Include a reference list at the end of your paper. The list should contain a full citation for each source included among your in-text citations.
The references list should begin on a new page at the end of your paper with the word "References" bold and centered at the top of the page.
Organize citations alphabetically by the first word. Usually this will be the author's last name, but, if the source has no author, you'll use the title of the source.
The information these full citations should include depends on the type of source you're citing - for example, whether it's a book, an encyclopedia entry, or an article in a periodical. You'll find the formulas for the most common source types in our APA 7 Quick Guide. If you're having difficulty identifying the type of source you're using, consult a librarian.
Use an in-text citation to acknowledge that you are quoting or paraphrasing another author's words, ideas or data in the text of your research paper.
Add in-text citations in parentheses at the end of the sentence but before the final punctuation (like this).
Each in-text citation should include all of the following elements, separated by commas:
the last name of the author(s)
the year of publication
the number of the page(s) where you found the information, preceded by the abbreviation p. for a single page or pp. for a range of pages
example: (Rivera, 2019, p. 28)
You've used the author's name in the sentence, for example when introducing a quote
Include the year of publication in parentheses after the author's name and the page number(s) in separate parentheses at the end of the sentence.
example:Rivera (2019) asserts that... (p. 28).
The source has no author
Use the title of the source in place of the author's name. Titles of longer works such as books should be italicized. Titles of shorter works, such as a chapter from a book or an article from a magazine or journal should be placed in quotation marks. All titles should appear in standard title case (i.e. capitalize all major words).
example:("Using Citations," 2019, p. 28)
The source has two authors
Use the last names of both authors, separated by an ampersand (&)
example:(Rivera & Rodriguez, 2019, p. 28)
The source has three or more authors
Use the last name of the first author followed by "et al."
example:(Rivera et al., 2019, p. 28)
There's no publication date given for the source
Use the abbreviation n.d. (for "no date") in place of the year
example: (Rivera, n.d., p. 28).
The source doesn't have numbered pages
Use the number of the paragraph the information came from preceded by the abbreviation para. in place of the page number
example:(Rivera, 2019, para. 4)
Step 3: Double-check your paper and citation formatting
The APA Manual dictates the rules for formatting your in-text citations, References page, and your final research paper.
