Chicago Format Style covers citation format for history, physical, natural and social sciences. It is published by the University of Chicago Press. The Chicago Manual of Style (CMOS), 17th edition is over a thousand pages, including its bibliography. Fortunately, there is a shorter, student version of CMOS available. This student version is often called Turabian style after the author of A Manual for Writers, Kate L. Turabian.
Chicago or CMOS consists of two different styles. One style is an author-date style, which is simple to use. The author-date style is used in physical, natural and social sciences. Students will use the author-date style for school projects, in most cases.
The second style is notes-biblio style. Notes-biblio is an extensive notes bibliographic style. Notes can be formatted as endnotes or footnotes. Chicago/Turabian is used for history, literature and the arts. Note numbers are placed within the text, then information about the source is placed at the end of the chapter or at the bottom of the page. Each note is cited within a bibliography at the end of the paper.
