Chicago style citation follows the rules outlined in the Chicago Manual of Style.  These rules tell you how to refer to information sources within the text of your paper, and also how to cite your sources in the bibliography at the end.  Chicago style is most often used by writers and editors of scholarly books and journals.  Depending on the discipline, there are two systems that can be used to cite things in the Chicago style.  Those in the disciplines of literature, history, and the arts often prefer the notes and bibliography system.  Those in the disciplines of physical, natural and social sciences usually prefer the author-date system.  If you aren't sure which to use, check with your professor.
