Chicago style offers two variations. Researchers in the humanities typically use a notes-and-bibliography system, while researchers in sciences and social sciences typically use an author-date system. This page provides examples of in-text citations and bibliography citations for the notes-and-bibliography style commonly used in the humanities.
In the notes-and-bibliography system used in the humanities, citations within the text will be noted with a footnote, as pictured below, and a bibliography lists all of the references cited.
