Banned Books Week is an annual event celebrating the freedom to read. Typically held during the last week of September, it highlights 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.

Who Bans or Challenges Books?
First, it's important to emphasize that neither librarians nor libraries ban or challenge books! Libraries are all about the freedom to read and librarians discourage censorship in all forms. Typically, a book challenge or banning occurs when individual or group decides that a particular book does not belong on the shelf in a library because of something that particular individual or group does not like about the book. Perhaps they think it uses offensive language or presents an idea that is radical or different from societal norms. Perhaps these individuals believe they need to protect children or another group from non-mainstream, difficult or controversial ideas and information. Parents challenge books more often than any other individual or group, but other examples are: government bodies, elected officials, religious organizations or officials, board members and even teachers!
Why are Books Banned or Challenged?
