The Chicago Notes-Bibliography system that you are encouraged to use is a system for referencing sources through footnote citations in your writing and through bibliography pages at the end of your paper.
You should include a footnote each time you use a source, whether it is a direct quote or a paraphrase/summary. Footnotes will be added at the end of the page on which the source is referenced.
The bibliography at the end of your paper is an alphabetical list of all sources you have used. All sources (books, articles, Web sites, etc.) are arranged alphabetically by author’s last name. If no author or editor is listed, the title or keyword by which someone would search for the source can be used.
