A quick guide to Chicago-style citations

About Chicago Style

This guide is a general overview of how to cite common types of sources using the two versions of Chicago style for student writing.

The Chicago Manual of Style consists of two basic documentation styles:

Notes-Bibliography (NB) is common in art history, theology, history, and other humanities disciplines

NB format uses footnotes and endnotes with a bibliography at the end of the document to record sources

Author-Date (AD) is sometimes used in the social sciences

In the Author-Date system, sources are cited in the text, usually in parentheses, by author's last name and date of publication and expanded upon in a list of references at the end of the document, where full bibliographic information is provided.
