Q. Bibliographical citations of books with more than two editors look weird to me. The following citation, at a glance, appears to have four editors, as there are four items separated by commas: Cypess, Rebecca, Beth L. Glixon, and Nathan Link, editors. Word, Image, and Song, Volume 1: Essays on Early Modern Italy. Rochester: University of Rochester Press, 2013. Is there a way to improve this citation and make it clear that there are three editors, Rebecca Cypess being just one person?
A. Yes, there is (aside from using semicolons, which we would not recommend; source citations are complicated enough as it is). Simply change the word order (and note that Chicago treats a volume number separately from the title; see CMOS 14.119):
Rebecca Cypess, Beth L. Glixon, and Nathan Link, eds. Word, Image, and Song. Vol. 1, Essays on Early Modern Italy. Rochester, NY: University of Rochester Press, 2013.
There: it no longer looks like a book by four editors, the first two of whom happen to be mononymous. But if you plan to include the citation in an alphabetical list, change it back to how it was; otherwise, the reason for doing this will become evident when you get to the letter R (at which point inverted names should start to seem normal).
