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).

Your reference list should appear at the end of your paper. It provides the information necessary for a reader to locate and retrieve any source you cite in the body of the paper. Each source you cite in the paper must appear in your reference list; likewise, each entry in the reference list must be cited in your text.
Your references should begin on a new page separate from the text of the essay; label this page "References" centered at the top of the page (do NOT bold, underline, or use quotation marks for the title). All text should be double-spaced just like the rest of your essay.
- All lines after the first line of each entry in your reference list should be indented one-half inch from the left margin. This is called hanging indentation.
- Authors' names are inverted (last name first); give the last name and initials for all authors of a particular work for up to and including seven authors. If the work has more than seven authors, list the first six authors and then use ellipses after the sixth author's name. After the ellipses, list the last author's name of the work.
- Reference list entries should be alphabetized by the last name of the first author of each work.
- For multiple articles by the same author, or authors listed in the same order, list the entries in chronological order, from earliest to most recent.
- Present the journal title in full.
- Maintain the punctuation and capitalization that is used by the journal in its title.
- For example: ReCALL not RECALL or Knowledge Management Research & Practice not Knowledge Management Research and Practice.
- Capitalize all major words in journal titles.
- When referring to books, chapters, articles, or webpages, capitalize only the first letter of the first word of a title and subtitle, the first word after a colon or a dash in the title, and proper nouns.
- Italicize titles of longer works such as books and journals.
- Do not italicize, underline, or put quotes around the titles of shorter works such as journal articles or essays in edited collections.
- Please note: While the APA manual provides many examples of how to cite common types of sources, it does not provide rules on how to cite all types of sources. Therefore, if you have a source that APA does not include, APA suggests that you find the example that is most similar to your source and use that format. For more information, see page 193 of the Publication Manual of the American Psychological Association, 6th ed., 2nd printing.

Did you know that there’s no such thing as a bibliography in APA Style? It’s a fact! APA Style uses text citations and a reference list, rather than footnotes and a bibliography, to document sources.
A reference list and a bibliography look a lot alike: They’re both composed of entries arranged alphabetically by author, for example, and they include the same basic information. The difference lies not so much in how they look as in what they contain.
A bibliography usually contains all the works cited in a paper, but it may also include other works that the author consulted, even if they are not mentioned in the text. Some bibliographies contain only the sources that the author feels are most significant or useful to readers.
In APA Style, however, each reference cited in text must appear in the reference list, and each entry in the reference list must be cited in text. If you cite only three sources in your paper, your reference list will be very short—even if you had to read 50 sources to find those three gems! (Hopefully, that hard work will pay off on your next assignment.)
The APA Style Experts are often asked to provide the “official APA-approved format” for annotated bibliographies (i.e., bibliographies that contain the author’s comments on each source). As you may have guessed, there isn’t one; APA Style doesn’t use bibliographies of any sort. In addition, though, the reference list in APA Style contains only the information that is necessary to help the reader uniquely identify and access each source. That’s why there is no format for an annotated bibliography in the Publication Manual.
