This document provides a brief history of banned and challenged books from ancient times to the present. It discusses how censorship of written works began as a means of political control but shifted to a focus on morality during the Victorian era in England. The passage of the Comstock Act in 1873 in the United States led to censorship of any literature or art deemed obscene, including birth control information. Court cases in the 1960s tested American laws on pornography and helped establish that books like Henry Miller's Tropic of Cancer were not legally obscene. Libraries continue to face challenges to books but promote freedom of expression and access to information.
