Parenthetical citations:  (Grady et al., 2019; Jerrentrup et al., 2018)

Narrative citations:  Grady et al. (2019) and Jerrentrup et al. (2018)

• If a journal article has a DOI, include the DOI in the reference.
• If the journal article does not have a DOI and is from an academic research database, end the reference after the page range (for an explanation of why, see the  database information  page). The reference in this case is the same as for a print journal article.
• Do not include database information in the reference unless the journal article comes from a database that publishes original, proprietary content, such as UpToDate (see an example on the  database information  page).
• If the journal article does not have a DOI but does have a URL that will resolve for readers (e.g., it is from an online journal that is not part of a database), include the URL of the article at the end of the reference.
• If the journal article has an article number instead of a page range, include the article number instead of the page range (as shown in the Jerrentrup et al. example).

Parenthetical citations:  (Rabinowitz, 2019; Sapolsky, 2017)

Narrative citations:  Rabinowitz (2019) and Sapolsky (2017)

• If the book includes a DOI, include the DOI in the reference after the publisher name.
• Do not include the publisher location.
• If the book does not have a DOI and comes from an academic research database, end the book reference after the publisher name. Do not include  database information  in the reference. The reference in this case is the same as for a print book.

Parenthetical citations:  (Schaefer & Shapiro, 2019; Schulman, 2019)

Narrative citations:  Schaefer and Shapiro (2019) and Schulman (2019)

• If a magazine article has a DOI, include the DOI in the reference.
• If the magazine article does not have a DOI and is from an academic research database, end the reference after the page range. Do not include  database information  in the reference. The reference in this case is the same as for a print magazine article.
• If the magazine article does not have a DOI but does have a URL that will resolve for readers (e.g., it is from an online magazine that is not part of a database), include the URL of the article at the end of the reference.
• If the magazine article does not have volume, issue, and/or page numbers (e.g., because it is from an online magazine), omit the missing elements from the reference (as in the Schulman example).

Parenthetical citation:  (Carey, 2019)

Narrative citation:  Carey (2019)

• If the newspaper article is from an academic research database, end the reference after the page range. Do not include  database information  in the reference. The reference in this case is the same as for a print newspaper article.
• If the newspaper article has a URL that will resolve for readers (e.g., it is from an online newspaper), include the URL of the article at the end of the reference.
• If the newspaper article does not have volume, issue, and/or page numbers (e.g., because it is from an online newspaper), omit the missing elements from the reference, as shown in the example.
• If the article is from a news website (e.g., CNN, HuffPost)—one that does not have an associated daily or weekly newspaper—use the format for a  webpage on a website  instead.

Parenthetical citation:  (Aron et al., 2019)

Narrative citation:  Aron et al. (2019)

• If the edited book chapter includes a DOI, include the chapter DOI in the reference after the publisher name.
• If the edited book chapter does not have a DOI and comes from an academic research database, end the edited book chapter reference after the publisher name. Do not include  database information  in the reference. The reference in this case is the same as for a print edited book chapter.
• Do not create references for chapters of authored books. Instead, write a reference for the whole book and cite the chapter in the text if desired (e.g., Kumar, 2017, Chapter 2).

Parenthetical citation:  (Merriam-Webster, n.d.)

Narrative citation:  Merriam-Webster (n.d.)

• Because entries in  Merriam-Webster’s Dictionary  are updated over time and are not archived, include a  retrieval date  in the reference.
• Merriam-Webster is both the author and the publisher, so the name appears in the author element only to avoid repetition.
• To quote a dictionary definition, view the pages on quotations and  how to quote works without page numbers  for guidance. Additionally, here is an example:  Culture  refers to the “customary beliefs, social forms, and material traits of a racial, religious, or social group” (Merriam-Webster, n.d., Definition 1a).

Parenthetical citation:  (National Cancer Institute, 2019)

Narrative citation:  National Cancer Institute (2019)

The specific agency responsible for the report appears as the author. The names of parent agencies not present in the  group author name  appear in the source element as the publisher. This creates concise in-text citations and complete reference list entries.

Parenthetical citation:  (Harvard University, 2019)

Narrative citation:  Harvard University (2019)

• Use the name of the account that uploaded the video as the author.
• If the account did not actually create the work, explain this in the text if it is important for readers to know. However, if that would mean citing a source that appears unauthoritative, you might also look for the author’s YouTube channel, official website, or other social media to see whether the same video is available elsewhere.

Parenthetical citations:  (APA Databases, 2019; Gates, 2019)

Narrative citations:  APA Databases (2019) and Gates (2019)

• Present the name of the individual or group author the same as you would for any other reference. Then provide the Twitter handle (beginning with the @ sign) in square brackets, followed by a period.
• Provide the first 20 words of the tweet as the title. Count a URL, a hashtag, or an emoji as one word each, and include them in the reference if they fall within the first 20 words.
• If the tweet includes an image, a video, a poll, or a thumbnail image with a link, indicate that in brackets after the title: [Image attached], [Video attached], [Thumbnail with link attached].
• The same format used for Twitter is also used for Instagram.  

Parenthetical citation:  (News From Science, 2019)

Narrative citation:  News From Science (2019)

• Provide the first 20 words of the Facebook post as the title. Count a URL or other link, a hashtag, or an emoji as one word each, and include them in the reference if they fall within the first 20 words. 
• If a status update includes images, videos, thumbnail links to outside sources, or content from another Facebook post (such as when sharing a link), indicate that in square brackets.

Parenthetical citations:  (Fagan, 2019; National Institute of Mental Health, 2018; Woodyatt, 2019; World Health Organization, 2018)

Narrative citations:  Fagan (2019), National Institute of Mental Health (2018), Woodyatt (2019), and World Health Organization (2018)

• Provide as specific a  date  as is available on the webpage. This might be a year only; a year and month; or a year, month, and day.
• Italicize the title of a webpage.
• When the author of the webpage and the publisher of the website are the same, omit the publisher name to avoid repetition (as in the World Health Organization example).
• When contents of a page are meant to be updated over time but are not archived, include a  retrieval date  in the reference (as in the Fagan example).
• Use the webpage on a website format for articles from news websites such as CNN and HuffPost (these sites do not have associated daily or weekly newspapers). Use the  newspaper article category  for articles from newspaper websites such as  The New York Times  or  The Washington Post .
• Create a reference to an open educational resources (OER) page only when the materials are available for download directly (i.e., the materials are on the page and/or can be downloaded as PDFs or other files). If you are directed to another website, create a reference to the specific webpage on that website where the materials can be retrieved. Use this format for material in any OER repository, such as OER Commons, OASIS, or MERLOT.
• Do not create a reference or in-text citation for a whole website. To mention a website in general, and not any particular information on that site, provide the name of the website in the text and include the URL in parentheses. For example, you might mention that you used a website to create a survey.

The following supplemental example references are mention in the  Publication Manual:

• retracted journal or magazine article
• edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM)
• edition of the International Statistical Classification of Diseases and Related Health Problems (ICD)
• religious work
• annotated religious work

Archival document and collections are not presented in the  APA Publication Manual, Seventh Edition . This content is available only on the APA Style website .  This guidance has been expanded from the 6th edition.

Archival sources include letters, unpublished manuscripts, limited-circulation brochures and pamphlets, in-house institutional and corporate documents, clippings, and other documents, as well as such nontextual materials as photographs and apparatus, that are in the personal possession of an author, form part of an institutional collection, or are stored in an archive such as the Archives of the History of American Psychology at the University of Akron or the APA Archives. For any documents like these that are available on the open web or via a database (subscription or nonsubscription), follow the reference templates shown in Chapter 10 of the Publication Manual.

The general format for the reference for an archival work includes the author, date, title, and source. The reference examples shown on this page may be modified for collections requiring more or less specific information to locate materials, for different types of collections, or for additional descriptive information (e.g., a translation of a letter). Authors may choose to list correspondence from their own personal collections, but correspondence from other private collections should be listed only with the permission of the collector.

Keep in mind the following principles when creating references to archival documents and collections:

• As with any reference, the purpose is to direct readers to the source, despite the fact that only a single copy of the document may be available and readers may have some difficulty actually seeing a copy.
• Include as much information as is needed to help locate the item with reasonable ease within the repository. For items from collections with detailed finding aids, the name of the collection may be sufficient; for items from collections without finding aids, more information (e.g., call number, box number, file name or number) may be necessary to help locate the item.
• If several letters are cited from the same collection, list the collection as a reference and provide specific identifying information (author, recipient, and date) for each letter in the in-text citations (see Example 3).
• Use square brackets to indicate information that does not appear on the document.
• Use “ca.” (circa) to indicate an estimated date (see Example 5).
• Use italics for titles of archival documents and collections; if the work does not have a title, provide a description in square brackets without italics.
• Separate elements of the source (e.g., the name of a repository, library, university or archive, and the location of the university or archive) with commas. End the source with a period.
• If a publication of limited circulation is available in libraries, the reference may be formatted as usual for published material, without the archival source.
• Note that private letters (vs. those in an archive or repository) are considered personal communications and cited in the text only.

Read the full APA guidelines on citing ChatGPT 

OpenAI. (2023).  ChatGPT  (Mar 14 version) [Large language model].  https://chat.openai.com/chat

• Parenthetical citation:  (OpenAI, 2023)
• Narrative citation:  OpenAI (2023)

Author:  The author of the model is OpenAI.

Date:  The date is the year of the version you used. Following the template in Section 10.10, you need to include only the year, not the exact date. The version number provides the specific date information a reader might need.

Title:  The name of the model is “ChatGPT,” so that serves as the title and is italicized in your reference, as shown in the template. Although OpenAI labels unique iterations (i.e., ChatGPT-3, ChatGPT-4), they are using “ChatGPT” as the general name of the model, with updates identified with version numbers.

The version number is included after the title in parentheses. The format for the version number in ChatGPT references includes the date because that is how OpenAI is labeling the versions. Different large language models or software might use different version numbering; use the version number in the format the author or publisher provides, which may be a numbering system (e.g., Version 2.0) or other methods.

Bracketed text  is used in references for additional descriptions when they are needed to help a reader understand what’s being cited. References for a number of common sources, such as journal articles and books, do not include bracketed descriptions, but things outside of the typical peer-reviewed system often do. In the case of a reference for ChatGPT, provide the descriptor “Large language model” in square brackets. OpenAI describes ChatGPT-4 as a “large multimodal model,” so that description may be provided instead if you are using ChatGPT-4. Later versions and software or models from other companies may need different descriptions, based on how the publishers describe the model. The goal of the bracketed text is to briefly describe the kind of model to your reader.

Source:  When the publisher name and the author name are the same, do not repeat the publisher name in the source element of the reference, and move directly to the URL. This is the case for ChatGPT. The URL for ChatGPT is  https://chat.openai.com/chat . For other models or products for which you may create a reference, use the URL that links as directly as possible to the source (i.e., the page where you can access the model, not the publisher’s homepage).

What to include and what to exclude

Works included in a reference list.

The reference list provides a reliable way for readers to identify and locate the works cited in a paper. APA Style papers generally include reference lists, not  bibliographies.

In general, each work cited in the text must appear in the reference list, and each work in the reference list must be cited in the text. Check your work carefully before submitting your manuscript or course assignment to ensure no works cited in the text are missing from the reference list and vice versa, with only the following exceptions.

Works Excluded From a Reference List

There are a few kinds of works that are not included in a reference list. Usually a work is not included because readers cannot recover it or because the mention is so broad that readers do not need a reference list entry to understand the use.

Information on works included in a reference list is covered in Sections 2.12 and 8.4 of the  APA Publication Manual, Seventh Edition

*This guidance has been expanded from the 6th edition.*

• Personal communications  such as emails, phone calls, or text messages are cited in the text only, not in the reference list, because readers cannot retrieve personal communications.
• General mentions of whole websites, whole periodicals, and common software and apps in the text do not require in-text citations or reference list entries because the use is broad and the source is familiar.
• The source of an epigraph does not usually appear in the reference list unless the work is a scholarly book or journal. For example, if you open the paper with an inspirational quotation by a famous person, the source of the quotation does not appear in the reference list because the quotation is meant to set the stage for the work, not substantiate a key point.   
• Quotations from research participants in a study you conducted can be presented and discussed in the text but do not need citations or reference list entries. Citations and reference list entries are not necessary because the quotations are part of your original research. They could also compromise participants’ confidentiality, which is an ethical violation.
• References included in a meta-analysis, which are marked with an asterisk in the reference list, may be cited in the text (or not) at the author’s discretion. This exception is relevant only to authors who are conducting a meta-analysis.

DOIs and URLs

The DOI or URL is the final component of a reference list entry. Because so much scholarship is available and/or retrieved online, most reference list entries end with either a DOI or a URL.

• A DOI is a unique alphanumeric string that identifies content and provides a persistent link to its location on the internet. DOIs can be found in database records and the reference lists of published works.
• A URL specifies the location of digital information on the internet and can be found in the address bar of your internet browser. URLs in references should link directly to the cited work when possible.

Follow these guidelines for including DOIs and URLs in references:

• Include a DOI for all works that have a DOI, regardless of whether you used the online version or the print version.
• If a print work does not have a DOI, do not include any DOI or URL in the reference.
• If an online work has both a DOI and a URL, include only the DOI.
• For works without DOIs from websites (not including academic research databases), provide a URL in the reference (as long as the URL will work for readers).
• For works without DOIs from most  academic research databases , do not include a URL or database information in the reference because these works are widely available. The reference should be the same as the reference for a print version of the work.
• For works from databases that publish original, proprietary material available only in that database (such as the UpToDate database) or for works of limited circulation in databases (such as monographs in the ERIC database), include the name of the database or archive and the URL of the work. If the URL requires a login or is session-specific (meaning it will not resolve for readers), provide the URL of the database or archive home page or login page instead of the URL for the work. See the page on including  database information in references  for more information. 
• If the URL is no longer working or no longer provides readers access to the content you intend to cite, follow the guidance for works with  no source .
• Other alphanumeric identifiers such as the International Standard Book Number (ISBN) and the International Standard Serial Number (ISSN) are not included in APA Style references.

Follow these guidelines to format DOIs and URLs:

• Present both DOIs and URLs as hyperlinks (i.e., beginning with “http:” or “https:”).
• Because a hyperlink leads readers directly to the content, it is not necessary to include the words “Retrieved from” or “Accessed from” before a DOI or URL.
• It is acceptable to use either the default display settings for hyperlinks in your word-processing program (e.g., usually blue font, underlined) or plain text that is not underlined.
• Leave links live if the work is to be published or read online.
• Follow the current recommendations of the International DOI Foundation to format DOIs in the reference list, which as of this publication is as follows:

https://doi.org/ xxxxx

• The string “https://doi.org/” is a way of presenting a DOI as a link, and “xxxxx” refers to the DOI number.
• The preferred format of the DOI has changed over time. Although older works use previous formats (e.g., “http:/dx.doi.org/” or “doi:” or “DOI:” before the DOI number), in your reference list, standardize DOIs into the current preferred format for all entries. For example, use  https://doi.org/10.1037/a0040251  in your reference even though that article, published in 2016, presented the number in an older format.
• Copy and paste the DOI or URL from your web browser directly into your reference list to avoid transcription errors. Do not change the capitalization or punctuation of the DOI or URL. Do not add line breaks manually to the hyperlink; it is acceptable if your word-processing program automatically adds a break or moves the hyperlink to its own line.
• Do not add a period after the DOI or URL because this may interfere with link functionality.

When a DOI or URL is long or complex, you may use shortDOIs or shortened URLs if desired.

• Use the  shortDOI service  provided by the International DOI Foundation to create shortDOIs. A work can have only one DOI and only one shortDOI; the shortDOI service will either produce a new shortDOI for a work that has never had one or retrieve an existing shortDOI.
• Some websites provide their own branded shortened URLs, and independent URL shortening services are available as well. Any shortened URL is acceptable in a reference as long as you check the link to ensure that it takes you to the correct location.

A Quick Guide to Harvard Referencing | Citation Examples

Published on 14 February 2020 by Jack Caulfield . Revised on 15 September 2023.

Referencing is an important part of academic writing. It tells your readers what sources you’ve used and how to find them.

Harvard is the most common referencing style used in UK universities. In Harvard style, the author and year are cited in-text, and full details of the source are given in a reference list .

Harvard in-text citation, creating a harvard reference list, harvard referencing examples, referencing sources with no author or date, frequently asked questions about harvard referencing.

A Harvard in-text citation appears in brackets beside any quotation or paraphrase of a source. It gives the last name of the author(s) and the year of publication, as well as a page number or range locating the passage referenced, if applicable:

Note that ‘p.’ is used for a single page, ‘pp.’ for multiple pages (e.g. ‘pp. 1–5’).

An in-text citation usually appears immediately after the quotation or paraphrase in question. It may also appear at the end of the relevant sentence, as long as it’s clear what it refers to.

When your sentence already mentions the name of the author, it should not be repeated in the citation:

Sources with multiple authors

When you cite a source with up to three authors, cite all authors’ names. For four or more authors, list only the first name, followed by ‘ et al. ’:

Sources with no page numbers

Some sources, such as websites , often don’t have page numbers. If the source is a short text, you can simply leave out the page number. With longer sources, you can use an alternate locator such as a subheading or paragraph number if you need to specify where to find the quote:

Multiple citations at the same point

When you need multiple citations to appear at the same point in your text – for example, when you refer to several sources with one phrase – you can present them in the same set of brackets, separated by semicolons. List them in order of publication date:

Multiple sources with the same author and date

If you cite multiple sources by the same author which were published in the same year, it’s important to distinguish between them in your citations. To do this, insert an ‘a’ after the year in the first one you reference, a ‘b’ in the second, and so on:

Prevent plagiarism, run a free check.

A bibliography or reference list appears at the end of your text. It lists all your sources in alphabetical order by the author’s last name, giving complete information so that the reader can look them up if necessary.

The reference entry starts with the author’s last name followed by initial(s). Only the first word of the title is capitalised (as well as any proper nouns).

Sources with multiple authors in the reference list

As with in-text citations, up to three authors should be listed; when there are four or more, list only the first author followed by ‘ et al. ’:

Reference list entries vary according to source type, since different information is relevant for different sources. Formats and examples for the most commonly used source types are given below.

• Entire book
• Book chapter
• Translated book
• Edition of a book

Journal articles

• Print journal
• Online-only journal with DOI
• Online-only journal with no DOI
• General web page
• Online article or blog
• Social media post

Sometimes you won’t have all the information you need for a reference. This section covers what to do when a source lacks a publication date or named author.

No publication date

When a source doesn’t have a clear publication date – for example, a constantly updated reference source like Wikipedia or an obscure historical document which can’t be accurately dated – you can replace it with the words ‘no date’:

Note that when you do this with an online source, you should still include an access date, as in the example.

When a source lacks a clearly identified author, there’s often an appropriate corporate source – the organisation responsible for the source – whom you can credit as author instead, as in the Google and Wikipedia examples above.

When that’s not the case, you can just replace it with the title of the source in both the in-text citation and the reference list:

Harvard referencing uses an author–date system. Sources are cited by the author’s last name and the publication year in brackets. Each Harvard in-text citation corresponds to an entry in the alphabetised reference list at the end of the paper.

Vancouver referencing uses a numerical system. Sources are cited by a number in parentheses or superscript. Each number corresponds to a full reference at the end of the paper.

A Harvard in-text citation should appear in brackets every time you quote, paraphrase, or refer to information from a source.

The citation can appear immediately after the quotation or paraphrase, or at the end of the sentence. If you’re quoting, place the citation outside of the quotation marks but before any other punctuation like a comma or full stop.

In Harvard referencing, up to three author names are included in an in-text citation or reference list entry. When there are four or more authors, include only the first, followed by ‘ et al. ’

Though the terms are sometimes used interchangeably, there is a difference in meaning:

• A reference list only includes sources cited in the text – every entry corresponds to an in-text citation .
• A bibliography also includes other sources which were consulted during the research but not cited.

How to Format a Citation

Examples of apa, mla, and chicago manual of style, citation styles: american psychological association (apa), citation styles: chicago, citation styles: modern language association (mla), example: direct quote cited in a book, example: reference within a journal article.

• EndNote This link opens in a new window
• Compare Citation Management Software

There are two basic approaches to citation:

• In-text citations + a list of references at the end of the paper
• Endnotes or footnotes +/- a bibliography at the end of the paper

Scholars writing in the sciences and social sciences typically use in-text citations, while humanities scholars utilize endnotes/footnotes.

While the two basic approaches to citations are simple, there are many different citation styles.

What is a citation style?

The way that citations appear (format) depends on the citation style, which is a set of established rules and conventions for documenting sources.

Citation styles can be defined by an association, such as the Modern Language Association (MLA), publisher, such as the University of Chicago Press, or journal, such as The New England Journal of Medicine .

What citation style should I use?

The citation style that you use depends on the discipline in which you are writing, and where, or by whom, your work will be published or read.

When in doubt, ask your professor if there is a particular style that he/she would like you to use. 

Where can I find more information on how to cite a specific type of source in a particular style?

The library has style manuals in print and online for several commonly used styles such as American Psychological Association (APA), Modern Language Association (MLA) and Chicago.  In addition, there are several excellent citation style guides on the web. (See below)

The basics of apa.

We’re going to start from the beginning for all of you newbies out there, or for those of you looking for a refresher.

APA is an abbreviation which stands for American Psychological Association. This is a massive organization, responsible for creating and sharing psychology-related publications, research, and databases.

Basically, they keep psychologists and other similar roles in the loop with what’s happening in the world of psychology. With close to 120,000 members, this is THE leading world organization related to psychology.They are not officially associated with this guide, but the information here talks about their citing format and rules in depth.

Why were APA citations created and why did my teacher ask me to use this style?

Are you scratching your head, wondering what is APA style is and how this all relates to your research project? To make a long story short, the American Psychological Association did something really cool. Back in 1952, they created a way for ALL psychology researchers to structure their citations. This standard method did three things:

• Psychology researchers were all able to display the sources they used in a systematic way.
• Readers were able to easily understand the information shown in citations.
• There was enough information displayed in the citations for readers to go out and find the exact sources on their own.

APA citations were such a hit, they were so good, that other science disciplines soon adopted the citation format as well. In fact, other disciplines outside of the science world use APA style today, too. So, whether you’re creating a psychology-related research project or not, there’s a good chance you were asked to create your citations in APA style.

Currently in its 7th edition, the Publication Manual of the American Psychological Association is one of the most frequently used style guides for academic writing today!

With the 7th edition just coming onto the scene in 2020, the American Psychological Association does not expect to see widespread usage of the 7th edition until later in 2020. This is why you should always double-check with your teacher on whether they want you to use the 6th edition or the 7th edition for your projects.

Click here for more basics on this style.

Another widely used style is MLA format . Believe it or not, there are thousands of other styles, so perhaps your teacher or professor requested a completely different one. If you’re in that boat, head to EasyBib.com to check out more styles . While you’re at it, poke around and check out our APA reference generator. It may be just what you’re looking for.

References vs. Citations – What’s the difference?

References and citations are two terms that are thrown around a lot and quite often mean the same thing. A reference, or citation, shows the reader that a piece of information originated elsewhere. But, along came APA and decided to throw a curveball at us. In APA, the two terms have two different meanings.

A citation is found in the actual writing of an APA research paper.

In-text citation example:

“Lecture-rooms are numerous and large, but the number of young people who genuinely thirst after truth and justice is small” (Einstein, 2007, p. 5).

A reference is found on the reference page, which is the last page of a research paper. 

Reference Page Example:

Einstein, A. (2007). The world as I see it. Google Books. https://books.google.com/books?id=aNKOo94tO6cC&source=gbs_navlinks_s (Original work published 1934)

The information included in an APA citation is just a snapshot of the information found in the full reference. For more information on when it’s appropriate to include a citation in your paper, head to section 8.1-8.10 of the Publication manual.

Now, what makes things even trickier is that most teachers and professors use the term “APA citations” when they’re actually talking about the full references. How many times have you heard your teacher say, “Make sure you have your citations on the last page!”

Eek! So, to stay on the same page as your teacher, this guide shows you how to make references for an APA reference page, but we’re calling the page “APA Citations.” Someone’s gotta give in, right? Looks like it’s us.

If you’re looking for a quick read on the citations found in the body of the paper, check out our APA Parenthetical Citation page. It’s just one of the many free APA citation guides available on EasyBib.com. Need an APA citation generator? You can find one at EasyBib.com as well!

A rundown on references

Before we get into the nitty-gritty details on how to structure references for your APA paper, let’s get one more quick piece of information off the table.

References are added to research papers and projects only when a source is included in the writing itself.

We don’t add references to a reference page if we want to simply suggest other, similar titles. No! We create references when an actual piece of information from another source is added into the project.

Does your paper include a piece of data from a report? Great! You copied a line of text from a case study and put it in your project (with quotation marks around it)? Perfect! You included a bar graph you found in a brochure? Fantastic! Make sure you create an APA citation in the text of your paper and include the reference on the final page.

The only exception to the above rule is if you’re creating an “annotated bibliography.” For more on that, check out our APA annotated bibliography page.

In case you were wondering, the same goes for MLA in-text & parenthetical citations on the MLA works cited page.

Ready to get started? The next section of the guide is going to explain, step-by-step, how to structure every nook and cranny of your references.

But, if you’re dreaming of an APA citation maker to help make the pain go away from building your references from scratch, you’re in luck. EasyBib.com has an APA citation maker! In just a few clicks, our technology structures and styles each and every APA citation for you. If you don’t know much about it, head to the EasyBib homepage to learn more.

Fundamentals of an APA citation

This entire section goes into detail on each component of a reference. If you’re looking to learn how to style the names of the authors, the title, publishing information, and other aspects related to the reference, this section is for you!

If you want to skip the small talk and see an APA style paper example, go to the “Citation Resources” menu on this page and select “APA Format Guide.” It includes a title page example, an APA paper example, and an APA reference page example.It’s all there for you and the best part about it is it’s free! Do yourself a favor and take a peek at it now!

Author information

The very first piece of information in most references is the author’s name(s). We say “most,” because some sources may not have an author (such as websites, the Bible…). If your source doesn’t have an author, do not include any information about an author in your reference.

Citing a Source with 1 Author

Apa structure:.

Last name of the Author, First initial. Middle initial.

APA Example:

To see some examples, scroll down to the bottom half of this page.

Citing a Source with 2 Authors

Does your source have two authors? Do not put the names in alphabetical order. They should be written in the order they’re displayed on the source.

Last name of the 1st listed Author, First Initial. Middle Initial., & Last name of the 2nd listed Author, First initial. Middle initial.

Doe, J. B. & Chen, W. I.

For an example of a reference with two authors according to the 7th edition of the Publication manual , scroll down to the “Journal Articles found in Print” section, or check out section 9.7-9.12 in the Publication manual.

Citing a Source with 3 to 20 Authors

Does your source have three to twenty authors? The American Psychological Association has made some updates on how to list multiple authors in your citations. If you have between three to twenty authors, list all the authors names (Last Name, Initials). Put them in the same order they’re listed in the source. Commas separate names, and put an ampersand right before the last name.

Bos, G., Hajek, S., Kogman-Appel, K., & Mensching, G. (2019). A Glossary of Latin and Italo-Romance Medico-Botanical Terms in Hebrew Characters on an Illustrated Manuscript Page (Ms. Oxford, Bodleian Opp. 688, fol. 177b). Aleph: Historical Studies in Science and Judaism 19 (2), 169-199. https://www.muse.jhu.edu/article/747571

Citing a Source with 21+ Authors

If your source has over twenty authors, list the last name and initials of the first 19 authors, placing a comma between each name. After the name of the 19th author, use an ellipsis in place of the remaining authors’ names. Then, list the final author’s name in front of it.

Here’s a formatting example for 21+ names using the U.S. presidents (this is NOT a reference example):

Washington, G., Adams, J., Jefferson, T., Madison, J., Monroe, J., Adams, J. Q., Jackson, A., Van Buren, M., Harrison, W. H., Tyler, J., Polk, J., Taylor, Z., Fillmore, M., Pierce, F., Buchanan, J., Lincoln, A., Johnson, A., Grant, U. S., Hayes, R. B., … Trump, D. J.

Citing an Author that is an organization or company

If your source is written by an organization or company:

Some sources are written and released by companies, not necessarily individual people. For example, most brochures at museums only display the institution’s name. Advertisements also only show the company’s name. If the source you’re attempting to cite only shows a group or organization’s name, place it in the reference in the place you’d normally include an individual person’s name.

Write out the name of the group in full; do not use abbreviations. For example, it may seem okay to use USDA, but APA writing style prefers you write out United States Department of Agriculture.

If you’re looking for information on how to style your own name in APA headings, find the example paper on EasyBib.com.

Formatting Titles & Dates

Formatting the date of publication.

The date the source was published is the next item shown in a reference. It’s directly after the author’s name.

For the majority of sources, include only the year in parentheses.

If you’re citing an article in a magazine, include the year and the month.

Peterzell, J. (1990, April). Better late than never. Time, 135 (17), 20–21.

Check out the examples towards the bottom of the page, or head to sections 9.13-9.17 of the Publication manual to see how dates are displayed.

Title rules and capitalization

Titles are the next piece of information shown in a reference. Titles are often tricky for people to style. Students often wonder, “Should I type out the title as it’s shown on the source?” “Should the title be written in italics or underlined?” Here are the answers to (hopefully) all of your title-related questions:

Which letters are capitalized?

Most titles are written with a capital letter in these places:

• At the beginning of the title
• At the beginning of a proper noun
• At the beginning of the subtitle

It may be tempting to write the title as you see it shown on the source, or with capital letters at the beginning of every important word, but that’s not how APA referencing does it.

Here are a few examples of proper lettering:

• A star is born
• Spider-Man: Into the spiderverse
• Harry Potter and the deathly hallows

The only source types that are written with a capital letter at the beginning of every important word are periodicals. Some examples include the titles of newspapers, journals, and magazines.

• The New York Times
• School Library Journal,

How should I style the title?

• Anything that stands alone is written in italics. When we say “stands alone,” we mean it isn’t part of a larger collection. Most books are a single source, so they’re written in italics. Other examples include movies, brochures, dissertations, and music albums.
• Sources that are part of a collection are written without italics. Website pages, journal articles, chapters in books, and individual songs (from an album) are written without italics.
• Remember, the styling information above is for the APA reference page only! Citations in the text of the paper are styled differently. If you need to see a full APA sample paper, check out the other resources on EasyBib.com!

Check out some of the examples below to see how the titles are typed out and styled. You can also head to section 9.18-9.22 of the Publication Manual for more details

If it’s not the actual title, but an APA title page for your paper that you need help with, check out the Title Page APA creator on the homepage of EasyBib.com! Or, check out the main guide for this style, which includes an APA cover page template.

Additional information about a source

It can be difficult to understand a source type just by looking at an APA style citation. Sometimes it isn’t clear if you’re looking at a citation for a presentation, a blog post, lecture notes, or a completely different source type.

To clear up any confusion for your reader, you can include additional information directly after the title. This additional information about the source type is written in brackets with the first word having a capital letter.

Wilson, T. V. & Frey, H. (2019, May 13). Godzilla: The start of his story [Audio podcast]. iHeart Radio. https://www.missedinhistory.com/podcasts/godzilla-the-start-of-his-story.htm

Thanks to the information in the brackets, the reader can easily see that the source is an audio podcast.

Check out the various examples towards the bottom of this page.

Publication information

Publication information includes the name of the publisher. In most cases, the publication information is only included for print sources. Check out the book reference below to see the publication information in action.

Citing a chapter in an edited book in print in APA

An edited book is one that was compiled by an author. Each individual chapter, or section, is written by someone else. Since you’re probably citing the specific chapter, rather than the whole entire book, place the name of the chapter’s author in the first position.

Citing The Bible in APA

Since the bible is considered a “classical work,” and widely known, it is not necessary to create a full reference. Only include a citation in the text of the paper.

Two items need to be included:

• The title and version of the source, such as the New Living Bible
• The names, verses, chapters, or any numbers associated with the section you’re referring to.

“Then the king asked her, “What do you want, Esther? What is your request? I will give it to you, even if it’s half the kingdom” (Esther 5:5 New Living Translation).

Citing a Source on the Internet in APA

Citing digital sources in this style is much easier than other styles. If you’re wondering why, it’s because a lot of information isn’t included in the reference.

For most digital sources, only five items are usually needed:

• The name of the author
• The date the source was published
• The title of the source
• The medium (blog post, audio file, pdf, etc.)
• The website address

Here’s some more information related to web content:

• Only include the medium if it’s unique or if it will help the reader understand the source type.
• Include the website address at the end of the citation.
• Do not place a period at the end of the website address.

Have a digital source? Need to cite APA? Check out some of the examples below.

Citing online encyclopedias & dictionaries – Group author

If you conducted or watched a personal interview and the transcript or audio is not available for the reader, then there really isn’t any point to create a full reference. These types of sources are not recoverable and the reader would be unable to find the interview on their own. Instead, only create a citation in the text of the paper. Use the first initial, middle initial, and last name of the person being interviewed, along with “personal communication,” and the date of the interview.

Institution or organization name. (n.d.). Entry title. In Title of Website or reference . Retrieved Month Day, Year, from URL

Merriam-Webster. (n.d.). Doleful. In Merriam-Webster.com dictionary. Retrieved March 1, 2020, from https://www.merriam-webster.com/dictionary/doleful

Citing online encyclopedias & dictionaries – Known author

If there is a known author, cite the source this way:

Last name, F. M. (Date published). Entry title. In F. M. Last name (ed.), In Title of Website or reference . Retrieved Month Day, Year, from URL

Mann, M. E. & Selin, H. (n.d.). Global warming. In Encyclopaedia Britannica . Retrieved March 1, 2020, from https://www.britannica.com/science/global-warming

Citing Wikipedia

Cite a Wikipedia page just like a normal webpage, but use an archived version. Go to the “View history” tab at the top of a Wikipedia page to find these archived versions, their publishing date, and their URL.

Citing Media Sources in APA

Citing a song or music listened to online in apa.

Note: include a URL in the reference if that location is the only means of retrieval (like if they only post their music to SoundCloud or on their own specific website). If the song is available across multiple platforms, no URL is needed.

APA Structure for a modern song:

Artist’s Last Name, F. M. (Year published). Song’s title [Song].  On Title of album . Publisher(s).

Grande, A. (2019). 7 rings [Song]. On thank u, next . Republic Records.

Solution #3: How to ensure that an auto-generated citation in APA style is correct

• Ensure that the correct number of people are accredited by counting the names in the source and the website citation.
• Ensure that all names are spelled correctly.
• If 2-20 authors are used, ensure that an ampersand is used before the last name.
• If more than twenty authors are used, ensure that an ellipsis is used before the final author.
• Check to make sure that the date is correct and that the month or year do not need to be adjusted.
• Generally, works cited as a whole, such as books, are written in italics, while shorter works that are part of a bigger work, such as a chapter in a book or articles from a periodical (e.g., journal, magazine, newspaper, etc.), are usually in regular font.
• The title of webpages are italicized, while the title of the site they are on is in regular font.
• Social media post citations use the written post content (up to 20 words) as the title. This “title” should be italicized.
• If using a chapter, make sure that the editor is accredited.
• If using an article, make sure that the journal number is italicized and that the volume number is in parentheses.
• Make sure that your links are active and that they bring you to the correct location. You may need to rewrite the link.

Citation examples

This page lists the details you will need to include when writing citations for various types of source material. The examples given are in the 'Cite Them Right' version of the Harvard style.

For each example:

• Reference list  refers to the way it would be cited in your reference list or bibliography when using the 'Cite Them Right' Harvard style.
• In-text citation  refers to the way that a work would be cited either in the body of the text or in footnotes when using 'Cite Them Right' Harvard style.
• Referencing styles in use in the University Find out which style your Department uses. Please consult your course handbook for definitive guidance on which style to use.
• Styles of referencing Overview of different referencing styles in use at the University.

Note that, whatever the type of source, the title of the containing volume (i.e. the book, journal, collection etc) should always be marked out, usually by being put in italics but sometimes underlined. Whichever you use, be consistent and use the same formatting throughout your citations.

If the source you want to cite is not listed here consult the following book:

Alternatively ask your Academic Liaison Librarian or a Study Adviser for guidance:

• Contact your Academic Liaison Librarian
• Make an appointment with a Study Adviser

Elements to include:

• Authors or Editors
• Year of publication (in round brackets)
• Title (in italics)
• Edition (if applicable)
• Place published
• Series and volume number (if applicable)

Authored book:

Reference list: Ashbourn, J. (2014)  Biometrics in the new world: the cloud, mobile technology and pervasive identity . 2nd edn. London: Springer .

In-text citation:   (Ashbourn, 2014)

Edited book:

Reference list: Nasta, S. and Stein, M.U. (eds) (2020)  The Cambridge history of Black and Asian British writing . Cambridge: Cambridge University Press.

In-text citation:   (Nasta and Stein, 2020)

Where an e-book looks like a printed book (usually PDFs) with publication information and page numbers - cite it in the same way as a printed book (above). Where specific pagination details are not available use the information you have e.g. %, loc, chapter/page/paragraph. Also add the DOI or web address to the full reference.

Reference list: Prior, H. (2020) Away with the penguins . Available at: https://www.amazon.co.uk/Away-Penguins-Hazel-Prior-ebook (Accessed: 20 September 2021).

In-text citation: (Prior, 2020, 74%)

Reference list: Faulkner, W. (2000) Light in August. Available at: https://www.vlebooks.com/vleweb/product/openreader?id=UniReading&isbn=9781446485521 (Accessed: 10 September 2021).

In-text citation: (Faulkner, 2000, ch. 7, p. 105)

• Elements to include
• Print journals or print journals now online
• Online only journals
• Versions in repositories

The information you include in the reference will depend on whether the journal is published in print (but uploaded for electronic access), only published online, or is a version found in an institutional repository. You can usually tell the difference by looking for page numbers. If each article in the journal begins at page 1, or has no page number at all, it is likely to be an online-only journal. 

• Article title (in single quotation marks)
• Journal title (in italics, capitalise the first letter of each word except linking words)
• Volume number
• Issue number (if present, in round brackets)
• Page numbers or article reference number (Include the page numbers of the whole article when writing your full citation, not just the pages you have referred to)
• DOI or web link for online-only articles

See the examples in the other tabs in this box.

Examples for articles in print copies of journal articles or a print journal accessed online (e.g. on JSTOR)

Traditionally all articles were published in print format in issues which then formed part of a volume and this way of citing them (giving volume, issue and page numbers) has been retained even though most are now available online. There is no need to include the DOI or web address for articles with volume numbers and page numbers or an article reference number even if you accessed them online.

A single author:

Reference list:   Gulddal, J. (2020) 'That deep underground savage instinct: narratives of sacrifice and retribution in Agatha Christie's Appointment with Death',  Textual Practice,  34(11), pp. 1803-1821.

In-text citation: (Gulddal, 2020)

Two authors - include them both separated by 'and' or &:

Reference list:  Thomas, D. and Tian, L. (2021) 'Hits from the Bong: the impact of recreational marijuana dispensaries on property values',  Regional Science and Urban Economics,  87, article number 103655.

In-text citation: (Thomas and Tian, 2021)

Three authors - include them all, separate the first two with a comma and use 'and' or & before the third author:

Reference list:  Adeyeye, S.A.O., Ashaolu, T.J. and Idowu-Adebayo, F. (2022) 'Mycotoxins: food safety, consumer health and Africa's food security',  Polycyclic Aromatic Compounds , 42(8), pp. 5779–5795.

In-text citation: (Adeyeye, Ashaolu and Idowu-Adebayo, 2022)

Four or more authors - include them all in the full reference , but for the in-text citation just state the first author, followed by  et al .

Reference list: Moise, L., Gutiérrez, A.H., Khan, S., Tan, S., Ardito, M., Martin, W.D. & De Groot, A.S. (2020) 'New immunoinformatics tools for swine: designing epitope-driven vaccines, predicting vaccine efficacy, and making vaccines on demand',  Frontiers in Immunology,  11, article number 563362.

In-text citation:   (Moise  et al. , 2020)

Examples for online-only journals

If the journal is ONLY available online, you should include the DOI or the URL in the full reference. Online-only journal articles may not have page numbers or reference numbers, or pagination for each article will begin with '1'. The rules for in-text citations are the same as for print articles.

Article with a DOI:

Reference list:  Mair, A., Poirier, M. and Conway M.A. (2021) 'Age effects in autobiographical memory depend on the measure',  PLoS one,  16(10), article number e0259279. Available at: https://doi.org/10.1371/journal.pone.0259279

Article without a DOI:

Reference list: Farrell, L.G. (2013) 'Challenging assumptions about IT skills in higher education'. Journal of Learning Development in Higher Education , 6. Available at: http://www.aldinhe.ac.uk/ojs/index.php?journal=jldhe&page=article&op=view&path[]=173&path[]=138 (Accessed: 23 June 2021).

Examples for versions of articles found in repositories

Authors will often put versions of their articles into institutional repositories to comply with funding requirements to make the research Open Access. These may be pre-print versions (before peer review has taken place) or post-print versions, also known as author accepted manuscripts (the final version of the text, following peer review, to be published in the journal).

Pre-print example

Allen, R. J., Horowitz, L. W., Naik, V., Oshima, N., O'Connor, F., Turnock, S., Shim, S., Le Sager, P., Van Noije, T., Tsigaridis, K., Bauer, S. E., Sentman, L. T., John, J. G., Broderick, C., Deushi, M., Folberth, G., Fujimori, S. and Collins, B.  (2021) 'Significant climate benefits from near-term climate forcer mitigation in spite of aerosol reductions'. To be published in Environmental Research Letters  [Preprint]. Available at: http://centaur.reading.ac.uk/view/creators/90004988.html (Accessed: 24 June 2021).

For post-prints which are identical in content to the published version, you should cite the published version instead of citing the repository version.

• Chapter author(s)
• Chapter title in single quotation marks
• 'in' followed by book author(s)/editor(s)
• Book title (in italics)
• Publisher's name
• Chapter pagination

Include the page extent of the whole chapter when writing your full citation. Put just the pages you have referred to in the in-text citation.

Reference list: Singh, H., Khurana, L.K. and Singh, R. (2018) 'Pharmaceutical development', in Vohora, D. and Singh, G. (eds)  Pharmaceutical medicine and translational clinical research , London: Academic Press, pp.33-46.

In-text citation: (Singh, Khurana and Singh, 2018, p.35)

You can find many different types of information on the Internet. Check that the item you are referencing isn't a journal article, book chapter, or another type of publication which you should be citing in a different way.

Further guidance on referencing websites

Have a look at this Study Advice video tutorial (note that the format of the examples may not match the guidance given above):

• Referencing websites (video) Watch this brief video tutorial for more on the topic.
• Referencing websites (transcript) Read along while watching the video tutorial.

A secondary reference is used when you are referring to a source which you have not read yourself, but have seen quoted or read about in another source.  Where possible, you should always try to read the original of anything you wish to refer to ; otherwise you are relying on the author who cited the reference to have interpreted it correctly and not taken it out of context. Use the reference list at the end of the source you are reading to find details of the reference and search for it using the search boxes below.

Find books using the Enterprise catalogue

Just type in the first author's surname and a few words from the title.

Find journal articles using Summon

Just type in the first author's surname and first part of the article title.

If you can't get hold of the original source you'll need to do a secondary reference and you should make clear that you are not using the original source. Only include the source you have used in your list of references following the guidance for citing that type of publication. 

Different Schools/Departments might have different preferred ways of doing this, so do check any advice you are given or ask your course tutor if you are not sure. Otherwise, this is general guidance.

If the author quotes another source:

F rance (2003, quoted in Weingart et al ., 2018, p. 24) provides evidence that hospitals use internal reporting procedures to identify...

Table taken directly from another source

Tables should be sequentially numbered in your work with the title above the table - as in the following example in the Harvard referencing style. When referring to the table in your writing use the table number. 

A citation should be included at the end of the table title and a full citation added to your reference list for the source. 

Example of referring to a table in a sentence:

The macronutrient content of the diets used in the study is shown in Table 2. 

Mitchell, N.S. and Ard, J.D. (2021) 'Weight loss, lifestyle, and dietary factors in cardiovascular diseases in African Americans and Hispanics', in Ferdinand, K.C., Taylor, H.A. and Rodriguez, C.J. (eds)  Cardiovascular disease in racial and ethnic minority populations . Cham: Humana Press, pp. 167-182.

Table you have compiled yourself from multiple sources

If you are taking information from multiple sources and compiling your own table you still need to acknowledge those sources. 

Once again your table will need to be numbered in sequence with other tables in your work and have a title. For example:

Table 1: Turnover of Tesco PLC 2017-2021

You can then add a, b, c etc next to the statistics in the table (or the columns depending on how your data is arranged, see the example linked below) and then add a matching lettered list of citations for the sources at the bottom of the table:

Sources: a Tesco PLC (2017); b Tesco PLC (2018) etc

 Then in your reference list the end of your work, you would add the full reference for each source. For example:

Tesco PLC (2017)  Annual report and financial statement . Available at:  https://www.tescoplc.com/investors/reports-results-and-presentations/reports-archive/  (Accessed: 10 November 2022).

Tesco PLC (2018) Annual report and financial statement . Available at:  https://www.tescoplc.com/investors/reports-results-and-presentations/reports-archive/  (Accessed: 10 November 2022).

 See the following example where a & b has been added to the columns, as everything in that column has come from the same source:

• Example of citing multiple sources used in a table

The other option is to arrange it with the brief citations in the table. See Table 1 in the following example. The full references would go into your reference list at the end of the work in the same way as Method 1.

• How to cite sources in a table (Method 2) This example is in the APA referencing style but the same approach would work with Harvard.

It is strongly recommended that you use published sources such as books and journal articles in your assignments instead of materials posted by academics on Blackboard. Always check with the academic who has set the assignment whether you are allowed to include citations for their materials in your work.

Significance and implications of accurate and proper citations in clinical research studies

Citations are an essential component of clinical research studies. In health sciences most articles will refer to over 20 other peer-reviewed publications [ 1 ]. Citations are a core part of the entire research process. Citations fuel literature reviews [ 2 , 3 ] and they allow researchers to link their experiments to previous results and conclusions and establish credibility [ 2 , 4 , 5 ]. Citations can help authors contribute to the growing compilation of literature and prevent plagiarism [ 6 , 7 ]. However, prior studies have acknowledged a prevalence of improper citation [ [8] , [9] , [10] , [11] ]. Studies report citation inaccuracy rates of approximately 20–26% in biomedical literature [ 8 , 9 ]. Some studies have also reported citation inaccuracies within field-specific journals such as pediatric orthopaedics [ 8 ], neurosurgery [ 12 ], spine surgery [ 13 ], and foot and ankle surgery [ 14 ]. This trend is especially alarming as citation inaccuracies can diminish research validity [ 15 ]. Recognizing the causes or instances of inaccurate citations can prevent further improper citation [ 16 ].

1. What are the root causes of citation inaccuracies?

Citation misuse can originate in literature reviews, as authors can find and choose references in arbitrary fashions. This can stem from keyword choice; many authors use broad keywords to garner a large audience, but this can hurt the number of references they receive [ 17 ]. Language can also be a barrier: one study found over 30% of systematic reviews excluded studies not published in English, which dramatically decreases the scope of literature reviews [ 18 ]. Researchers may also be biased towards articles with many citations. This can be described as the ‘Matthew effect:’ the more a paper is referenced, the more it will continue to be referenced [ 19 , 20 ]. This is concerning as citation rate of articles is not necessarily an indicator of quality or significance [ 21 ]. While papers with many citations continue to receive attention, less cited articles may be neglected, potentially hindering research advancements.

Literature reviews may also be influenced by other arbitrary factors. For example, an author's social media presence showed a positive correlation with the rate at which they were cited [ 22 , 23 ]. Another consideration for citation rate is the primacy effect, which describes how citations listed earlier in a study are used more frequently than those that appear toward the end of a study [ 24 ]. The reputation of the author(s), organization(s), journal, or country represented by a paper may also play a role in the number of times it is cited [ 25 ]. Some authors or groups of authors may receive an increased number of citations based on their production level or experience in the field of study [ 25 ]. Additionally, luck and last name may inevitably affect the rate at which someone is repeatedly cited.

2. What are examples of citation inaccuracies?

Selective citation, whether purposeful or subconscious, is an endemic problem [ 11 , 26 , 27 ]. Studies showing positive results are cited more often than those with neutral or negative results, a phenomenon known as citation bias [ 26 ]. This gives readers a biased view and overrepresents positive findings [ 26 ]. Other common forms of improper citation usage include: secondary citation, incorrect/opposite conclusion, back door invention, fact not found, and inaccurate population. Secondary citation, or “amplification,” is the act of citing a fact in a paper that was itself supported by a citation instead of going to the original article [ 16 ]. Amplification leads to the expansion of a belief without additional primary data [ 10 ]. Incorrect/opposite conclusion occurs when inaccurate or missing information is cited. Specifically, an author may cite an article presenting the opposite conclusion referred to in the study [ 16 ]. This error is especially detrimental as studies make claims contradicting the citation, yet this contradiction may be further perpetuated in future studies via amplification. “Back door invention” is the error of citing abstracts while leading the reader to believe it is a peer-reviewed article [ 10 ]. Fact not found consists of a claim that a cited article has stated a fact or statistic, when in reality did not mention it at all and is therefore unsupported [ 16 ]. Lastly, inaccurate population involves the referencing of a study which may have found the results reported, but the results obtained in the cited article may not be generalizable to the population in the new study [ 16 ]. Research has also shown that citation of retracted studies occurs in many fields and these studies are often cited positively [ [28] , [29] , [30] , [31] ]. One study showed that even after 5 years, retracted studies by an author were still being cited, with only 25% of citations acknowledging it had been retracted [ 31 ].

3. What can be done to prevent or correct citation inaccuracies?

Solutions to many of these problems have been shared [ [15] , [16] , [17] , 22 , 23 ]. Authors can help others find their research by using targeted rather than generic keywords [ 17 ]. Similarly, a social media presence by journals and authors may be warranted to improve discoverability [ 22 , 23 ]. While not feasible for all literature reviews, machine learning has been used in finding relevant references for systematic reviews [ 32 ]. In short, machine learning is a form of artificial intelligence that allows systems to create algorithms based on data received. Future improvements in machine learning may allow for widespread use in finding and citing references in a way that is both efficient and accurate. One solution that has been proposed is the development of a tool named MyCites [ 33 ]. This tool would allow for the ability to mark citations as inaccurate and have these notations travel with the digital document so that future readers are aware of the accuracy of any contested citations [ 33 ]. These capabilities may help to stifle early citation inaccuracies and prevent the amplification of inaccurate citations.

Given the prevalence of citation inaccuracies, it is imperative those involved in the peer review process review submissions with an eye toward citation accuracy. At the start, authors must thoroughly recheck their citations and verify the relevance and validity of each reference. [ 34 ] One survey showed that only 4% of published scientists regularly check citations in articles they read [ 3 ]. Some authors have suggested that a simple checklist would avoid most errors [ 16 ]. It has also been suggested that editors develop training courses for authors outlining the acceptable citation styles pertinent to a particular journal [ 34 ]. Reviewers are in the unique role of making sure that new submissions are, evidence-based, in publishable condition, and add to the current body of knowledge. Such responsibility also includes evaluating the references of these submissions and suggesting the alteration, removal, or addition of references which would ensure citation accuracy [ 34 ]. The peer review process can help correct citation mistakes, especially through increased spot checks by editors/reviewers [ 9 ]. Lastly, the publisher's role in citation accuracy has started to include the use of software to process, link, and check the quality of references. [ 35 ] The increased utilization of new technology to verify citation accuracy will be of great benefit to both researchers and readers.

We also seek to share common guidelines for proper citation. First, ensure the citation provides correct publication details, including name, article title, and journal [ 15 ]. Second, the citation must substantiate the claim [ 15 ]. Next, authors should use unbiased sources that provide reliable data [ 15 ]. Articles from prestigious journals should not be assumed as reliable; analysis of the article itself is critical [ 15 ]. Additionally, be mindful of reconciling evidence. Authors should present the information in an objective manner [ 15 ]. In research it is crucial for “evidence to guide conclusions.” [ 36 ] Citations are an important part of the scientific process. They allow researchers to support and share findings, helping to further innovation. However, citations can be misused, slowing progress in clinical research and circulating unsupported beliefs. Many problems with citations can be fixed with increased attention to detail by authors and editors, ultimately strengthening credibility of the literature.

Purpose of Research Paper Citation

The purpose of citing sources in a research paper is to give credit to the original authors and acknowledge their contribution to your work. By citing sources, you are also demonstrating the validity and reliability of your research by showing that you have consulted credible and authoritative sources. Citations help readers to locate the original sources that you have referenced and to verify the accuracy and credibility of your research. Additionally, citing sources is important for avoiding plagiarism, which is the act of presenting someone else’s work as your own. Proper citation also shows that you have conducted a thorough literature review and have used the existing research to inform your own work. Overall, citing sources is an essential aspect of academic writing and is necessary for building credibility, demonstrating research skills, and avoiding plagiarism.

Advantages of Research Paper Citation

There are several advantages of research paper citation, including:

• Giving credit: By citing the works of other researchers in your field, you are acknowledging their contribution and giving credit where it is due.
• Strengthening your argument: Citing relevant and reliable sources in your research paper can strengthen your argument and increase its credibility. It shows that you have done your due diligence and considered various perspectives before drawing your conclusions.
• Demonstrating familiarity with the literature : By citing various sources, you are demonstrating your familiarity with the existing literature in your field. This is important as it shows that you are well-informed about the topic and have done a thorough review of the available research.
• Providing a roadmap for further research: By citing relevant sources, you are providing a roadmap for further research on the topic. This can be helpful for future researchers who are interested in exploring the same or related issues.
• Building your own reputation: By citing the works of established researchers in your field, you can build your own reputation as a knowledgeable and informed scholar. This can be particularly helpful if you are early in your career and looking to establish yourself as an expert in your field.

Basic Format for Books

Edited book, no author, edited book with an author or authors, a translation.

Note : When you cite a republished work, like the one above, in your text, it should appear with both dates: Plato (385-378/1989)

Edition Other Than the First

Article or chapter in an edited book.

Note : When you list the pages of the chapter or essay in parentheses after the book title, use "pp." before the numbers: (pp. 1-21). This abbreviation, however, does not appear before the page numbers in periodical references, except for newspapers. List any edition number in the same set of parentheses as the page numbers, separated by a comma: (2nd ed., pp. 66-72).

Multivolume Work

Articles in periodicals.

APA style dictates that authors are named with their last name followed by their initials; publication year goes between parentheses, followed by a period. The title of the article is in sentence-case, meaning only the first word and proper nouns in the title are capitalized. The periodical title is run in title case, and is followed by the volume number which, with the title, is also italicized. If a DOI has been assigned to the article that you are using, you should include this after the page numbers for the article. If no DOI has been assigned and you are accessing the periodical online, use the URL of the website from which you are retrieving the periodical.

Article in Print Journal

Note: APA 7 advises writers to include a DOI (if available), even when using the print source. The example above assumes no DOI is available.

Article in Electronic Journal

Note :  This content also appears on Reference List: Online Media .

As noted above, when citing an article in an electronic journal, include a DOI if one is associated with the article.

DOIs may not always be available. In these cases, use a URL. Many academic journals provide stable URLs that function similarly to DOIs. These are preferable to ordinary URLs copied and pasted from the browser's address bar.

Article in a Magazine

Article in a newspaper.

As the series: "Modern treatment of Autoinflammatory diseases" concludes, it is still far from exhausting its subject, in spite of presenting some of its very intriguing aspects.In the series, we've paid closer attention to Still's disease, an example of autoinflammatory phenomena among rheumatic diseases [1] and -in the form of adult onset Still's disease (AOSD) -a possible mask of a developing malignancy, especially of lymphoproliferative diseases [2]. Its potential therapies focus on the activity of proinflammatory cytokines, such as interleukin-1 (IL-1) and IL-6 [3].A retrospective study using data from the "Autoinflammatory Disease Alliance" (AIDA) registry entitled: " Efficacy of canakinumab in patients with Still's disease across different lines of biologic therapy: real-life data from the International AIDA Network Registry for Still's Disease" presented the usefulness of anti-IL-1 treatment regardless of which line of treatment this biologic is used in. Although it's not uncommon (5-12%), lung involvement is often overlooked in AOSD.Importantly, systemic juvenile idiopathic arthritis-lung disease (sJIA-LD) should be distinguished from the systemic form of JIA [4]. Interestingly, an anaphylactoid reaction to drugs, including anti-IL-1 and anti-IL-6 monoclonal antibodies, is reported as a risk factor for the development of sJIA-LD 5, 6 [7,8] .The lung involvement in AOSD, associated with higher mortality [5], is indicated by BAL-F results, often with neutrophilia and by a picture of inflammatory infiltrates and consolidations in HRCT [7,8] -although infection needs to be excluded. The authors of "Rare, rarer, lung involvement in adult-onset Still's disease: A mini-review" emphasize the importance of HRCT imaging in this condition and a significance of the increase in pro-inflammatory cytokines and acute phase proteins (IL1, IL-6, ferritin), which -although not specific to the lung involvement itself -correlate with its severity and a risk of developing acute respiratory distress syndrome (ARDS) and hemophagocytic lymphohistiocytosis (HLH)/macrophage activation syndrome (MAS), which may increase mortality. In treatment, GCs and methotrexate, calcineurin inhibitors, and in the case of recurrent disease, inhibition of IL-6 and IL-1 are used.Infections, triggering factors of autoimmune and autoinflammatory diseases, are associated with a macrophage activation [6,9] resulting in the presence of antibodies blocking INF-γ, STAT-1 phosphorylation and chemokine activity. These phenomena influence susceptibility to opportunistic infections in AOSD, as demonstrated in the study "High-titer anti-interferon-γ neutralizing autoantibodies linked to opportunistic infections in patients with adultonset Still's disease".The treatment of autoinflammatory diseases has seen an increasing role of IL-1 inhibition.Canakinumab, playing currently the most prominent role in this regard, was the subject of the article titled: "The safety and efficacy of canakinumab treatment for undifferentiated autoinflammatory diseases: the data of retrospective cohort two-centered study", which focused on the analysis of young patients with undifferentiated autoinflammatory disease (uAID), showing that the majority (84%) of uAID patients in the treatment group presented remission.Interestingly, the earlier CANTOS study conducted in patients after acute coronary syndromes and strokes with increased ultra-sensitive CRP, showed up to 15% reduction in deaths with the use of canakinumab. However, the risk of complications caused by infections was slightly higher (although overall low) in the canakinumab group compared to placebo, while in the longer term, there was a reduction in the incidence of lung cancer and mortality in the canakinumab group compared to placebo [10].An another example of the effectiveness of inhibiting the pro-inflammatory activity of IL-1 was presented in the study "Effectiveness and safety of anakinra in gouty arthritis: a case series and review of the literature", based on data from the literature regarding 551 patients treated both during flares and chronically, supporting the use of such treatment in refractory gout.In cases of rare diseases, including mono-and polygenic autoinflammatory ones, studies of individual cases (often later taken into account for meta-analyses) play a vital role, especially when transcriptomic analysis is taken into account To sum up, progress in treating autoinflammatory and autoimmune diseases is related to the constantly expanding knowledge about the pathogenesis of these diseases. The treatment targeted at specific cytokines, such as e.g. IL-1, and other elements of the immune system involved in the activation of inflammation, is currently therapeutic standards.
