Citations Guide

Citation Guide for APA, MLA, and Chicago Styles

Chicago: Overview

Welcome to Community College of Aurora's guide to the Chicago Manual of Style (17th edition) format! The contents of this guide include general information, guides for footnotes/endnotes, and bibliographies.  

How is Chicago different from APA and MLA?

In Chicago style, superscript numbers in the text of the paper refer readers to notes with corresponding numbers either at the foot of the page (footnotes) or at the end of the paper (endnotes). A bibliography is often required and appears at the end of the paper. The bibliography is in alphabetical order by author last name and gives publication information for works cited in the notes.

General Guidelines for a Chicago-Style Paper*

  • Font 12 point, Times New Roman
  • Double spaced (except for block quotes, notes, and citations)
  • 1" margins
  • Page numbers in upper right corner (excluding title page)
  • Title Page:
    • Papers title should be 1/3 of the way down the page in Bold 
    • Name, Class Information, and Date placed 2/3 of the way down the page

General Citation Guidelines

  • When indenting a citation make sure to note that a footnote/endnote is indented in the first line and the bibliography is indented in the second and subsequent lines.

  • After citing a source the first time, it is appropriate to use a shortened version of the citation when citing the same resource. The 17th edition discourages use of "Ibid."  

  • The shortened version of the reference starts with the author's last name and a shorter version of the title.  After the first shortened version, only the author's name and the page number are given. 
    • Note Example: 16. Steve Boyle, The Tortilla Curtain (London: Bloomsbury, 1995), 98.
    • Shortened Citation Example 1st version: 17. Boyle, Tortilla Curtain, 52-65.
    • Shortened Citation Example all subsequent versions: 18. Boyle 22. 
    • 19. Boyle 19.
    • 20. Boyle 12-20.

  • NOTE: To ensure you are following assignment guidelines, please check with your professor.

Sample Chicago Manual of Style Annotation

Davidson, Hilda Ellis. Roles of the Northern Goddess. London: Routledge, 1998.

     Davidson's book provides a thorough examination of the major roles filled by the numerous pagan goddesses of Northern Europe in everyday life, including their roles in hunting, agriculture, domestic arts like weaving, the household, and death. The author discusses relevant archaeological evidence, patterns of symbol and ritual, and previous research. The book includes a number of black and white photographs of relevant artifacts.

This annotation includes only one paragraph, a summary of the book. It provides a concise description of the project and the book's project and its major features.

Print Encyclopedia and Dictionary Entry

Major reference books are usually cited without any publication information and usually only in notes. Because most entries are small and do not have a specific author, you do not have to use an author name. For substantial entries such as "Egypt," it would be appropriate to cite the author like you would for a print book

Primary Sources

Primary Sources (especially those found in a museum or library) have different styles of citations based on what type of object it is (letter, Latin poem, papyrus, manuscript collections, etc.) Check the Chicago Manual of Style 17th edition or contact a librarian for the specific way to cite your primary source!

Primary Sources found in Secondary Sources

 

Footnote: Generally it is better to try and track down where the secondary source found the primary source that you want to use. If you can't find it, make sure to cite both the primary and the secondary source.

Example: Louis Zukofsky, " Sincerity and Objectification," Poetry 37 (February 1931): 269, quoted in Bonnie Costello, Marianne Moore: Imaginary Possessions (Cambridge, MA: Harvard University Press, 1981), 78.


Bibliography: Generally it is better to try and track down where the secondary source found the primary source that you want to use. If you can't find it, make sure to cite both the primary and the secondary source.

Example: Zukofsky, Louis. "Sincerity and Objectification." Poetry 37. February 1931: 269.  Quoted in Bonnie Costello, Marianne Moore: Imaginary Possessions. Cambridge, MA: Harvard University Press, 1981, 78. 

Personal Communication

Personal Communication are usually explained in the text of your paragraph or in a note. A bibliographic entry does not need to be created.

Footnote: Author First Name and Last Name, Communication Type, Date of Publication or Date When Communication Took Place.

Examples: 

1. Jane Doe, email message to author, August 17, 2020.

2. Snapchat sent to author, March 4, 2021.


Bibliography: Personal Communication does not need to be listed in the Bibliography.

According to the Chicago Manual of Style (CMS), citing AI within "most types of writing, you can simply acknowledge the AI tool in your text."  However, if writing a student or professional paper, AI should be cited more formally. 

Artificial Intelligence (AI)

Footnote: Author First and Last Name, "Title of Article," Title of Journal Volume #, no. Issue # (Date of Publication): Page #.

Example: 1. Text generated by ChatGPT, OpenAI, March 7, 2023, https://chat.openai.com/chat.

*If the prompt has not been provided in the text of the paper, it can be included in the footnote. 

Example: 1. ChatGPT, response to “Explain how to make pizza dough from common household ingredients,” OpenAI, March 7, 2023.

*If the AI-generated text was edited, say this clearly in the text or at the end of the note (e.g., “edited for style and content”).

"ChatGPT stands in as “author” of the content, and OpenAI (the company that developed ChatGPT) is the publisher or sponsor, followed by the date the text was generated. After that, the URL tells us where the ChatGPT tool may be found, but because readers can’t necessarily get to the cited content (see below), that URL isn’t an essential element of the citation." 


Bibliography: No Bibliographic entry is required unless you can provide a publicly available link to the exact AI response.  Generally, treat AI responses like Personal Communication (i.e., only use the note, not the bibliography).
