Chicago Citation Quick Guide
15th Edition (16th Edition was released in 2010, this guide does not reflect the new edition)
The Chicago Manual of Style has two methods of documentation, the humanities style (notes and bibliography) and the author-date style. The humanities style is preferred in literature, history, and the arts. The author-date method is useful in the physical, natural, and social sciences. Sources are cited in the text: (authors last name, publication date, and page number). Details about each reference are listed in the References or Works Cited page, by: Author's last name.
