Most databases have a Cite Thisbutton (it may just look like a double quote: ") that will generate a citation for you. For History papers, select Chicago when asked to choose a citation style. It's always a good idea to double check the formatting of a generated citation. The guides below provide useful examples to follow.
The following pages will have sample bibliographic entries using Chicago style. Each example will have three entries. The first entry shown is the first note for a source. The second entry shown is for subsequent notes for a source. The third entry is the bibliographic entry for the note. This will be found in the bibliography at the end of the work.
ZoteroBib helps you build a bibliography instantly from any computer or device, without creating an account or installing any software. If you need to reuse sources across multiple projects or build a shared research library, we recommend using Zotero instead.
