"Little Bill" series makes the 2016 "Most Challenged" List.
Bill Cosby’s “Little Bill” children’s book series was among the 10 “most challenged” books in 2016, according to a list compiled by the American Library Association’s Office for Intellectual Freedom.
A book is “challenged” when someone, like a parent or other community member, complains and tries to get the book removed from a library or a school curriculum.
