Chicago Style

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.
