Turbian Style

The Chicago Manual of Style, 17th ed., is used by some fields in the humanities, mainly history and some sciences. The Turabian style is a shortened version of Chicago.

The Chicago style has two different techniques for formatting citations: Notes-Bibliography (N/B) and Author-Date (A/D).

Notes-Bibliography is usually used in history, arts, and humanities. This format uses a superscript numeral in the text after the item cited, and then either a footnote at the end of the page or an endnote at the end of the essay. These end/footnotes contain full bibliographic information about the source. This format requires a complete Bibliography at the end of the paper.

Author-Date is usually used for the social sciences and sciences. This format uses an in-text parenthetical author-date method. Papers using this method will include Reference List.

Be sure to check with your professor as to which method to use.
