The Disappearance of Books: Censorship and the First Amendment. Aaron visits his local library and finds that his favorite books are missing. He asks the librarian and learns about censorship and the first amendment. Censorship is when a government or authority restricts certain ideas, opinions, or information from reaching the public. The first amendment is a law that protects freedom of speech, press, religion, and assembly. Aaron learns that book censorship has occurred throughout history, and that some books are removed from shelves due to their content or because they may offend certain groups. He also discovers that James and the Giant Peach is a beloved book that has been removed from some libraries due to censorship.
