APA Style refers to the rules found in the Publication Manual of the American Psychological Association. APA Style is most often used in the social sciences, business, education and sometimes science and medicine.
APA Style consists of two main parts: (1) in-text citations (sometimes called parenthetical citations); and (2) a reference list (also known as a bibliography).
