Chicago Manual of Style is the citation and writing style that is used most often in the soft social sciences, humanities, and some policy (philosophy, history, public policy, classics, and more). This style relies on endnotes or footnotes for in-text citations and is relied upon for providing the reader a large amount of context for each citation.
Chicago citations are split into three categories:
Each of these looks a little bit different! The first two are in-text citations that, in Chicago, are either footnotes or endnotes, depending on your preference.
The first time you cite an item it will have a long citation that almost looks like a bibliography entry! This is because Chicago is built to give the reader of your work the most amount of context possible when they come across a citation. All other times you cite that item you'll use a short citation that still has a fair amount of information.
At the end of your paper you'll have a full citation list, a bibliography!
