Chicago Manual of Style (16th Ed.) - Most recent is 17th Ed.

Chicago Manual of Style is most commonly used to write papers and cite sources within the humanities (social studies/history).
"The Chicago Manual of Style (CMS) covers a variety of topics from manuscript preparation and publication to grammar, usage, and documentation and has been lovingly called the 'editors’ bible.' The material in this resource focuses primarily on one of the two CMS documentation styles: the Notes-Bibliography System (NB), which is used by those in literature, history, and the arts. The other documentation style, the Author-Date System, is nearly identical in content but slightly different in form and is preferred in the social/sciences."(1)

Note: In the 17th Edition, the use of "Ibid" is now discouraged in favor of using shortened citations

If you consecutively cite the same source two or more times in a note (complete or shortened), you may use the word “Ibid” instead. Ibid is short for the Latin ibidem, which means “in the same place”. If you’re referencing the same source but different page, follow ‘Ibid’ with a comma and the new page number(s).
