Q. In a collection of (some previously published) essays all by one writer, does one cite the author as the editor too? CMOS 14.104 and 14.106 seem to come close, but they don’t address this exact situation. In the source I’m working with, the title page does not credit the author as editor, but some of the essays were previously published. Thanks!
A. No, you wouldn’t cite the author as both author and editor of the book. For example, “The Girl in the Window” and Other True Tales (University of Chicago Press, 2023) is an anthology of stories written by Pulitzer Prize–winning journalist Lane DeGregory that were originally published in the Tampa Bay Times (formerly the St. Petersburg Times).
The title page credits DeGregory as author of the book and Beth Macy as author of a foreword. No other contributor is listed. So even though it was DeGregory herself who compiled, edited, and annotated the stories, you wouldn’t cite her as editor also.
Besides, the words “edited by” don’t have the power to tell the reader that some or all of the essays in a book were previously published. If that info is relevant, you can say so either in the text (as we’ve done near the beginning of this answer) or in a note. But for the citation itself, follow the title page.
