What is Chicago Citation Style

What is Chicago Citation Style

Chicago is a documentation style that has been published by the Chicago University Press since 1906. This citation style incorporates rules of grammar and punctuation common in American English. Typically, the Chicago style presents two basic documentation systems: (1) notes and bibliography and (2) author-date. Choosing between the two often depends on the subject matter and the nature of sources cited, as each system is favored by different groups of scholars.

The notes and bibliography style is preferred by many in the humanities, including those in literature, history, and the arts. This style presents bibliographic information in notes and, often, a bibliography.

The author-date style has long been used by those in the physical, natural, and social sciences. In this system, sources are briefly cited in the text, usually in parentheses, by the author’s last name and date of publication. The short citations are amplified in a list of references, where full bibliographic information is provided.
