Chicago-Style Citation Quick Guide




CHAPTER 13- Source Citations: Overview

Chicago style offers two source formatting options: Notes and bibliography and Author-date.

13.18: Notes and bibliography In this system, sources are cited in numbered footnotes or endnotes. Each note corresponds to a raised (superscript) number in the text. Sources are also usually listed in a separate bibliography. The notes and bibliography system can accommodate a wide variety of sources, including unusual ones that don’t fit neatly into the author-date system.

13.102: Author-date system In this system, sources are briefly cited in the text, usually in parentheses, by author’s last name and year of publication. Each in-text citation matches up with an entry in a reference list, where full bibliographic information is provided.

Citation Managers

Citation managers (also called reference managers) are tools you can use to:

  • Save and organize your references to books, articles, movies, and other sources information
  • Format bibliographies and works cited lists in multiple citation styles
  • Insert in-text citations into the body of a document
  • Share references with others
