Citing Others' Work

Notes & Bibliography in Chicago Style

Chicago style follows a "notes and bibliography" format. This means that unlike MLA and APA styles, which use parenthetical in-text citations, Chicago style makes heavy use of footnotes (see example page below). There are slight differences in punctuation and format between note citations occurring throughout a document (indicated in this guide's examples by N:) and bibliography citations occurring at the end of the document (indicated in this guide's examples by B:).
