Each year, the ALA's Office for Intellectual Freedom compiles a list of the top ten most frequently challenged books in order to inform the public about censorship in libraries and schools. The ALA condemns censorship and works to ensure free access to information.
A challenge is defined as a formal, written complaint, filed with a library or school requesting that materials be removed because of content or appropriateness. The number of challenges reflects only incidents reported. We estimate that for every reported challenge, four or five remain unreported. Therefore, we do not claim comprehensiveness in recording challenges.
Background Information from 2000 to 2009
Over this recent past decade, 5,099* challenges were reported to the Office for Intellectual Freedom.
Further, 274 materials were challenged due to "occult" or "Satanic" themes, an additional 291 were challenged due to their "religious viewpoint," and 119 because they were "anti-family."
Please note that the number of challenges and the number of reasons for those challenges do not match, because works are often challenged on more than one ground.
1,639 of these challenges were in school libraries; 1,811 were in classrooms; 1,217 took place in public libraries. There were 114 challenges to materials used in college classes; and 30 to academic libraries. There are isolated cases of challenges to library materials made available in or by prisons, special libraries, community groups, and students. The vast majority of challenges were initiated by parents (2,535), with patrons and administrators to follow (516 and 489 respectively).
*We receive challenge reports after the top ten list has been published. This number reflects all the challenges we received since July 31, 2013 for the 2000-2009 time period.
