In-Text Citations

APA Style uses parenthetical author-date citations. After summarizing or quoting a source, add parentheses containing the author's last name, the year of publication, and the page number of the work.

Example: "The quick brown fox jumped over the lazy dog" (Seuss, 2007, pp. 7-8).

If you use more than one work by the same author, use the letters a, b, etc., after the year.

Example: "The quick brown fox jumped over the lazy dog" (Seuss, 2007a, pp. 7-8).

If more than one author has the same last name, add their first initial.

Example: "The quick brown fox jumped over the lazy dog" (D. Seuss, 2007, pp. 7-8).

If two or more authors wrote the work, see the chart below.

If using the author's name in your text, do not include it in the parentheses.

Example: In his scholarly study, Dr. Seuss observed that "the quick brown fox jumped over the lazy dog" (2007, pp. 7-8).
Example: In 2007, Dr. Seuss suggested that "the quick brown fox jumped over the lazy dog" (pp. 708).

If no author name is available, use the first few words of the reference list entry (usually the title). Use quotation marks around titles of articles or web pages and italicize titles of books, periodicals, etc.

Example: "The quick brown fox jumped over the lazy dog" (Fox in Socks, 2007).

If no pagination information is available, use paragraph numbers instead.

Example: "The quick brown fox jumped over the lazy dog" (Seuss, 2007, para. 5).

Note: When paraphrasing or mentioning another work, it is helpful to still provide pagination information if the source text is long or difficult, or if it would help the reader find the text being paraphrased.
