I easily found a podcast about challenged books on youtube.com. This podcast is titled ZORN_Banned Books Final and I am assuming it was created for an assignment at the State University of NY Brockport. The author gives a brief history about challenged and banned books as well as book burnings. Her video has a mock courtroom with some internationally known titles such as Catcher In the Rye, James and the Giant Peach and Diary of a Young Girl, taking the stand in a court of law. Her parody of a book being on trial is humorous and it's surprising to see so many popular books were challenged at one point.
She then discusses in short;
Who can challenge a book?
What happens to the challenged book?
Why are books challenged?
The author feels that challenged and banned books is a form of censorship and everyone has the right to have access to all information, read all materials and the right to express opinions no matter how unpopular. She also give us some interesting facts such as between the years 1990 and 2000, 6,364 books were challenged.
