Have the Oz books ever been banned, edited, or censored?
Sadly, yes. There have been several recent attempts to remove The Wizard of Oz from school libraries or reading lists. None have been successful, so far as I’ve been able to discover, although some school students in Tennessee and Louisiana have been excused from reading the book on religious grounds. Some reasons critics have given, for example, is that the book depicts good witches, which they claim is theologically impossible, and that animals are elevated to the same level as humans. And as stated in the previous question, some public libraries used to not carry the Oz books for various reasons. While The Wizard of Oz couldn’t be found on the shelves of the Chicago library system as early as 1928, two of the most notorious incidents took place in the 1950s, when Senator Joseph McCarthy and the House Un-American Activities Committee were active and saw Communism in all aspects of life. Many libraries removed a number of books, including the Oz books, for being too “radical.” Fantasy
