Key Chicago formatting rules
- Decide upfront: notes-bibliography (humanities) or author-date (sciences). Do not mix.
- Footnote 1 (first reference) is the long form; subsequent notes use a shortened form.
- Bibliography uses inverted name order; footnotes use natural order.
- Include place of publication for books; use "and" not "&" for two authors.
- For 4+ authors in the note, use "et al." but list all authors in the bibliography.

Chicago FAQ
Notes-bibliography is the default in the humanities (history, art, religion) and is what most instructors mean when they say "Chicago." Author-date is closer to APA and is used in some sciences and economics journals.
Turabian is essentially Chicago adapted for student papers — same rules, but presented for theses and class assignments rather than publication. Most universities consider them interchangeable.
For graded papers, usually yes. The footnotes cite specific sentences; the bibliography lists every source consulted. A few short papers may use notes-only, but always check your instructor's requirements.
