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: On pages 65-66, 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, 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."

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."). Introduce the quotation with a signal phrase that includes the author's last name followed by the date of publication in parentheses.

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.

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. The parenthetical citation should come after the closing punctuation mark.

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).
