Censorship
"Censorship is the suppression of ideas and information that certain persons-individuals, groups, or government officials - find objectionable or dangerous. Censors pressure public institutions, like libraries, to suppress and remove from public access information they judge inappropriate or dangerous, so that no one else has the chance to read or view the material and make up their own minds about it. The censor wnats to prejudge materials for everyone." - ALA Banned Books Week
