Thirty years ago, there was a surge in books being banned from schools, bookstores, and libraries. To call attention to this issue and celebrate the freedom to read, the national book community launched Banned Book Week in 1982. As a part of this movement, the American Library Association's office of Intellectual Freedom compiles reports each year of the most challenged books.
Challenged books are ones that people have continually sought to ban from libraries and schools across the country. Stories are challenged for a number of reasons, but the most common motivation is to protect children from material considered inappropriate by some adults.
