Q. Which comes first in a bibliography, edition number or editor? What would the sequence be if there is an author, an editor, an edition number, and a specific page range of the chapter one is citing?
A. List the edition followed by the editor, according to the following pattern:
Surname, First Name. “Chapter Title.” In Book Title, 3rd ed., edited by First Name Surname, 26–42. City: Publisher, 2020.
It’s important to list the edition immediately after the title of the book, because in some cases a subsequent edition will have been edited by someone other than the editor(s) of previous editions. Few books fit this pattern neatly, but you can adapt the entry as needed. For example, here’s how you would cite a chapter in the 2019 paperback version of a 2008 second edition of a collection of novels edited by B. P. Reardon and published by the University of California Press:
Xenophon of Ephesus. An Ephesian Tale. Translated by Graham Anderson. In Collected Ancient Greek Novels, 2nd ed., edited by B. P. Reardon, 145–97. Oakland: University of California Press, 2019.
The title of the chapter is in italics in this case because the chapter reproduces a novel—though a short one (see CMOS 8.178). For citing authors like Xenophon of Ephesus who are known primarily by a given name, see CMOS 14.83.
