The Chicago manual of style includes two systems of citation: the Notes and Bibliography system and the Author/Date system. Both serve the same purpose of citing the sources referenced within an academic/professional text, but through different means. Though both are equally valid methods of citing your sources, the Notes and Bibliography system is the most commonly used within Chicago style. Known also as "the footnote style," the Notes and Bibliography style is the one most professors mean when they ask for a paper to be written using Chicago style.
If your professor is not specific about which Chicago citation system they prefer, do not assume that this means you can choose between the two. If they do not clarify, they are most likely referring to the Notes and Bibliography system, as that is far and away the most common version to use. But as with all things academia: When in doubt, Ask!
The Notes and Bibliography System is the most widely known and used version of citing sources in Chicago style. This is the preferred system within Chicago system for most professors at the University of Mary.

The Author/Date system of Chicago style is a unique system of citation and formatting that is largely recognized by its in-text, parenthetical citations (visually, it is very similar to MLA style). Typically, this system is not used much at the University of Mary, so check with your professors before using it in any class.
