When several researchers share the same name, it's hard to tell whose publications are whose, says Nature News' Declan Butler. In 2011, Y. Wang was credited as an author on 3,926 publications — that's more than 10 per day — though, of course, the publications were written by many different people with the same name. "The list of the world's top 100 authors, all of whom show similarly impressive production rates, is a who's who of conflated Zhangs, Lis, Chens, Lees and other Wangs," Butler says.
