In 1960, a teacher in Tulsa, Oklahoma was fired for assigning the novel in class; however, he was later reinstated. Between 1961 and 1982, The Catcher in the Rye was the most censored book in high schools and libraries in the United States. The book was banned in the Issaquah, Washington, high schools in 1978 as being part of an "overall communist plot". In 1981, it was both the most censored book and the second most taught book in public schools in the United States. According to the American Library Association, The Catcher in the Rye was the 10th most frequently challenged book from 1990 to 1999. It was one of the ten most challenged books of 2005, and although it had been off the list for three years, it reappeared in the list of most challenged books of 2009.
The challenges generally begin with Holden's frequent use of vulgar language, with other reasons including sexual references, blasphemy, undermining of family values and moral codes, encouragement of rebellion, and promotion of drinking, smoking, lying, and promiscuity. Often the challengers have been unfamiliar with the plot itself. Shelley Keller-Gage, a high school teacher who faced objections after assigning the novel in her class, noted that "the challengers are being just like Holden... They are trying to be catchers in the rye". A reverse effect has been that this incident caused people to put themselves on the waiting list to borrow the novel, when there were none before.
