Books have been banned as long as there have been books and continue to be banned or challenged even today. 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 during the Inquisition, or more recently with Salman Rushdie.
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. As such, they are a threat to freedom of speech and choice.
Pensacola's Booker T. Washington High School made national headlines in 2014 when the school principal canceled the One School/One Book summer reading program because Cory Doctorow's Little Brother promotes the questioning of authority, lauds "hacker culture," and discusses sex and sexuality in passing. After unsuccessfully urging the school to reinstate the book, Doctrow and his publisher sent 200 complimentary copies of the book directly to students.
