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.
