What's the difference?

The Notes and Bibliography Style of Chicago Manual of Style utilizes numbered footnotes or endnotes when citing sources in-text.

The Author-Date Style briefly cites sources in-text, usually in parentheses, by author's last name and year of publication.

The end bibliographies for both styles are similar, but the Author-Date has the date listed further up in the reference.

Chicago Manual of Style Online (SU Only)

"The Chicago Manual of Style presents two basic documentation systems, the humanities style (notes and bibliography) and the author-date system. Choosing between the two often depends on subject matter and nature of sources cited, as each system is favored by different groups of scholars.

The humanities style is preferred by many in literature, history, and the arts. This style presents bibliographic information in notes and, often, a bibliography. It accommodates a variety of sources, including esoteric ones less appropriate to the author-date system.

The more concise author-date system had long been used by those in the physical, natural, and social sciences. In this system, sources are briefly cited in the text, usually in parentheses, by author's last name and date of publication. The short citations are amplified in a list of references, where full bibliographic information is provided."

Introduction to Chicago Citation Style

Citing Artificial Intelligence (AI)

The use of ChatGPT or other AI tools in assignments should be discussed with your instructor. As a general rule, if you are incorporating any information from an AI tool into your research assignments, you must cite the AI tool or the information that the tool is directing you to.

For more information about ChatGPT and AI, please visit the Libraries' Artificial Intelligence guide.

For faculty/instructors looking for further teaching support and development around ChatGPT and AI, contact CTLE at CTLE@syr.edu

For anyone with questions about ChatGPT / AI and academic integrity, contact CLASS at aio@syr.edu.

Turabian: Chicago Style for Students and Researchers

*Please check with your instructor to be sure if you are required to use Chicago Style or Turabian Style.*

The style presented in Kate Turabian's "Manual for Writers of Research Papers" is essentially the same as that presented by the Chicago Manual of Style. However, it has been modified slightly for use by student writers and researchers. Please see the Turabian Citation Quick Guide Page on the Chicago Manual of Style website for more information, including citation examples.
