Many things have changed since ALA's Office for Intellectual Freedom (OIF) was founded in 1967, but not everything: the most beloved and popular children's books are still among the most challenged, frequent targets of censorship and outright bans. Limiting access to controversial titles such as Captain Underpants, The Dirty Cowboy, Blubber, or Scary Stories to Tell in the Dark or leaving them out of a library's collection altogether is not the answer to challenges. In this important book, Scales gives librarians the information and guidance they need to defend challenged books with an informed response while ensuring access to young book lovers.
