The University of Chicago developed the Chicago citation style. Many people in the humanities, such as history, literature, and the arts, favor the Notes and Bibliography style. In science, researchers usually follow the Publication date format. In the social sciences, People sometimes use the Textual format. Note: The Chicago citation style is not the only way to cite sources; however, it is the most common method used by historians in particular. Note: There are several other citation styles that are less commonly used but include important information about where you found your source. These include the APA (American Psychological Association) citation style, which is useful for citing books, articles, and conference presentations; the Vancouver (University of British Columbia) style, which is best used with scholarly journals that require a formal reference list; and the ATLA (American Theological Library Association) style, which is recommended for biblical scholars.
