As you may have heard, this week is
Banned Books Week, an annual event celebrating the freedom to read. It's about celebrating the books that have been challenged, restricted and outright forbidden in some parts of the world.
According to the American Library Association, more than 11,300 books have been challenged since 1982. A challenge is an attempt to ban or restrict materials based upon the objections of a person or group. When books are banned, they are removed from libraries and schools and people's access to them is restricted, so it's a type of censorship. Books have been challenged or banned for all sorts of reasons, including their sexual or violent content and religious or political messages.
