This guide introduces the APA Style.
The APA (American Psychological Association) Style is a set of rules for formatting a paper. It includes spacing, headers, page numbering, and how citations should look.
These rules are published in the Publication Manual of the American Psychological Association.
Social Science and Science classes commonly use this style for papers. Be aware that there are other styles, such as MLA, Turabian, and Chicago. These styles have alternate rules for formatting a paper.
