Chicago Style: Basics

Shortened Notes

---

In Chicago Style, subsequent citations are formatted as shortened notes:

• The basic structure of the first shortened citation consists of the author(s)’s last name(s), the title of the work (usually shortened if more than four words), and the page number(s).
• The 17^th edition of the Chicago Manual of Style discourages the use of Ibid. Instead, the CMOS recommends the use of further shortened citations that consist of the author(s)’ last name(s) and the page number(s).
• Your readers will need to be able to identify the correct works; therefore, if you are using multiple works by one author, you will have to differentiate between the works.
  • You can use an even shorter version of each title. In the book example below, if you had two or more sources by Tomblin, the further shortened version of the citation could be:
    • Tomblin, Civil War, 32.

Ibid.

---

The 17^th edition of the Chicago Manual of Style discourages the use of Ibid. Instead, the CMOS recommends the use of shortened citations (see the examples above). However, if your professor allows it, Ibid. is used:

• When you cite the same source directly after another. 
• It can be used by itself or with different page numbers.

Example:

10. Moura and Almodovar, “Political Economy,” 63.

11. Ibid.

12. Ibid., 62.

13. Tomblin, Civil War on the Mississippi, 50.

14. Ibid., 56-62.

15. Moura and Almodovar, “Political Economy,” 62-3.
