In-Text Citations: The Basics

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 This material may not be published, reproduced, broadcast, rewritten, or redistributed without permission.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.

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.

Table of Contents

Journal article from library database with doi - one author, journal article from library database with doi - multiple authors, journal article from a website - one author.

Journal Article- No DOI

Note: All citations should be double spaced and have a hanging indent in a Reference List.

A "hanging indent" means that each subsequent line after the first line of your citation should be indented by 0.5 inches.

This Microsoft support page contains instructions about how to format a hanging indent in a paper.

• APA 7th. ed. Journal Article Reference Checklist

If an item has no author, start the citation with the article title.

When an article has one to twenty authors, all authors' names are cited in the References List entry. When an article has twenty-one or more authors list the first nineteen authors followed by three spaced ellipse points (. . .) , and then the last author's name. Rules are different for in-text citations; please see the examples provided.

Cite author names in the order in which they appear on the source, not in alphabetical order (the first author is usually the person who contributed the most work to the publication).

Italicize titles of journals, magazines and newspapers. Do not italicize or use quotation marks for the titles of articles.

Capitalize only the first letter of the first word of the article title. If there is a colon in the article title, also capitalize the first letter of the first word after the colon.

If an item has no date, use the short form n.d. where you would normally put the date.

Volume and Issue Numbers

Italicize volume numbers but not issue numbers.

Retrieval Dates

Most articles will not need these in the citation. Only use them for online articles from places where content may change often, like a free website or a wiki.

Page Numbers

If an article doesn't appear on continuous pages, list all the page numbers the article is on, separated by commas. For example (4, 6, 12-14)

Library Database

Do not include the name of a database for works obtained from most academic research databases (e.g. APA PsycInfo, CINAHL) because works in these resources are widely available. Exceptions are Cochrane Database of Systematic Reviews, ERIC, ProQuest Dissertations, and UpToDate.

Include the DOI (formatted as a URL: https://doi.org/...) if it is available. If you do not have a DOI, include a URL if the full text of the article is available online (not as part of a library database). If the full text is from a library database, do not include a DOI, URL, or database name.

In the Body of a Paper

Books, Journals, Reports, Webpages, etc.: When you refer to titles of a “stand-alone work,” as the APA calls them on their APA Style website, such as books, journals, reports, and webpages, you should italicize them. Capitalize words as you would for an article title in a reference, e.g., In the book Crying in H Mart: A memoir , author Michelle Zauner (2021) describes her biracial origin and its impact on her identity.

Article or Chapter: When you refer to the title of a part of a work, such as an article or a chapter, put quotation marks around the title and capitalize it as you would for a journal title in a reference, e.g., In the chapter “Where’s the Wine,” Zauner (2021) describes how she decided to become a musician.

The APA Sample Paper below has more information about formatting your paper.

Basic structure for an article: 

Author, a. a., & author, b. b. (year). title of article in non-italics: capital letter also for subtitle.  journal title in italics, volume# (issue#), pg#-pg#. https://doi.org/10.xxxxxxxx.

You can leave out any parts that you don't have, like a DOI, the volume, issue, or page numbers.

Online or Print, with DOI (p. 316+ in Manual)

On all article citations, whether you read online or print, include the Digital Object Identifier (DOI) if available.  The DOI is like a digital thumbprint: its unique and permanent numbers and letters help identify it. It is typically on the first or last page of the article. It may also be listed in the  CrossRef Database . If you are having trouble finding the DOI,  ask a librarian .  If there is no DOI, see  this example . 

Note  that as of March 2017,  CrossRef  and  APA  both recommend that DOIs be formatted as such:  https://doi.org/10.xxxx/xxxxx  with no period at the end.  

In-text Citation

After the report title, include any report number if available and the Source, which can be thought of like the Publisher of a book.

Group Author or Government Report (see p. 329-330 in Manual)

In governmental reports, you can have multiple "levels," or offices/departments, in the Source element, separated by a comma.

The  Author  is the office that was most directly responsible for creating the content, and any parent offices are the  Source . If you aren't sure which office created the content, look on Google or on their general webpage to figure out the structure -- which office is "under" another office?

Parenthetical Citation :  Law enforcement agencies have started to increase the use of drones since 2016 for a variety of purposes (Police Executive Research Forum, 2020).

No Author, Volume, or Issue Number 

Remember that APA encourages researchers to use the name of a corporate author, a governmental organization, an office, a department, etc. as the author (see  an example like this) .

However, if no author can be found, as is sometimes the case with newspaper and magazine articles, begin the citation with the title of the article.
