In-Text Citations: The Basics
APA (American Psychological Association) style is most commonly used to cite sources within the social sciences. This resource, revised according to the 6th edition, second printing of the APA manual, offers examples for the general format of APA research papers, in-text citations, endnotes/footnotes, and the reference page. For more information, please consult the Publication Manual of the American Psychological Association, (6th ed., 2nd printing).

Reference citations in text are covered on pages 169-179 of the Publication Manual. What follows are some general guidelines for referring to the works of others in your essay.
Note: APA style requires authors to use the past tense or present perfect tense when using signal phrases to describe earlier research, for example, Jones (1998) found or Jones (1998) has found...
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, for example, (Jones, 1998), and a complete reference 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. 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."
- Italicize the titles of longer works such as books, edited collections, movies, television series, documentaries, or albums: The Closing of the American Mind; The Wizard of Oz; Friends.
- Put quotation marks around the titles of shorter works such as journal articles, articles from edited collections, television series episodes, and song titles: "Multimedia Narration: Constructing Possible Worlds;" "The One Where Chandler Can't Cry."
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."). Introduce the quotation with a signal phrase that includes the author's last name followed by the date of publication in parentheses.
According to Jones (1998), "Students often had difficulty using APA style, especially when it was their first time" (p. 199).
Jones (1998) found "students often had difficulty using APA style" (p. 199); what implications does this have for teachers?
If the author is not named in a signal phrase, place the author's last name, the year of publication, and the page number in parentheses after the quotation.
She stated, "Students often had difficulty using APA style" (Jones, 1998, p. 199), but she did not offer an explanation as to why.
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. The parenthetical citation should come after the closing punctuation mark.
Jones's (1998) study found the following:
Students often had difficulty using APA style, especially when it was their first time citingsources. This difficulty could be attributed to thefact that many students failed to purchase astyle manual or to ask their teacher for help. (p. 199)
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, but APA guidelines encourage you to also provide the page number (although it is not required.)
According to Jones (1998), APA style is a difficult citation format for first-time learners.
APA style is a difficult citation format for first-time learners (Jones, 1998, p. 199).
Why we use parenthetical / in-text citations
Researchers place brief parenthetical descriptions to acknowledge which parts of their paper reference particular sources. Generally, you want to provide the last name of the author and the specific page numbers of the source. If such information is already given in the body of the sentence, then exclude it from the parenthetical citation.
Place the parenthetical citation where there is a pause in the sentence – normally before the end of a sentence or a comma. The in-text citation will differ depending on how much information you provide within the sentence.
Example with author’s name in text:
Johnson argues this point (12-13).
This point had already been argued (Johnson 12-13).
Citing sources with more than one author
If you use sources with the same author surnames, then include a first name initial. If the two sources have authors with the same initials, then include their full names:[su_spacer]
(J. Johnson 12-13).
(John Johnson 12-13).
If there are two or three authors of the source, include their last names in the order they appear on the source:
(Smith, Wollensky, and Johnson 45).
If there are more than three authors, you can cite all the authors with their last name, or you can cite the first author followed by “et al.” Follow what is shown the works cited list.
(Smith et al. 45).
Citing sources without an author
Some sources do not have authors or contributors – for instance, when you cite some websites. Instead, refer to the name of the source in your parenthetical citation in place of the author. Shorten / abbreviate the name of the source but ensure that your reader can easily identify it in your works cited (abbreviate the title starting with the same word in which it is alphabetized). Punctuate with quotations or italicize as you would in its works cited form (a book is italicized; an article is in quotes).
Double agents are still widely in use (Spies 12-15, 17).
With prices of energy at new highs, bikes have been increasingly used (“Alternative Transportation” 89).
Citing part of a work
When citing a specific part of a work, provide the relevant page or section identifier. This can include specific pages, sections, paragraphs or volumes. When the identifier is preceded by an abbreviation or word, place a comma between the identifier and the source reference.
Part of a multivolume work
It is arguably the most innovative period in history (Webster, vol 4).
Chapter within a book (if no specific numbers can be referenced)
The electoral college undermines democracy (Sanders, “Government Injustices”).
Article in a periodical
Allen claims there is an inverse correlation between higher taxes and patriotic feelings worldwide (B2).
When citing a specific page(s) of a multivolume work, precede the page number by the volume number and a colon. Do not separate by a comma.
It was arguably the most innovative period in history (Webster 4:12-15).
Use “par.” or “pars.” when referring to specific paragraphs.
The marketing dollars of big studio films has overshadowed good indie movies (Anderson, pars. 12-34).
Citing group or corporate authors
In your parenthetical citation, cite a corporate author like you would a normal author. Preferably, incorporate the corporate author in your text instead of the parenthetical citation.
Facial transplants pose significant risk to the autoimmune system (American Medical Association 12-43).
As noted by the American Medical Association, facial transplants pose significant risk to the autoimmune system (12-43).
Citing an entire source
When citing an entire work, there are no specific page numbers to refer to. Therefore it is preferable to refer to the source within the text itself with either the author or the title of the source.
Hartford suggests the Internet provides more distractions than it does information.
Citing multiple works by the same author
If you reference more than one source by the same author, distinguish the parenthetical citations by including the name of the source. Use a comma to separate the author from the source.
Wars can be economic catalysts (Friedman, World 77-80).
Industrialized nations are better equipped to rebound from recessions (Friedman, “High Tides” 56).
Citing indirect sources
When an original source is unavailable, then cite the secondhand source – for instance, a lecture in a conference proceedings. When quoting or paraphrasing a quote, write “qtd. in” before the author and pages.
John Murray calls Tim Smith “interesting but egotistical” (qtd. in Jesrani 34).
Citing literary / classic and religious works
For works such as novels, plays and other classic works, it’s helpful to provide further identifying information along with the page information. Do this by adding a semicolon and then the identifying information following the page number.
(Tolstoy 5; pt. 2, ch. 3).
When citing classic poems and plays, replace page numbers with division numbers (part, book, scene, act). The below refers to book 10 line 5. Bear in mind the divisions and the way they are written can vary by source.
Fear plays a role in Homer’s Odyssey (10.5).
The title of books in the Bible and other famous literary works should be abbreviated.
(New Jerusalem Bible, Gen. 2.6-9).
Placing parenthetical citations in direct quotations
When directly quoting a source, place the parenthetical citation after the quote.
Sanders explains that economic woes are due to “the mortgage crisis and poor risk assessment” (20).
Place the parenthetical citation at the end of an indented quotation. There should be no period after the parenthetical citation. The last sentence of the indented quote should look like:
It’s unclear whether multilateral tariffs are disruptive to bilateral talks. (Evert 30-31)
Citing online sources
Generally, follow the same principals of parenthetical citations to cite online sources. Refer to the author, and if possible, a permanent identifier that would be the same for any reader.
The economy will rebound with the new monetary policies (Smith).
Solar power will become the primary source of energy (Williams 2).
Citing online sources with no author
If there is no author, use the title that begins the citation, either the article or website title. Be sure it also takes the same formatting, i.e. articles are in quotes and website titles are italicized. Shorten / abbreviate the name of the source but ensure that your reader can easily identify it in your works cited (abbreviate the title starting with the same word in which it is alphabetized).
Elephants are thought to be one of the smartest mammals (“Smart Elephants”).
Nineteen men and women were convicted (Salem Witchcraft Trials).
Note: Ideally, when citing online sources, try to reference the source within your sentence, with either the author or the title to avoid writing a parenthetical citation.
Where to put the parenthetical citations:
- Place parenthetical citations at the end of the sentence you are paraphrasing and quoting. For example: The destruction of the argentine is due to many socioeconomic factors (Taylor 33).
- Even when quoting, place the parenthetical citations after the quotations.
“Mamma always said stupid is as stupid does” (Gump 89).
When quoting four lines or more, indent every line you are quoting by one inch (or 10 spaces) and do not use quotes.
The use of nuclear weapons in today’s society is strikingly alarming. Though the United States is the only country to employ it in the past, they are at the same time the country that condemns its use the most. While this may seem hypocritical, is it the most proper action for the United States to make as the global leader. (Taparia 9)
