"American Psychological Association (APA) Citation Style: APA citation style is established by the American Psychological Association. It is mainly used for psychology, education, and social science bibliographies. APA style specifies the names and order of headings, formatting, and organization of citations and references, and the arrangement of tables, figures, footnotes, and appendices, as well as other manuscript and documentation features. It uses parenthetical citation within the text, listing the author’s surname and the year of publication of the work, which is more or less same as that of MLA style’s parenthetical citations. It lists sources at the end of the paper, on a References Page. Listing electronic sources of information is more detailed in APA style than in MLA style. APA style uses Harvard referencing, also known as the author-date system of citations and parenthetical referencing, keyed to a subsequent list of References."
