The growing amount of activity by pressure groups, as well as professional statements like those of the American Library Association and the American Association of Library Teachers, reflect an increased concern with legal, quasi-legal or extra-legal censorship. The National Organization for Decent Literature, a Catholic-Church sponsored censorship group, publishes an evaluation of materials, and while they do not intend their lists for boycott or coercion, they admit that that has occurred. The activities of Citizens for Decent Literature (now the most active and successful of the "decency movement" groups) parallel those of the New Jersey Committee for the Right to Read and the National Council for Freedom to Read. Each of these groups has (1) attempted to influence the public through speakers and newsletters, (2) provided some legal assistance, and (3) surveyed psychiatrists as to the effects of pornography, particularly on the young. Of these two forces, the activities of the "decency movement" have enjoyed broader, more vocal public support. (Examples of court decisions and local news concerning censorship are cited throughout the report.) (MF)
