Used in: Humanities and Social Sciences
The Chicago Manual of Style offers two very different methods of citation: the notes and bibliography system and the author-date system. You should always check with your instructor or publisher to find out which style you should use.
The notes and bibliography system is preferred by many working in the humanities, including literature, history, and the arts. In the notes and bibliography system, sources are cited in numbered footnotes or endnotes. Each note corresponds to a raised (superscript) number in the text. Sources are also usually listed in a separate bibliography.
The author-date system is generally used in the social sciences. In the author-date system, sources are briefly cited in the text, usually in parentheses, by author’s last name and year of publication. Each in-text citation matches up with an entry in a reference list, where full bibliographic information is provided.
