Frequently challenged books of the 21st century

Each year, the ALA's Office for Intellectual Freedom compiles a list of the top ten most frequently challenged books. 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 2001 to 2008

Over the past eight years, American libraries were faced with 3,736 challenges.

  • 1,225 challenges due to “sexually explicit” material;
  • 1,008 challenges due to “offensive language”;
  • 720 challenges due to material deemed “unsuited to age group”;
  • 458 challenges due to “violence”
  • 269 challenges due to “homosexuality”; and

Further, 103 materials were challenged because they were “anti-family,” and an additional 233 were challenged because of their “religious viewpoints.”

1,176 of these challenges (approximately 31%) were in classrooms; 37% were in school libraries; 24% (or 909) took place in public libraries.  There were less than 75 challenges to college classes; and only 36 to academic libraries.  There are isolated cases of challenges to materials made available in or by prisons, special libraries, community groups, and student groups.  The majority of challenges were initiated by parents (almost exactly 51%), while patrons and administrators followed behind (10% and 8% respectively).
