APA relies on an author-date system, in which an abbreviated form of the author's name (last name and first initial) is followed by the date of publication. In APA, writers do not construct bibliographies, as they would in the Humanities, but compile lists of references made within the text. The APA style encourages the quick correlation of references made within the text with those found in the reference list itself. The APA style also gives writers an effective way to compile and summarize the research of others in their own writing.
The following examples follow the Publication Manual of the American Psychological Association, 6th ed. (2010).
