 Originally written by Forrest Spaulding, director of the Des Moines Public Library, in 1938, the Library Bill of Rights was adopted by the American Library Association in 1939, and has been revised several times since.Its original adoption was introduced with the statement, "Today indications in many parts of the world point to growing intolerance, suppression of free speech, and censorship affecting the rights of minorities and individuals," a reference to the emergence of totalitarian states during that time.During the Cold War period, the Library Bill of Rights supported opponents of censorship of materials interpreted as communist propaganda.
