The Chicago style has two documentation systems:
Notes-Bibliography - Preferred by scholars in the humanities (arts, literature, history, etc.).
Place citations in notes either at the end of the page (footnotes) or at the end of the paper (endnotes). List all sources at the end of your paper on a new page entitled "Bibliography." Alphabetize the bibliography by author's last name, or by title if a work's author is unknown.
Author-Date - More concise; usually used by scholars in the sciences and social sciences.
Provide brief parenthetical citations within the paper (usually the author's last name and publication date). List full citations at the end of the work in a "Reference List."
The examples follow the notes-bibliography style. Chapters 16 and 17 of the manual provide full details on both formats.
