Within the Florida prison system, more than 20,000 books have been banned and designated as contraband. Books on the banned list include choices like Ron Stallworth’s Black Klansman, which was recently adapted into an Academy Award–winning film, as well as language learning books and various how-to guides centered around anything from the legal system to computer basics. A slew of books within the For Dummies franchise have also been banned for presenting an apparent threat to security or order.
