Citation, Documentation of Sources
Q. In a book compiling chapters written by multiple authors, if I want to cite a chapter written by one or more authors who are also editors of the whole book, do I have to repeat their names?
A. Yes, you should repeat their names. For example, the following bibliography entry will make it clear that Gordon H. Chang is both the sole author of the chapter and one of the editors of the book.
Chang, Gordon H. “Chinese Railroad Workers and the US Transcontinental Railroad in Global Perspective.” In The Chinese and the Iron Road: Building the Transcontinental Railroad, edited by Gordon H. Chang and Shelley Fisher Fishkin, with Hilton Obenzinger and Roland Hsu, 27–41. Stanford, CA: Stanford University Press, 2019.
You might avoid repetition by using only the surname on second mention of a contributor (“edited by Chang and Shelley Fisher Fishkin”), but only if space is an issue. The additional contributors Obenzinger and Hsu appear on the title page; listing them is optional (see CMOS 14.105).
