What if I am citing the same source two or more times in a row using the Chicago Manual of Style/Turabian?
Answer
Here's how shortened citations work in Chicago Manual of Style.
In the 17th edition of the Chicago Manual of Style (also known as Turabian), the first time you cite a source in the text, the corresponding note (footnote or endnote) should be a full note citation.
For example:
Full footnote/endnote citation:
1 Robert G. Wick, “‘He Was a Friend of Us Poor Men’: Ida M. Tarbell and Abraham Lincoln’s View of Democracy,” Indiana Magazine of History 114, no. 4 (December 2018): 255, https://doi.org/10.2979/indimagahist.114.4.01.
2 George Herbert, Scientists for the Ethical Treatment of Lab Animals in the United States (New York: Putnam, 2004), 303.
Any subsequent citations for that source can be shortened versions. This should include the author’s last name, a shortened version of the title (if longer than 4 words), and page numbers (or other directing information). For example:
Shortened Footnote/Endnote:
3 Wick,"Poor Men," 256.
4 Herbert, Ethical Treatment, 304.
If you immediately cite the same source again, you can omit the title. For example:
5 Herbert, 305
The page number cannot be omitted if you cite the same page again. For example:
6 Herbert, 305
If you switch back to another source you have already cited in full, you use the shortened version with the title.
For example:
7 Wick,"Poor Men," 256.
Note: Previous editions of the Chicago Manual of Style allowed for the use of Ibid. (Latin for Ibidem, "in the same place") when citing a source multiple times in a row. The use of shortened citations is now preferred over the use of Ibid.
