If you are using Chicago style footnotes or endnotes, you should include a bibliography at the end of your paper that provides complete citation information for all of the sources you cite in your paper. Bibliography entries are formatted differently from notes. For bibliography entries, you list the sources alphabetically by last name, so you will list the last name of the author or creator first in each entry. You should single-space within a bibliography entry and double-space between them. When an entry goes longer than one line, use a hanging indent of .5 inches for subsequent lines. Here’s a link to a sample bibliography that shows layout and spacing. You can find a sample of note format here.
Examples
Complete note vs. shortened note
Here’s an example of a complete note and a shortened version of a note for a book:
1. Karen Ho, Liquidated: An Ethnography of Wall Street (Durham: Duke University Press, 2009), 27-35.
1. Karen Ho, Liquidated, 27-35.
Note vs. Bibliography entry
The bibliography entry that corresponds with each note is very similar to the longer version of the note, except that the author’s last and first name are reversed in the bibliography entry. To see differences between note and bibliography entries for different types of sources, check this section of the Chicago Manual of Style.
For Liquidated, the bibliography entry would look like this:
Ho, Karen, Liquidated: An Ethnography of Wall Street. Durham: Duke University Press, 2009.
Citing a source with two or three authors
If you are citing a source with two or three authors, list their names in your note in the order they appear in the original source. In the bibliography, invert only the name of the first author and use “and” before the last named author.
Note:
1. Melissa Borja and Jacob Gibson, “Internationalism with Evangelical Characteristics: The Case of Evangelical Responses to Southeast Asian Refugees,” The Review of Faith & International Affairs 17, no. 3 (2019): 80-81, https://doi.org/10.1080/15570274.2019.1643983.
Shortened note:
1. Borja and Gibson, “Internationalism with Evangelical Characteristics,” 80-81.
Bibliography:
Borja, Melissa, and Jacob Gibson. “Internationalism with Evangelical Characteristics: The Case of Evangelical Responses to Southeast Asian Refugees.” The Review of Faith & International Affairs 17. no. 3 (2019): 80–93. https://doi.org/10.1080/15570274.2019.1643983.
Citing a source with more than three authors
If you are citing a source with more than three authors, include all of them in the bibliography, but only include the first one in the note, followed by et al. (et al. is the shortened form of the Latin et alia, which means “and others”).
Note:
1. Justine M. Nagurney, et al., “Risk Factors for Disability After Emergency Department Discharge in Older Adults,” Academic Emergency Medicine 27, no. 12 (2020): 1271.
Short version of note:

Citing a book consulted online
If you are citing a book you consulted online, you should include a URL, DOI, or the name of the database where you found the book.
Note:
1. Karen Ho, Liquidated: An Ethnography of Wall Street (Durham: Duke University Press, 2009), 27-35, https://doi-org.ezp-prod1.hul.harvard.edu/10.1215/9780822391371.
Bibliography entry:
Ho, Karen. Liquidated: An Ethnography of Wall Street. Durham: Duke University Press, 2009. https://doi-org.ezp-prod1.hul.harvard.edu/10.1215/9780822391371.
Citing an e-book consulted outside of a database
If you are citing an e-book that you accessed outside of a database, you should indicate the format. If you read the book in a format without fixed page numbers (like Kindle, for example), you should not include the page numbers that you saw as you read. Instead, include chapter or section numbers, if possible.
Note:
1. Karen Ho, Liquidated: An Ethnography of Wall Street (Durham: Duke University Press, 2009), chap. 2, Kindle.
