Im National Geographic gibt es unter dem Titel “The history of book bans—and their changing targets—in the U.S.” einen Beitrag zur Geschichte der Book Bans in den US-amerikanischen Schulbibliotheken:
“Even as social mores relaxed in the 20th century, school libraries remained sites of contentious battles about what kind of information should be available to children in an age of social progress and the modernization of American society. Parents and administrators grappled over both fiction and nonfiction during school board and library commission meetings.”
