Chicago Style 17th Edition

There are two Chicago citation styles:

  • Notes and Bibliography
  • Author-Date

Notes and Bibliography is used mostly in the humanities. Sources are cited in numbered footnotes or endnotes. Each citation corresponds to a superscript number in the text. The notes and bibliography style is more flexible than the author-date style.

Author-Date is used in the sciences and social sciences. In this style, the sources are cited in the text using the author name and the year of publication with a corresponding citation in the bibliography.
