In history and some humanities courses, you may be asked to use the documentation system of The Chicago Manual of Style, 17th ed. (Chicago: University of Chicago Press, 2017).
In Chicago style, the text of the paper contains raised arabic numerals that correspond to numbered notes at the foot of the page or at the end of the paper. When you use Chicago-style notes, you will usually be asked to include a bibliography as well. A bibliography, which appears at the end of your paper, gives publication information for every work you have cited in your notes.
