"A challenge is an attempt to remove or restrict materials, based upon the
objections of a person or group. A banning is the removal of those
materials. Challenges do not simply involve a person expressing a point of
view; rather, they are an attempt to remove material from the curriculum or
library, thereby restricting the access of others." (Definition from ALA.)
