List of most commonly challenged books in the United States

From Wikipedia, the free encyclopedia

This is an old revision of this page, as edited by 2600:1700:7e31:5710:b95a:88d:4cf7:9c9d (talk) at 20:51, 17 June 2020. The present address (URL) is a permanent link to this revision, which may differ significantly from the current revision.

Judy Blume is the author featured most frequently on this list (five times). Her young adult novels are typically about coming of age issues such as teenage sexuality.
The Harry Potter series by J. K. Rowling was the most challenged work from 2000 to 2009. Its topics relating to things such as witchcraft have generated controversy.
The second oldest works featured on the list were written by Mark Twain. Adventures of Huckleberry Finn (1884) is challenged consistently for its language and discussion of racism.

This list of the most commonly challenged books in the United States refers to books sought to be removed or otherwise restricted from public access, typically from a library or a school curriculum. This list is primarily based on U.S. data gathered by the American Library Association's Office for Intellectual Freedom (OIF), which gathers data from media reports, and from reports from librarians and teachers.[1]

According to the OIF, the top three reasons for challenging such materials were that they contained "sexually explicit" content, "offensive" language, or were "unsuited to age group".[2][3]

List

The list is sorted alphabetically by default. Included is each book's rank in the ALA's lists of top 100 challenged books by decade (if applicable).
