Understanding Chicago Citation Style
Chicago citation style is a widely used system for academic writing, particularly in history, literature, and the arts. It offers two distinct systems: Notes-Bibliography (NB) and Author-Date (AD). Choosing the right system often depends on your field or the specific requirements of your instructor or publisher.
Notes-Bibliography (NB) System
The Notes-Bibliography system uses footnotes or endnotes to cite sources within the text. These notes provide detailed information about the source the first time it's cited, and subsequent citations of the same source are shortened. A bibliography at the end of the paper lists all sources cited. This system is common in humanities disciplines.
How to Use Footnotes/Endnotes
When you quote, paraphrase, or refer to an idea from a source, you insert a superscript number after the relevant text. This number corresponds to a note at the bottom of the page (footnote) or at the end of the document (endnote).
First Footnote/Endnote Citation:
Let's say you're citing a book by John Smith titled "The History of Chicago," published in 2020 by University of Chicago Press.
- Book:
John Smith, The History of Chicago (Chicago: University of Chicago Press, 2020), 45.
If the book has an editor, include their name:
- Book with Editor:
Jane Doe, ed., Collected Works of Emily Dickinson (Cambridge, MA: Harvard University Press, 2018), 112.
For a journal article:
- Journal Article:
Robert Johnson, "Urban Development in the Midwest," Journal of American History 75, no. 3 (2019): 210.
For a website:
- Website:
"About Chicago," City of Chicago Official Website, accessed October 26, 2023, https://www.chicago.gov/about.
Subsequent Footnote/Endnote Citation:
After the first full citation, subsequent references are shortened.
- Shortened Book Citation:
Smith, History of Chicago, 78.
- Shortened Journal Article Citation:
Johnson, "Urban Development," 215.
The Bibliography
The bibliography is an alphabetical list of all sources you've cited in your notes. The format is similar to the first note, but it doesn't include page numbers unless you're citing a specific range for the entire work.
- Book:
Smith, John. The History of Chicago. Chicago: University of Chicago Press, 2020.
- Book with Editor:
Doe, Jane, ed. Collected Works of Emily Dickinson. Cambridge, MA: Harvard University Press, 2018.
- Journal Article:
Johnson, Robert. "Urban Development in the Midwest." Journal of American History 75, no. 3 (2019): 205–22.
- Website:
"About Chicago." City of Chicago Official Website. Accessed October 26, 2023. https://www.chicago.gov/about.
Author-Date (AD) System
The Author-Date system uses in-text citations consisting of the author's last name and the publication year. A reference list at the end of the paper provides full details for each source. This system is more common in social sciences and some natural sciences.
In-Text Citations
When you cite a source in the text, you include the author's last name and the year of publication in parentheses.
- Paraphrasing:
(Smith 2020) or Smith (2020) argues that Chicago's growth was unprecedented.
- Direct Quote:
(Smith 2020, 45) or Smith states that "the city's expansion was a marvel" (2020, 45).
If a source has no author, use a shortened version of the title.
- No Author:
("About Chicago" 2023)
If you have multiple works by the same author in the same year, add a letter to the year:
- Multiple Works by Same Author:
(Smith 2020a) (Smith 2020b)
The Reference List
The reference list is an alphabetical list of all sources cited in your text. The format is similar to the bibliography in the NB system, but includes the publication year immediately after the author's name.
- Book:
Smith, John. 2020. The History of Chicago. Chicago: University of Chicago Press.
- Book with Editor:
Doe, Jane, ed. 2018. Collected Works of Emily Dickinson. Cambridge, MA: Harvard University Press.
- Journal Article:
Johnson, Robert. 2019. "Urban Development in the Midwest." Journal of American History 75, no. 3: 205–22.
- Website:
"About Chicago." 2023. City of Chicago Official Website. Accessed October 26, 2023. https://www.chicago.gov/about.
Common Chicago Style Elements
Regardless of which system you use, some elements are consistent:
- Titles of Books and Journals: Italicize.
- Titles of Articles and Chapters: Use quotation marks.
- Publication City: Always include. If the city is not well-known or could be confused with another, include the state abbreviation.
- Page Numbers: For direct quotes and specific references, include them. For general references, they might be omitted in the bibliography/reference list.
- Access Dates for Websites: Crucial, as web content can change.
When to Use Which System
- Notes-Bibliography: Primarily used in fields like history, literature, art history, and musicology. It's favored for its ability to provide detailed source information without interrupting the text flow as much as parenthetical citations might.
- Author-Date: Common in social sciences (sociology, political science, economics) and some natural sciences. It's often preferred for its conciseness within the text.
Tips for Effective Citation
- Be Consistent: Whichever system you choose, apply it uniformly throughout your paper.
- Consult the Manual: The official The Chicago Manual of Style is the definitive guide. For specific questions, refer to its latest edition.
- Check Requirements: Always confirm the citation style required by your instructor, professor, or publisher.
- Use Citation Tools Wisely: Tools can help, but always double-check their output against the style guide. If you're struggling to get your citations just right, EssayGazebo.com offers professional editing and formatting services to ensure accuracy and adherence to the Chicago style.
