A year later in 1977 it was removed from high school classrooms in Westport, Massachusetts over similar concerns with "objectionable" language. In 1982, it was removed from two Anniston, Alabama libraries, later to be reinstated on a restricted basis. Also, in 1973 a bookseller was arrested for selling the novel. The charges were later dropped.
