A study designed to provide a systematic description of the incidence of censorship and the censorship incidents reported by a selected group of teachers during a specified time period is presented. Objectives are: (1) to provide some measure of the frequency of censorship incidents experienced by a sample population of teachers of English, and (2) to describe the incidents. Censorship is defined as the withholding of a cmmunication from one person to another. This study focuses on that form of censorship which proscribes or restricts the use of specific books in the public secondary school English curriculum. The censorship pressures to be described are those put upon the teacher of English as he considers, recommends, selects, or uses works of literature and other pertinent books in his professional capacity. Conclusions include: (1) English teachers who were the object of censorship pressures were objects because they were doing a good job of teaching English; (2) Those teachers who reported censorship experience often were ones who used practices which supposedly help to prevent censorship attempts; (3) In half of the instances reported, the would-be censors were parents; and (4) The major burden of defense against censorship must be carried by the teacher.
