Don’t join the book burners. Don’t think you’re going to conceal faults by concealing evidence that they ever existed. Don’t be afraid to go in your library and read every book.
― Dwight D. Eisenhower
A banned book is a book that may be:
The most extreme form of banning is the death or demand for the death of the author, as has happened in the case of Salman Rushdie.
A challenge is an attempt to remove or restrict materials based upon the objections of a person or a group thereby restricting the access of others.
A banning is the removal of those materials that have been challenged and that challenge has succeeded.
