Q. How do I cite a law review article that doesn't list the author?
This "note" in the Harvard Law Review is student-written and anonymous. In the journal's "about" page online, they state in the second to last paragraph that "All student writing is unsigned."
As for citing that note, you'll want to look at Bluebook rule 16.7.1(b) dealing with unsigned, student-written materials. We have copies of the Bluebook on reserve if you need to borrow a copy.
