The Chicago Manual of Style (CMS) is used for academic papers written primarily in the fields of history and social science. There are two forms of Chicago style: notes-bibliography (used in literature, history, and the arts) and author-date (used in social sciences). Ask your professor which form is needed.
Please note that citation styles encompass not only how sources are cited but also how the paper is formatted.
Please note that while citation creators can be helpful and time-saving, they are nevertheless unreliable: Check your citations for correct formatting with one of the Chicago citation guides listed above.
