Banned Books Week is an annual event celebrating the freedom to read. Banned Books Week was launched in 1982 in response to a sudden surge in the number of challenges to books in schools, bookstores and libraries.
Banned Books Week brings together the entire book community — librarians, booksellers, publishers, journalists, teachers, and readers of all types — in shared support of the freedom to seek and to express ideas, even those some consider unorthodox or unpopular.
By focusing on efforts across the country to remove or restrict access to books, Banned Books Week draws national attention to the harms of censorship. The ALA (OIF) compiles as reported in the media and submitted by librarians and teachers across the country.
The ALA Office for Intellectual Freedom tracked 156 challenges to library, school, and university materials and services in 2020. Of the 273 books that were targeted, here are the most challenged, along with the reasons cited for censoring the books:
