Citation Styles

What is a Citation?

A citation is positioned within the body of your paper, right after you finish referencing or quoting another author's work. This is known as an inline or in-text citation. At the end of your paper, you will also provide a complete reference. A reference must provide enough information to both identify and locate the original source of the information.

A reference usually includes:

  • Name(s) of author(s)
  • Title of source (article or chapter title and journal or book title)
  • Publication date (if known)
  • Page number(s)
  • Volume and edition/issue numbers (for books and articles)
  • If the content is likely to change over time, include the date you originally accessed the content.

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)

Getting Started: How to use this guide

This LibGuide was designed to provide you with assistance in citing your sources when writing an academic paper.

There are different styles which format the information differently. In each tab, you will find descriptions of each citation style featured in this guide along with links to online resources for citing and a few examples.

What is a citation and citation style?

A citation is a way of giving credit to individuals for their creative and intellectual works that you utilized to support your research. It can also be used to locate particular sources and combat plagiarism. Typically, a citation can include the author's name, date, location of the publishing company, journal title, or DOI (Digital Object Identifier).

A citation style dictates the information necessary for a citation and how the information is ordered, as well as punctuation and other formatting.

How to do I choose a citation style?

There are many different ways of citing resources from your research. The citation style sometimes depends on the academic discipline involved. For example:

  • APA (American Psychological Association) is used by Education, Psychology, and Sciences
  • MLA (Modern Language Association) style is used by the Humanities
  • Chicago/Turabian style is generally used by Business, History, and the Fine Arts

*You will need to consult with your professor to determine what is required in your specific course.

APA (American Psychological Association) style is most frequently used within the social sciences, in order to cite various sources. This APA Citation Guide provides the general format for in-text citations and the reference page. For more information, please consult the Publication Manual of the American Psychological Association , 7th ed.

In APA style, two citations are used to cite a source:

  • A short citation used in the text (called the in-text citation ).
  • A full citation (called the reference ) in the reference list at the end of a paper.

The in-text citation is a short citation that is placed next to the text being cited. The in-text citation lets the reader know that the information came from the cited source. The reference list entry provides complete details of a source and is shown at the end of a document.

In order to properly cite a source in APA style, you must have both citation types in your paper. Every in-text citation has a reference list entry. Every reference list entry has at least one (maybe more) corresponding in-text citation.

In-text citations

The basic elements needed for an in-text citation are the author’s surname and the publication year . Sometimes, page numbers are also included, especially when quotes are mentioned in the text. In-text citations are mentioned in the text in two ways: as a narrative citation or a parenthetical citation.

Narrative citations are incorporated into the text and act as a part of the sentence. Usually, narrative citations use the author’s name in the text and the publication year is enclosed in parenthesis after the name. An example of a narrative citation for one author is given below:

Barbarin (2013) examined socioemotional learning in African boys.

Parenthetical

Parenthetical citations add the author’s name and the publication year at the end of the sentence in parenthesis. An example of a parenthetical citation is given below:

Inhibition and working memory in young children were studied extensively (Aase, 2014).

When are page numbers are included?

Page numbers are referred to within in-text citations when quotes are used. Examples of both narrative citations and parenthetical citations are given below.

Ahmed (2004, p. 44)

Ahmed (2004, pp. 53–56)

Parenthetical:

(Ahmed, 2004, p. 44)

(Ahmed, 2004, pp. 53–56)

Examples of in-text citations

Here are a few examples of in-text citations for a different number of authors:

Use the surname of the author in in-text citations. Use a comma before the publication year in parenthetical citations.

Narrative: 

Bucher (2018)

Parenthetical: 

(Bucher, 2018)

Two authors

Separate the author surnames with an “and” in narrative citations. Use an ampersand symbol (&) in parenthetical citations.

Popescu and Pennacchiotti (2010)

(Popescu & Pennacchiotti, 2010)

Three or more authors

Use the first author surname name followed by et al.

van Dijck et al. (2018)

(van Dijck et al., 2018)

Group author

Treat the group author similar to how you would treat author names.

Auger Collaboration (2003)

(Auger Collaboration, 2018)

If there is no author for the source, use the source title in place of the author’s name. In general, sources with no author appear as parenthetical citations.

When you add such in-text citations, you will either italicize the text or place it in quotations. If the source title is italicized in the reference list entry, italicize the title in the in-text citation. If the title is not italicized, place it in quotation marks.

Parenthetical, book:

( Nothing here , 1997)

Parenthetical, journal article:

(“Examination of parrotfish impact on coral reefs,” 2018)

Reference list entries

Reference list entries are also called full citations. There are four main details that most reference list entries have:

  • The author field.
  • The publication year.
  • The title of the work ( italicized or in “quotation marks”).
  • The source from where the reference can be obtained (e.g., URL, DOI, etc.).

Depending on the source type, you will also need additional details like volume number, publication title, contributors, medium, etc.

Examples of reference list entries

Below are a few examples of different types of reference entries along with their templates. The examples given are for one author. Note that “F” and “M” in the templates denote the first and the middle initials of an author’s name.

The title of the book is set in italics and sentence case.

Author Surname, F. M. (Publication Year). Title of the book . Publisher.

Ahmed, S. (2014). The cultural politics of emotion . Edinburgh University Press.

Journal article

The title of the article is in sentence case. The first word of a subtitle is capitalized. The journal title and the volume number are set in italics. If an article has a DOI it should always be included. Use “https://doi.org/” before the DOI. If there is no DOI for an online journal, include the URL instead. Do not use a period after the DOI or URL.

Author Surname, F. M. (Publication Year). Article title: Subtitle. Journal Title, Volume (issue), page range. URL or DOI

Newspaper or magazine article

Newspaper and magazine articles take the same style. The title of the article is in plain text and sentence case; the title of the newspaper or the magazine is set in italics. Follow the format given in the template and example for setting the date, month, and year.

Surname, F. M. (Date of publication). Title of the article. Title of the Newspaper or Magazine . URL

YouTube video

The video title is set in sentence case and italicized. The first word after a colon is capitalized. The word “Video” is enclosed in brackets after the video title. This is followed followed by the word “YouTube.” Finally, the link is given. Note that a period is not given after the URL.

Uploader’s name, F. (Year, Month Day Published). Video title [Video]. YouTube. URL

Ananta, P. (2021, February 21). APJ Abdul Kalam inspirational quotes [Video]. YouTube. https://www.youtube.com/watch?v=pjfL51RFL2k

Reference entries for different number of authors

The number of authors in the source decides how the author name(s) will be set in the references list. Here, you will see many journal references with different numbers of authors.

List the author name followed by the publication year.

Author Surname, F. M. (Publication Year). Article title: Subtitle. Journal Title, Volume (issue), page range.

Spitka, T. (2017). Mediating among mediators: Building a consensus in multilateral interventions. International Negotiation, 23 , 1–30.

Separate the author names by an ampersand. Use a comma between the first author’s initial and the ampersand symbol.

Author Surname, F. M., & Author Surname, F. (Publication Year). Article title: Subtitle. Journal Title, Volume (issue), page range. DOI or URL

Bernstein, B., & Solomon, J. (1999). Pedagogy, identity and the construction of a theory of symbolic control: Basil Bernstein questioned by Joseph Solomon. British Journal of Sociology of Education, 20 (2), 265–279. https://doi:10.1080/01425699995443

When you add two organizations in the author field, do not use a comma before the ampersand.

Organization 1 & Organization 2. (Publication Year). Article title: Subtitle. Journal Title, Volume (issue), page range. DOI or URL

As per Section 8.17 from the Publication Manual of the American Psychological Association , for any work that has three or more authors, the name of the first author and “et al.” should be used as in-text citation. The Latin phrase “et al” means “and others” and is used to reduce the citation length.

Example In-Text Citation Entry:

No stretch of reason can categorize cultural appropriation as imaginary (Rahim et al., 2020).

Sometimes, the same set of initial authors and the same publication year appear in a paper. In such rare circumstances, as per Section 8.18 of the APA manual, write out as many names as needed to differentiate between these similar references.

Example In-Text Citation Entries:

Miller, John, Reighstag et al. (2018)

Miller, John, Amudsen, et al. (2018)

As per Section 8.21 and Table 8.1 of the APA Publication Manual , a citation for a group author may be abbreviated in in-text citations. It is not compulsory to do so; however, if the group author is well known or if it appears at least thrice in the paper, then the name of the group may be abbreviated.

Parenthetical in-text citation template and example:

(Full Name of the Group [Abbreviation], year)

(National Institute of Mental Health [NIMH], 2018)

Whether it is a narrative or parenthetical in-text citation, the full name of the group should be mentioned in the first instance, along with the abbreviation.

Narrative in-text citation examples:

The American Psychological Association (APA, 2017) argues that
 (first instance)

As per the APA (2017), it is standard practice that

  • 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).

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.

  • 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.

  • 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.

  • 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.

Harvard Style

The Harvard referencing system is known as the Author-Date style . It emphasizes the name of the creator of a piece of information and the date of publication, with the list of references in alphabetical order at the end of your paper.

Unlike other citation styles, there is no single, definitive version of Harvard Style. Therefore, you may see a variation in features such as punctuation, capitalization, abbreviations, and the use of italics. 

Always check with your instructor and follow the rules he or she gives you.

  • Harvard Style Guidelines Your class handout
  • Harvard Referencing Quick Guide From Staffordshire University

Harvard Style will affect your paper in two places:

  • In-text citations in the body of your paper, and
  • The reference list at the end of your paper
  • All in-text citations should be listed in the reference list at the end of your paper.
  • Reference list entries need to contain all the information that someone reading your paper would need in order to find your source.
  • Reference lists in Harvard Style are arranged alphabetically by first author.
  • Begin your Reference list on a new page after your text and number it consecutively.

In-Text Citations: The Basics

OWL logo

Welcome to the Purdue OWL

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

Copyright ©1995-2018 by The Writing Lab & The OWL at Purdue and Purdue University. All rights reserved. This material may not be published, reproduced, broadcast, rewritten, or redistributed without permission. Use of this site constitutes acceptance of our terms and conditions of fair use.

Note:  This page reflects the latest version of the APA Publication Manual (i.e., APA 7), which released in October 2019. The equivalent resource for the older APA 6 style  can be found here .

Reference citations in text are covered on pages 261-268 of the Publication Manual. What follows are some general guidelines for referring to the works of others in your essay.

Note:  On pages 117-118, the Publication Manual suggests that authors of research papers should use the past tense or present perfect tense for signal phrases that occur in the literature review and procedure descriptions (for example, Jones (1998)  found  or Jones (1998)  has found ...). Contexts other than traditionally-structured research writing may permit the simple present tense (for example, Jones (1998)  finds ).

APA Citation Basics

When using APA format, follow the author-date method of in-text citation. This means that the author's last name and the year of publication for the source should appear in the text, like, for example, (Jones, 1998). One complete reference for each source should appear in the reference list at the end of the paper.

If you are referring to an idea from another work but  NOT  directly quoting the material, or making reference to an entire book, article or other work, you only have to make reference to the author and year of publication and not the page number in your in-text reference.

On the other hand, if you are directly quoting or borrowing from another work, you should include the page number at the end of the parenthetical citation. Use the abbreviation “p.” (for one page) or “pp.” (for multiple pages) before listing the page number(s). Use an en dash for page ranges. For example, you might write (Jones, 1998, p. 199) or (Jones, 1998, pp. 199–201). This information is reiterated below.

Regardless of how they are referenced, all sources that are cited in the text must appear in the reference list at the end of the paper.

In-text citation capitalization, quotes, and italics/underlining

  • Always capitalize proper nouns, including author names and initials: D. Jones.
  • If you refer to the title of a source within your paper, capitalize all words that are four letters long or greater within the title of a source:  Permanence and Change . Exceptions apply to short words that are verbs, nouns, pronouns, adjectives, and adverbs:  Writing New Media ,  There Is Nothing Left to Lose .

( Note:  in your References list, only the first word of a title will be capitalized:  Writing new media .)

  • When capitalizing titles, capitalize both words in a hyphenated compound word:  Natural-Born Cyborgs .
  • Capitalize the first word after a dash or colon: "Defining Film Rhetoric: The Case of Hitchcock's  Vertigo ."
  • If the title of the work is italicized in your reference list, italicize it and use title case capitalization in the text:  The Closing of the American Mind ;  The Wizard of Oz ;  Friends .
  • If the title of the work is not italicized in your reference list, use double quotation marks and title case capitalization (even though the reference list uses sentence case): "Multimedia Narration: Constructing Possible Worlds;" "The One Where Chandler Can't Cry."

Short quotations

If you are directly quoting from a work, you will need to include the author, year of publication, and page number for the reference (preceded by "p." for a single page and “pp.” for a span of multiple pages, with the page numbers separated by an en dash).

You can introduce the quotation with a signal phrase that includes the author's last name followed by the date of publication in parentheses.

If you do not include the author’s name in the text of the sentence, place the author's last name, the year of publication, and the page number in parentheses after the quotation.

Long quotations

Place direct quotations that are 40 words or longer in a free-standing block of typewritten lines and omit quotation marks. Start the quotation on a new line, indented 1/2 inch from the left margin, i.e., in the same place you would begin a new paragraph. Type the entire quotation on the new margin, and indent the first line of any subsequent paragraph within the quotation 1/2 inch from the new margin. Maintain double-spacing throughout, but do not add an extra blank line before or after it. The parenthetical citation should come after the closing punctuation mark.

Because block quotation formatting is difficult for us to replicate in the OWL's content management system, we have simply provided a screenshot of a generic example below.

This image shows how to format a long quotation in an APA seventh edition paper.

Formatting example for block quotations in APA 7 style.

Quotations from sources without pages

Direct quotations from sources that do not contain pages should not reference a page number. Instead, you may reference another logical identifying element: a paragraph, a chapter number, a section number, a table number, or something else. Older works (like religious texts) can also incorporate special location identifiers like verse numbers. In short: pick a substitute for page numbers that makes sense for your source.

Summary or paraphrase

If you are paraphrasing an idea from another work, you only have to make reference to the author and year of publication in your in-text reference and may omit the page numbers. APA guidelines, however, do encourage including a page range for a summary or paraphrase when it will help the reader find the information in a longer work. 

Chicago-Style Citation Quick Guide

Chicago-style source citations come in two varieties: (1) notes and bibliography and (2) author-date. If you already know which system to use, follow one of the links above to see sample citations for a variety of common sources. If you are unsure about which system to use, or how the two systems are related, read on.

Notes and Bibliography or Author-Date?

In the notes and bibliography system, sources are cited in numbered footnotes or endnotes. Each note corresponds to a raised (superscript) number in the text. Sources are also usually listed in a separate bibliography. The notes and bibliography system, Chicago’s oldest and most flexible, can accommodate a wide variety of sources, including unusual ones that don’t fit neatly into the author-date system. For this reason, it is preferred by many working in the humanities, including literature, history, and the arts.

In the author-date system, sources are briefly cited in the text, usually in parentheses, by author’s last name and year of publication. Each in-text citation matches up with an entry in a reference list, where full bibliographic information is provided. Because it credits researchers by name directly in the text while at the same time emphasizing the date of each source, the author-date system is preferred by many in the sciences and social sciences.

Aside from the use of numbered notes versus parenthetical references in the text, the two systems share the same style for authors’ names, titles of works, and other cited components. Follow the links at the top of this page to see examples of some of the more common source types cited in both systems.

Most authors choose the system used by others in their field or required by their publisher. Students should check with their instructor before deciding which system to use.

For a more comprehensive overview of Chicago’s two systems of source citation, see chapter 13 of The Chicago Manual of Style . For many more examples organized by type of source, consult chapter 14 .

American Psychological Association

In-Text Citations

In scholarly writing, it is essential to acknowledge how others contributed to your work. By following the principles of proper citation, writers ensure that readers understand their contribution in the context of the existing literature—how they are building on, critically examining, or otherwise engaging the work that has come before.

APA Style provides guidelines to help writers determine the appropriate level of citation and how to avoid plagiarism and self-plagiarism.

We also provide specific guidance for in-text citation, including formats for interviews, classroom and intranet sources, and personal communications; in-text citations in general; and paraphrases and direct quotations.

Citing Sources: Which citation style should I use?

The citation style you choose will largely be dictated by the discipline in which you're writing. For many assignments your instructor will suggest or require a certain style. If you're not sure which one to use, it's always best to check with your instructor or, if you are submitting a manuscript, the publisher to see if they require a certain style. In many cases, you may not be required to use any particular style as long as you pick one and use it consistently. If you have some flexibility, use the guide below to help you decide.

Being responsible while researching

When you’re writing a research paper or creating a research project, you will probably use another individual’s work to help develop your own assignment. A good researcher or scholar uses another individual’s work in a responsible way. This involves indicating that the work of other individuals is included in your project (i.e., citing), which is one way to prevent plagiarism.

Plagiarism? What is it?

The word plagiarism is derived from the Latin word, plagiare , which means “to kidnap.” The term has evolved over the years to now mean the act of taking another individual’s work and using it as your own, without acknowledging the original author (American Psychological Association, 2020 p. 21). Plagiarism can be illegal and there can be serious ramifications for plagiarizing someone else’s work. Thankfully, plagiarism can be prevented. One way it can be prevented is by including citations and references in your research project. Want to make them quickly and easily? Try the Citation Machine citation generator, which is found on our homepage.

All about citations & references

Citations and references should be included anytime you use another individual’s work in your own assignment. When including a quote, paraphrased information, images, or any other piece of information from another’s work, you need to show where you found it by including a citation and a reference. This guide explains how to make them.

APA style citations are added in the body of a research paper or project and references are added to the last page.

Citations , which are called in-text citations, are included when you’re adding information from another individual’s work into your own project. When you add text word-for-word from another source into your project, or take information from another source and place it in your own words and writing style (known as paraphrasing), you create an in-text citation. These citations are short in length and are placed in the main part of your project, directly after the borrowed information.

References are found at the end of your research project, usually on the last page. Included on this reference list page is the full information for any in-text citations found in the body of the project. These references are listed in alphabetical order by the author's last name.

An APA in-text citation includes only three items: the last name(s) of the author(s), the year the source was published, and sometimes the page or location of the information. References include more information such as the name of the author(s), the year the source was published, the full title of the source, and the URL or page range.

Two example in-text citations.

Why is it important to include citations & references

Including APA citations and references in your research projects is a very important component of the research process. When you include citations, you’re being a responsible researcher. You’re showing readers that you were able to find valuable, high-quality information from other sources, place them into your project where appropriate, all while acknowledging the original authors and their work.

Common ways students and scholars accidentally plagiarize

Believe it or not, there are instances when you could attempt to include in-text and full references in the appropriate places, but still accidentally plagiarize. Here are some common mistakes to be aware of:

Mistake #1 - Misquoting sources: If you plan to use a direct quote, make sure you copy it exactly as is. Sure, you can use part of the full quote or sentence, but if you decide to put quotation marks around any words, those words should match exactly what was found in the original source. Here’s a line from The Little Prince , by Antoine de Saint-ExupĂ©ry:

“Grown-ups never understand anything by themselves, and it is tiresome for children to be always and forever explaining things to them.”

Here’s an acceptable option:

“Grown-ups never understand anything by themselves,” stated de Saint-ExupĂ©ry (1943, p. 3).

Here’s a misquote:

“Grown-ups barely ever understand anything by themselves,” stated de Saint-ExupĂ©ry (1943, p. 3).

Notice the slight change in the words. The incorrect phrasing is an instance of accidental plagiarism.

Mistake #2 - Problems with paraphrasing: When we paraphrase, we restate information using our own words and writing style. It’s not acceptable to substitute words from the original source with synonyms.

Let’s use the same sentence from The Little Prince .

A correct paraphrase could be:

de Saint-ExupĂ©ry (1943) shares various ways adults frustrate children. One of the biggest being that kids have to explain everything. It’s too bad adults are unable to comprehend anything on their own (p. 3).

An incorrect paraphrase would be:

de Saint-Exupéry (1943) shares that adults never understand anything by themselves, and it is exhausting for kids to be always and forever clarifying things to them (p.3).

Notice how close the incorrect paraphrase is from the original. This is an instance of accidental plagiarism.

Make sure you quote and paraphrase properly in order to prevent accidental plagiarism.

If you’re having a difficult time paraphrasing properly, it is acceptable to paraphrase part of the text AND use a direct quote. Here’s an example:

de Saint-Exupery (1943) shares various ways adults frustrate children. One of the biggest being that kids have to explain everything, and “it is tiresome for children to be always and forever explaining things to them” (p. 3).

Information About APA

Who created it.

The American Psychological Association is an organization created for individuals in the psychology field. With close to 121,000 members, they provide educational opportunities, funding, guidance, and research information for everything psychology-related. They also have numerous high-quality databases, peer-reviewed journals, and books that revolve around mental health.

The American Psychological Association is also credited with creating their own specific citation and reference style. Today, this format is used by individuals not only in the psychology field, but many other subject areas as well. Education, economics, business, and social sciences also use APA style quite frequently. Click here for more information . This guide covers general information about the style, but is not affiliated with the American Psychological Association.

Why was this style created?

This format was first developed in 1929 to form a standardized way for researchers in science fields to document their sources. Prior to the inception of these standards and guidelines, individuals were recognizing the work of other authors by including bits and pieces of information in random order. There wasn’t a set way to format citations and references. You can probably imagine how difficult it was to understand the sources that were used for research projects!

Having a standard format for citing sources allows readers to glance at a citation or APA reference and easily locate the title, author, year published, and other critical pieces of information needed to understand a source.

The evolution of this style

The guide below is based on APA style 7th edition, which was released in 2020. In previous versions of APA format, researchers and scholars were required to include the publisher location for books and the date that an electronic resource was accessed. Both are no longer required to be included.

Details on the differences between the 6th and 7th editions is addressed later in this guide.

Citations & References

The appearance of citations & references.

The format for references varies, but most use this general format:

%%Author’s Last name, First initial. (Date published). Title . URL

Researchers and scholars must look up the proper format for the source that they’re attempting to cite. Books have a certain format, websites have a different format, periodicals have a different format, and so on. Scroll down to find the proper format for the source you’re citing or referencing.

If you would like help citing your sources, CitationMachine.com has a citation generator that will help make the APA citation process much easier for you. To start, simply click on the source type you're citing:

  • Journal articles

In-text citations

An APA in-text citation is included in research projects in three instances: When using a direct quote, paraphrasing information, or simply referring to a piece of information from another source.

Quite often, researchers and scholars use a small amount of text, word for word, from another source and include it in their own research projects. This is done for many reasons. Sometimes, another author’s words are so eloquently written that there isn’t a better way to rephrase it yourself. Other times, the author’s words can help prove a point or establish an understanding for something in your research project. When using another author’s exact words in your research project, include an APA in-text citation directly following it.

In addition to using the exact words from another source and placing them into your project, these citations are also added anytime you paraphrase information. Paraphrasing is when you take information from another source and rephrase it, in your own words.

When simply referring to another piece of information from another source, also include a citation directly following it.

Citations in the text are found near a direct quote, paraphrased information, or next to a mention of another source. To see examples of some narrative/ parenthetical citations in action, look at the image above, under “All About Citations & References.”

Note: *Only include the page or paragraph number when using a direct quote or paraphrase. Page numbers have a p. before the number, pp. before the page range, and para. before the paragraph number. This information is included to help the reader locate the exact portion of text themselves. It is unnecessary to include this information when you’re simply referring to another source.

Examples of APA in-text citations:

“Well, you’re about to enter the land of the free and the brave. And I don’t know how you got that stamp on your passport. The priest must know someone” (TĂłibín, 2009, p. 52).
Student teachers who use technology in their lessons tend to continue using technology tools throughout their teaching careers (Kent & Giles, 2017, p. 12).

If including the author’s name in the sentence, place the year in the parentheses directly next to his or her name. Add the page number at the end, unless it’s a source without any pages or paragraph numbers (See Section 8.10 of the Publication manual for more details).

In-text citation APA example:

According to a study done by Kent and Giles (2017), student teachers who use technology in their lessons tend to continue using technology tools throughout their teaching careers.

The full references, or citations, for these sources can be found on the last part of a research project, titled the “References.”

Here’s how to create in-text citations for specific amounts of authors:

APA citation with no author

When the source lacks an author’s name, place the title, year, and page number (if available) in the text. The title should be in italics if it sits alone (such as a movie, brochure, or report). If the source is part of a whole (as many web pages and articles are), place the title in quotation marks without italics (See Section 8.14 of the Publication manual ).

Structure of an APA format citation in the text narratively, with the author's name missing:

Title of Source (Year) or “Title of Source” (Year)

Structure of an APA style format citation, in parentheses at the end of the sentence, with the author’s name missing: (Title of Source, Year) or (“Title of Source,” Year)

Structure for one author

In the text, narratively: Last name of Author (Year)...(page number).

In parentheses, at the end of the sentence: (Last name of Author, Year, page number).

Structure for two authors

Place the authors in the order they appear on the source. Only use the ampersand in the parenthetical citations (see Section 8.17 of the Publication manual ). Use ‘and’ to separate the author names if they’re in the text of the sentence.

In the text, narratively: Last name of Author 1 and Last name of Author 2 (Year)....(page number).

In parentheses, at the end of the sentence: (Last name of Author 1 & Last name of Author 2, Year, page number).

Structure for three or more authors

Only include the first listed author’s name in the first and any subsequent citations. Follow it with et al.

(Last name Author 1 et al., Year, page number)

(Agbayani et al., 2020, p. 99)

Last name of Author 1 et al. (Year)...(page).

Agbayani et al. (2020)...(p. 99)

One author, multiple works, same year

What do you do when you want to cite multiple works by an author, and the sources all written in the same year?

Include the letters ‘a’ ‘b’ ‘c’ and so on after the year in the citation.

(Jackson, 2013a)

Jackson (2013a)

Writers can even lump dates together.

Example: Jackson often studied mammals while in Africa (2013a, 2013b).

On the APA reference page, include the same letters in the full references.

Groups and organizations

Write out the full name of the group or organization in the first citation and place the abbreviation next to it in brackets. If the group or organization is cited again, only include the abbreviation. If it doesn’t have an abbreviation associated with it, write out the entire organization’s name each and every time (see Section 8.21 of the Publication manual ).

First APA citation for an organization with an abbreviation: (World Health Organization [WHO], Year)

World Health Organization (WHO, Year)

Notice in the example directly above, the name of the organization is written out in full in the text of the sentence, and the abbreviation is placed in parentheses next to it.

Subsequent APA citations in the text for an organization with an abbreviation: (WHO, Year) OR WHO (Year)

All citations in the text for an organization without an abbreviation: (Citation Machine, Year) or Citation Machine (Year)

One in-text citation, multiple works

Sometimes you’ll need to cite more than one work within an in-text citation. Follow the same format (author, year) format but place semicolons between works (p. 263).

(Obama, 2016; Monroe et al., 1820; Hoover & Coolidge, 1928)

Reference list citation components

References display the full information for all the citations found in the body of a research project.

Some things to keep in mind when it comes to the references:

  • All references sit together on their own page, which is usually the last page(s) of a paper.
  • Title the page ‘References’
  • Place ‘References’ in the center of the page and bold it. Keep the title in the same font and size as the references. Do not italicize, underline, place the title in quotation marks, or increase the font size.
  • The entire page is double spaced.
  • All references are listed in alphabetical order by the first word in the reference, which is usually the author’s last name. If the source lacks an author, alphabetize the source by the title (ignore A, An, or The)
  • All references have a hanging indent, meaning that the second line of text is indented in half an inch. See examples throughout this guide.
  • Remember, each and every citation in the text of the paper MUST have a full reference displayed in the reference list. The citations in the text provide the reader with a quick glimpse about the sources used, but the references in the reference list provide the reader with all the information needed to seek out the source themselves.

Learn more about each component of the reference citation and how to format it in the sections that follow. See an APA sample paper reference list at the end of this entire section.

Author’s names

The names of authors are written in reverse order. Include the initials for the first and middle names. End this information with a period (see Section 9.8 of the Publication manual ).

Format: Last name, F. M.

  • Angelou, M.
  • Doyle, A. C.

Two or more authors

When two or more authors work together on a source, write them in the order in which they appear on the source. You can name up to 20 authors in the reference. For sources with 2 to 20 authors, place an ampersand (&) before the final author. Use this format:

Last name, F. M., & Last name, F. M.

Last name, F. M., Last name, F. M., Last name, F. M., Last name, F. M., & Last name, F. M.

Kent, A. G., Giles, R. M., Thorpe, A., Lukes, R., Bever, D. J., & He, Y.

If there are 21 or more authors listed on a source, only include the first 19 authors, add three ellipses, and then add the last author’s name.

Roberts, A., Johnson, M. C., Klein, J., Cheng, E. V., Sherman, A., Levin, K. K. , ...Lopez, G. S.

If you plan on using a free APA citation tool, like the one at CitationMachine.com, the names of the authors will format properly for you.

###No authors

If the source lacks an author, place the title in the first position in the reference (Section 9.12 of the Publication manual ). When the source’s title begins with a number (Such as 101 Dalmatians ), place the reference alphabetically as if the number was spelled out. 101 Dalmatians would be placed in the spot where ‘One hundred’ would go, but keep the numbers in their place.

Additionally, if the title begins with the words ‘A’, ‘An,’ or ‘The,’ ignore these words and place the title alphabetically according to the next word.

See the “Titles” section below for more information on formatting the title of sources.

###Corporate/Organization authors

On an APA reference page, corporate authors are always written out in full. In the text of your paper, you may have some abbreviations (such as UN for United Nations), but in the full references, always include the full names of the corporation or organization (following Section 9.11 of the official Publication manual ).

%%United Nations. (2019). Libya: $202 million needed to bring life-saving aid to half a million people hit by humanitarian crisis. https://news.un.org/en/story/2019/02/1031981

Publication date & retrieval date

Directly after the author’s name is the date the source was published. Include the full date for newspapers and magazine articles, and only the year for journals and all other sources. If no date is found on the source, include the initials, n.d. for “no date.”

%% Narducci, M. (2017, May 19). City renames part of 11th Street Ed Snider Way to honor Flyers founder. The Philadelphia Inquirer . http://www.philly.com/

If using our APA Citation Machine, our citation generator will add the correct format for you automatically.

Giving a retrieval date is not needed unless the online content is likely to be frequently updated and changed (e.g., encyclopedia article, dictionary entry, Twitter profile, etc.).

%%Citation Machine [@CiteMachine]. (n.d.). Tweets [Twitter profile]. Twitter. Retrieved October 10, 2019, from https://twitter.com/CiteMachine

When writing out titles for books, articles, chapters, or other non-periodical sources, only capitalize the first word of the title and the first word of the subtitle. Names of people, places, organizations, and other proper nouns also have the first letter capitalized. For books and reports, italicize the title in the APA citation.

Strange case of Dr. Jekyll and Mr. Hyde.

Roots: The saga of an American family.

For articles and chapters in APA referencing, do not italicize the title.

Wake up the nation: Public libraries, policy making, and political discourse.

For newspapers, magazines, journals, newsletters, and other periodicals, capitalize the first letter in each word and italicize the title.

The Seattle Times.

A common question is whether to underline your title or place it in italics or quotation marks in the reference list. Here’s a good general rule: When a source sits alone and is not part of a larger whole, place the title in italics. If the source does not sit alone and is part of a larger whole, do not place it in italics.

Books, movies, journals, and television shows are placed in italics since they stand alone. Songs on an album, episodes of television shows, chapters in books, and articles in journals are not placed in italics since they are smaller pieces of larger wholes.

The Citation Machine citation generator will format the title in your citations automatically.

Additional information about the title

If you feel it would be helpful to include additional information about the source type, include a descriptive noun or two in brackets immediately following the title. Capitalize the first letter.

%%Kennedy, K., & Molen, G. R. (Producers), & Spielberg, S. (Director). (1993). Jurassic Park [Film]. USA: Universal.

Besides [Film], other common notations include:

  • [Audio podcast]
  • [Letter to the editor]
  • [Television series episode]
  • [Facebook page]
  • [Blog post]
  • [Lecture notes]
  • [PowerPoint presentation]
  • [Video file]

If you are using Citation Machine citing tools, additional information about the title is automatically added for you.

Publisher information

For books and reports, include the publisher name but not the location (see Section 9.29 of the Publication manual ). Older editions of the style required the city, state and/or country, but this hasn't been the case since the 7th edition was released.

It is not necessary to include the entire name of the publisher. It is acceptable to use a brief, intelligible form. However, if Books or Press are part of the publisher’s names, keep these words in the reference. Other common terms, such as Inc., Co., Publishers, and others can be omitted.

For newspapers, journals, magazines, and other periodicals, include the volume and issue number after the title. The volume number is listed first, by itself, in italics. The issue number is in parentheses immediately after it, not italicized. There is no space after the closing parenthesis and before the volume number.

%%Giannoukos, G., Besas, G., Hictour, V., & Georgas, T. (2016). A study on the role of computers in adult education. Educational Research and Reviews , 11 (9), 907-923. https://doi.org/10.5897/ERR2016.2688

After including the publisher information, end this section with a period.

Perseus Books.

Electronic source information:

For online sources, the URL or DOI (Direct Object Identifier) are included at the end of an APA citation.

DOI numbers are often created by publishers for journal articles and other periodical sources. They were created in response to the problem of broken or outdated links and URLs. When a journal article is assigned a DOI number, it is static and will never change. Because of its permanent characteristic, DOIs are the preferred type of electronic information to include in APA citations. When a DOI number is not available, include the source’s URL (see Section 9.34 in the Publication manual ).

For DOIs, include the number in this format:

http://doi.org/xxxx

For URLs, type them in this format:

http:// or https://

Other information about electronic sources:

  • If the URL is longer than a line, break it up before a punctuation mark.
  • Do not place a period at the end of the citation/URL.
  • It is unnecessary to include retrieval dates, unless the source changes often over time (like in a Wikipedia article).
  • It is not necessary to include the names of databases

If using the Citation Machine APA citation website autocite features, the online publication information will be automatically replaced by the DOI. The Citation Machine APA template will properly cite your online sources for you.

Make sure you run your completed paper through the Citation Machine Plus smart proofreader, which scans for grammar, spelling, and plagiarism. Whether it’s an adjective , verb , or pronoun out-of-place, our technology helps edits your paper for you!

Annotated bibliographies:

An APA annotated bibliography is a full bibliography that includes a small note for each reference citation. Each note should be short (1-2 paragraphs) and contain a summary or your evaluation about each source. When creating your citations on CitationMachine.net, there is a field at the bottom of each form to add your own annotations.

Follow the publication manual guidelines on paper format and writing style. Let your instructor guide other details about your annotations. Still confused? Read our guide on annotated bibliographies .

These types of projects look different depending on the style you’re using. Use the link at the top of the page to access resources related to the Modern Language Association’s style. Here’s information related to Chicago citation style .

Page formatting

Need help with the design and formatting of your paper? Look no further! This section provides the ins and outs of properly displaying the information in your APA essay.

  • Times New Roman, 12-point size.
  • Calibri, Arial, or Georgia, 11-point size
  • Lucida, Sans Unicode, or Computer Modern, 10-point size
  • Indents = Every paragraph should start with an indent.
  • Margins = 1 inch around the entire document
  • Spacing = Double space everything!

Arrange your pages in this order:

  • Page 1 - APA Title Page (see below for information on the title page)
  • Page 2 - Abstract (If your professor requests one)
  • Page 3 - First page of text
  • References begin on their own page. Include the list of references on the page after the text.
  • Tables and figures

Keep in mind that the order above is the recommendation for papers being submitted for peer review. If you’re writing an APA style paper for a class, your professor may be more lenient about the requirements. Also, if you’re submitting your paper for a specific journal, check the requirements on the journal’s website. Each journal has different rules and procedures.

Just a little nudge to remind you about the Citation Machine Plus smart proofreader. Whether it’s a conjunction or interjection out of place, a misspelled word, or an out of place citation, we’ll offer suggestions for improvement! Don’t forget to check out our APA citation maker while you’re at it!

Running heads

In older editions of APA, running heads were required for all papers. Since the 7th edition, that’s changed.

  • Student paper: No running head
  • Professional paper: Include a running head

The running head displays the title of the paper and the page number on all pages of the paper. This header is found on every page of a professional paper (not a student paper), even on the title page (sometimes called an APA cover page) and reference list (taken from Section 2.8 of the Publication manual ).

It's displayed all in capital letters at the top of the page. Across from the running head, along the right margin, is the page number.

  • Use the header feature in your word processor. Both Google Docs and Word have these features available.
  • Use one for the recommended fonts mentioned under "Page formatting."

Title pages

A title page, sometimes called an APA cover page, graces the cover of an essay or paper. An APA title page should follow rules from Section 2.3 of the official Publication manual and include:

  • Page number, which is page 1
  • Use title case and bold font
  • The title should be under 12 words in length
  • The title should be a direct explanation of the focus of the paper. Do not include any unnecessary descriptors such as “An Analysis of

  • Course number and/or class name
  • Name of your instructor, including their preferred honorifics (e.g., PhD, Dr., etc.)
  • Paper’s due date
  • If this is a professional paper, also include a running head. If this is a student paper, do not include one.

Follow the directions for the running head and page number in the section above. Below the running head, a few lines beneath, and centered in the middle of the page, should be the title. The next line below is the author’s name(s), followed by the name of the school or institution, the class or course name, your instructor’s name, and the paper’s due date.

All components on this page should be written in the same font and size as the rest of your paper. Double space the title, names, name of school or institution, and all other information on the page (except for the running head and page number).

An abstract briefly but thoroughly summarizes dissertation contents. It’s found in the beginning of a professional paper, right after the title page. Abstracts are meant to help readers determine whether to continue reading the entire document. With that in mind, try to craft the lead sentence to entice the reader to continue reading.

Here are a few tips:

  • Be factual and keep your opinions out. An abstract should accurately reflect the paper or dissertation and should not involve information or commentary not in the thesis.
  • Communicate your main thesis. What was the examined problem or hypothesis? A reader should know this from reading your abstract.
  • Keep it brief. Stick to the main points and don’t add unnecessary words or facts. It should not exceed 250 words.
  • Consider your paper’s purpose. It’s important to cater your abstract to your paper type and think about what information the target audience for that paper type would want. For example, an empirical article may mention methodology or participant description. A quantitative or qualitative meta-analysis would mention the different variables considered and how information was synthesized.
  • Use verbs over noun equivalents, and active voice. Example: “There was research into
” becomes “We researched
”

Formatting guidelines:

  • The abstract goes after the title page.
  • It should have the same font (size and type) as the rest of the paper.
  • It should stick to one page.
  • Double-space all page text.
  • Center and bold the word “Abstract” at the top of the paper.
  • Don’t indent the first line of the abstract body. The body should also be in plain text.
  • For the keywords, place it on the line after the abstract and indent the first line (but not subsequent lines). The word “Keywords:” is capitalized, italicized, and followed by a colon. The actual keywords are sentence case and in plan font.
  • List each keyword one after the other, and separate them by a comma.
  • After the last keyword, no ending punctuation is needed.

The image shows an example APA abstract page that is formatted using the guidelines described above under the heading Abstracts.

Tables & Figures

If your paper includes a lot of numerical information or data, you may want to consider placing it into a table or a figure, rather than typing it all out. A visual figure or simple, organized table filled with numerical data is often easier for readers to digest and comprehend than tons of paragraphs filled with numbers. Chapter 7 of the Publication manual outlines formatting for tables and figures. Let's cover the basics below.

If you’d like to include a table or figure in your paper, here are a few key pieces of information to keep in mind:

  • At the end of the paper after the APA reference page
  • In the text after it is first mentioned
  • The table first mentioned in the text should be titled ‘Table 1.’ The next table mentioned in the text is ‘Table 2,’ and so on. For figures, it would be 'Figure 1,' 'Figure 2,' and so forth.

The image shows that an APA paper with tables can be organized as follows – 1. Title page, 2. Text of paper, 3. References, 4. Table 1, 5. Table 2.

  • Even though every table and figure is numbered, also create a title for each that describes the information it contains. Capitalize all important words in the title.
  • For tables, do not use any vertical lines, only use horizontal to break up information and headings.
  • Single spacing is acceptable to use in tables and figures. If you prefer double spacing your information, that is okay too.
  • Do not include extra information or “fluff.” Keep it simple!
  • Do not include the same exact information in the paper. Only include the complete information in one area—the table or the text.
  • All tables and figures must be referenced in the text. It is unacceptable to throw a table or figure into the back of the paper without first providing a brief summary or explanation of its relevance.

Example of formatting a table in APA style.

Publication Manual 6th Edition vs 7th Edition

The 6th edition of the Publication Manual of the American Psychological Association was released in 2009. The current 7th edition came out in the fall of 2019 and was designed to be more student focused, provide more guidance on accessibility, and address changes that have developed over the last 10 years.

Below, we’ve listed what we feel are the most relevant changes related to APA format.

Journals and DOIs

DOI stands for “digital object identifier.” Many journal articles use and have a unique DOI that should be included in a full citation.

When including a DOI in a citation, format it as a URL. Do not label it “DOI.” Articles without DOIs from databases are treated as print works. For example:

6th edition:

%%GĂ€nsicke, B. T., Schreiber, M. R., Toloza, O., Fusillo, N. P. G., Koester, D., & Manser, C. J. (2019). Accretion of a giant planet onto a white dwarf star. Nature, 576 (7785), 61–64. doi: 10.1038/s41586-019-1789-8

7th edition:

%%GĂ€nsicke, B. T., Schreiber, M. R., Toloza, O., Fusillo, N. P. G., Koester, D., & Manser, C. J. (2019). Accretion of a giant planet onto a white dwarf star. Nature, 576 (7785), 61–64. https://doi.org/10.1038/s41586-019-1789-8

Citing Books

There are few new guidelines when you are citing a book. First, the publisher location no longer needs to be indicated.

%%Zack, P. O. (2001). The shoals of time. Bloomington, IN: First Books Library.

%%Zack, P. O. (2001). The shoals of time. First Books Library.

Second, the format of an ebook (e.g., Kindle, etc.) no longer needs to be indicated.

%%Niven, J. (2012). Ada Blackjack: A true story of survival in the Arctic [Kindle].

%%Niven, J. (2012). Ada Blackjack: A true story of survival in the Arctic .

Lastly, books from research databases without DOIs are treated the same as print works.

When using a URL in a citation, you no longer need to include the term “Retrieved from” before URLs (except with retrieval dates). The font should be blue and underlined, or black and not underlined.

6th Edition:

%%Flood, A. (2019, December 6). Britain has closed almost 800 libraries since 2010, figures show. The Guardian . Retrieved from https://www.theguardian.com/books/2019/dec/06/britain-has-closed-almost-800-libraries-since-2010-figures-show

7th Edition:

%%Flood, A. (2019, December 6). Britain has closed almost 800 libraries since 2010, figures show. The Guardian . https://www.theguardian.com/books/2019/dec/06/britain-has-closed-almost-800-libraries-since-2010-figures-show

Within a full APA citation, you may spell out up to 20 author names. For two to 20 authors, include an ampersand (&) before the name of the last author. For sources with 21 or more authors, structure it as follows:

Structure: First 19 authors’ names, . . . Last author’s name.

7th edition 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. K., Taylor, Z., Filmore, M., Pierce, F., Buchanan, J., Lincoln, A., Johnson, A., Grant, U. S., Hayes, R. B., Garfield, . . . Trump, D.

When creating an in-text citation for a source with 3 or more authors, use “et al.” after the first author’s name. This helps abbreviate the mention.

6th Edition: (Honda, Johnson, Prosser, Rossi, 2019)

7th Edition: (Honda et al., 2019)

Tables and Figures

Instead of having different formats for tables and figures, both use one standardized format. Now both tables and figures have a number, a title, name of the table/figure, and a note at the bottom.

What is a Citation?

A citation is the basic information required to identify and locate a specific source, e.g. book, book chapter, article, website, video, etc.

What is a Citation Style?

Different academic disciplines have specific guidelines for organizing material and citing sources. These rules are published as style manuals . While each citation system is distinct, the underlying rationale is the same–to facilitate written communication among members in a scholarly community.

Parts of a Citation *

  • Book: Author Name . Title . Publisher, Year. 

Example: Macfarlane, Bruce. Researching with Integrity: The Ethics of Academic Enquiry . Routledge, 2009. 

  • Book Chapter: Author Name. “Chapter Title.” Book Title. Editor, Publisher, Year, Chapter Page Numbers.

Example: Tan, Amy. “Yes and No.” The Genius of Language: Fifteen Writers Reflect on Their Mother Tongues, edited by Wendy Lesser, Pantheon Books, 2004, pp. 25-34.

  • Journal Article: Author Name . “Article Title.” Journal Title, Volume Number, Issue Number , Year, Article Page Numbers.

Example: Hess, Mickey. “Was Foucault A Plagiarist? Hip-Hop Sampling And Academic Citation.” Computers & Composition, vol. 23, no. 3, 2006, pp. 280-295.

  • Website: Author Name. “Title of Page/Work.” Title of Website, Date of Publication, Location.

Example: Calonia, Jennifer. “How to Avoid Plagiarism.” Grammerly Blog, 21 Aug 2019, https://www.grammarly.com/blog/5-most-effective-methods-for-avoiding-plagiarism .

*The order and punctuation of the citation components are dictated by the style you use (above are formatted in MLA).

What is a DOI?

Digital Object Identifiers (DOIs) are unique identifiers that may be assigned to published articles and other works. Their purpose is ensure persistent access to online content. If a DOI is available, you should include it in your citation.

😕 What is an MLA Citation Generator?

An MLA citation generator is a software tool designed to automatically create academic citations in the Modern Language Association (MLA) citation format. The generator will take information such as document titles, author, and URLs as in input, and output fully formatted citations that can be inserted into the Works Cited page of an MLA-compliant academic paper.

The citations on a Works Cited page show the external sources that were used to write the main body of the academic paper, either directly as references and quotes, or indirectly as ideas.

đŸ‘©â€đŸŽ“ Who uses an MLA Citation Generator?

MLA style is most often used by middle school and high school students in preparation for transition to college and further education. Ironically, MLA style is not actually used all that often beyond middle and high school, with APA (American Psychological Association) style being the favored style at colleges across the country.

It is also important at this level to learn why it's critical to cite sources, not just how to cite them.

🙌 Why should I use a Citation Generator?

Writing citations manually is time consuming and error prone. Automating this process with a citation generator is easy, straightforward, and gives accurate results. It's also easier to keep citations organized and in the correct order.

The Works Cited page contributes to the overall grade of a paper, so it is important to produce accurately formatted citations that follow the guidelines in the official MLA Handbook .

⚙ How do I use MyBib's MLA Citation Generator?

It's super easy to create MLA style citations with our MLA Citation Generator. Scroll back up to the generator at the top of the page and select the type of source you're citing. Books, journal articles, and webpages are all examples of the types of sources our generator can cite automatically. Then either search for the source, or enter the details manually in the citation form.

The generator will produce a formatted MLA citation that can be copied and pasted directly into your document, or saved to MyBib as part of your overall Works Cited page (which can be downloaded fully later!).

MyBib supports the following for MLA style:

  • Additional Help

Zotero allows you to quickly create standalone bibliographies, insert citations directly into documents, and automatically generate bibliographies from those citations. Over 8,000 citation styles are supported.

Standalone Bibliographies

Standalone bibliographies are useful if you need to create a bibliography that is not associated with text that contains in-text citations, like an annotated bibliography, or if you wrote a paper using in-text citations that are not linked to your Zotero Library. You can create standalone bibliographies from an entire collection or from individually selected items within a collection.

Citing an Entire Collection:

  • In the Zotero desktop application, right click on the collection you want to cite.
  • Select Create Bibliography from Collection.
  • Don't see the style you want? To add styles, click the "Manage Styles..." link below the citation style box, then click the "Get additional styles..." link and search for the style you want to add.
  • "Citations" will format your items as in-text citations.
  • "Bibliography" will format your items as a full reference citation.
  • Under Output Method, select the Copy to Clipboard option.
  • Paste your bibliography into a word processor document.

Citing Individual Items:

  • In the Zotero desktop application, open the collection containing the items you want to cite.
  • Select the item you want to cite (hold the Ctrl button to select multiple). Selected items will be highlighted.
  • Right click on one of the highlighted items.
  • Select Create Bibliography from Items.

Word Processor Plugins

  • Google Docs
  • Microsoft Word

Google Docs works with Zotero to help you quickly add properly formatted citations and bibliographies to your documents.

Google Docs - Cite While You Write:

  • The Google Docs plugin is bundled with the Zotero Connector and should be automatically installed when you download the Connector .
  • Open your Google Docs document and the Zotero desktop application. Both need to remain open while using the Google Docs plugin.
  • In Google Docs, the Zotero button is located in the top tool bar.

Adding In-Text Citations:

  • Place the cursor where you want the in-text citation to be added.
  • From the Zotero drop down menu, select Add/Edit Citation.
  • The document's citation style can be changed later on.
  • As you type, items from your library will appear. Select the correct item.
  • Once selected, the item will display in the search bar in the format that will be added to your document.
  • Multiple items can be included in the same in-text citation. Add all the items you want to cite to the search bar.
  • To edit the in-text citation (i.e. omit author name or add page number), click on the formatted citation in the search bar.
  • Once you have added and edited your citations, press the Enter key. Your formatted in-text citation will be added to the text.

Note: If you have a large number of items in your library, you might prefer Zotero's classic Add Citation view, which allows you to view all of your items without using the search bar. Follow these classic view set up instructions to make the switch. For help using classic view, see Zotero's Using the Classic View Citation Window documentation.

Adding a Bibliography:

To create a bibliography, you must have at least one in-text citation in the document that is linked to your Zotero library.

  • Place the cursor where you want the bibliography to be added.
  • From the Zotero drop down menu, select Add/Edit Bibliography.
  • The bibliography will be automatically generated in your selected citation style.
  • If you add or remove in-text citations from your document, select Refresh from the Zotero drop down menu to update the bibliography.

Word's Zotero plugin can be used to easily add citations and bibliographies to your Word documents, with minimal disruption to your workflow.

Word - Cite While You Write:

  • The Word plugin is bundled with Zotero and should be automatically installed when you use Zotero for the first time.
  • Open your Word document and the Zotero desktop application. Both need to remain open while using the Word plugin.
  • In Word, select the Zotero tab from the top tool bar.
  • From the Zotero tab, select the Add/Edit Citation icon.
  • From the Zotero tab, select the Add/Edit Bibliography icon.
  • If you add or remove in-text citations from your document, select the Refresh button in the Zotero tab to update the bibliography.
