available about it 
  • Compare the available data and voice your opinion 

Conclusion 

  • Summarize the main points and findings from your literature review 
  • State the main contribution you have managed to achieve 
  • Identify the research gaps your literature review has revealed 

Use this literature review template to pump your writing muscle and get ready for new literature review challenges. 

More Pro Tips for Writing a Literature Review 

If you’re still unsure about how to do a literature review with excellence, these pro tips may improve your understanding of this task type. 

  • Mind the audience . Understanding how to do a literature review for a research paper often has little to do with how to write literature review for thesis . This difference is explained by the fact that these types of academic work are of different lengths and pursue different scholarly goals. This way, you may need to cover only some basic seminal research in the review of literature for a research paper but will need to dig deeper into theoretical and applied research with deeper analysis and more critical thinking when dealing with a thesis.
  • Mind the length . How long should a literature review be ? This is a vital question that you should answer before starting the outlining and writing process. Ask your professor if you’re not sure or apply the rule of thumb, where this section usually takes from 15% to 25% of the entire paper. 
  • Mind the structure . It’s important to cover all lit review aspects that your professor wants to see in the paper; otherwise, you risk getting a low grade even if your literature review is comprehensive and interesting. What should a literature review include ? In most cases, you will be required to cover some seminal research works in your literature review to show that you understand who the pioneers in the field are, and what contribution they have made to the topic’s exploration. Next, you should examine relevant theories that inform studies in your subject. At the end of the literature review, you should typically cite a variety of studies of applied nature, thus showing what empirical research is conducted in your academic field.  

With these recommendations at your disposal, you’re sure to become much more proficient in how to do a lit review .
