Alphabetizing

Q. Would I alphabetize Kimberly Bowen-Smith Rinehart under B or under R?

A. We assume that the surname is the last word or hyphenated words in a name. Thus Kimberly Bowen-Smith Rinehart would go under R; Kimberly Rinehart Bowen-Smith would go under B; and Kimberly Bowen Smith would go under S.
