APA style for documentation is widely used in the social sciences. APA style features brief parenthetical citations in the text that correspond to an alphabetical list of references that appear at the end of the work.
On this page, you will find examples on citing some of the most commonly used sources; however, this is by no means an exhaustive list. If you don't find your source type here or if you can have further questions, you can reference the Publication Manual of the American Psychological Association, Seventh Edition, available for in library use at the circulation desk.
