Censorship is the suppression of ideas and information that certain persons — individuals, groups, or government officials — find objectionable or dangerous. It is no more complicated than someone saying, “Don’t let anyone read this book, or buy that magazine, or view that film, because I object to it!” Censors try to use the power of the state to impose their view of what is truthful and appropriate, or offensive and objectionable, on everyone else. Censors pressure public institutions, like libraries, to suppress and remove information they judge inappropriate or dangerous from public access, so that no one else has the chance to read or view the material and make up their own minds about it. The censor wants to prejudge materials for everyone.
“Libraries should challenge censorship in the fulfillment of their responsibility to provide information and enlightenment.”— Article 3, Library Bill of Rights
“Congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof; or abridging the freedom of speech, or of the press; or the right of the people peaceably to assemble, and to petition the Government for a redress of grievances.” First Amendment of the U.S. Constitution passed by Congress September 25, 1789. Ratified December 15, 1791.
