Some challenges resulted in the removal of the book from libraries, or in parental permission being required for a student to check the book out of a library. According to "The New York Times", in the 1970s it became common practice for school libraries to keep "Go Ask Alice" off library shelves and make it available to students only upon request, a practice which was criticized as being a form of censorship. A 1982 survey of school librarians across the United States, co-sponsored by the National Council of Teachers of English, found that "Go Ask Alice" was the most frequently censored book in high school libraries.
