Banned Books Week is an annual event celebrating the freedom to read. Highlighting the value of free and open access to information. 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.

A challenge is an attempt to remove or restrict access to materials or services based upon the objections of a person or group.
A book is banned when it is entirely removed from a collection in response to a formal or informal challenge.
