L. Frank Baum Tells How To Read the Wizard of Oz “Such a appreciation as yours is my greatest reward in writing stories for children,” he writes. “I want to amuse the little ones and at the same time strengthen their imaginations, as I believe the future development of civilization depends on the imagination of coming generations more than anything else. I also try to insert a covert moral, which the child may not discover but will nevertheless sense, and to keep the little stories as pure and sweet as they are adventurous.. The Oz books need not be read consecutively, but still if you read them in the order in which they were written you will understand the characters better. The Wizard of Oz; The Land of Oz; Ozma of Oz; Dorothy and the Wizard in Oz; The Road to Oz; The Emerald City of Oz; Tik-Tok of Oz; the Scarecrow of Oz. Also I wish you would read The Sea Fairies and Sky Island, which, while not Oz books, are among my best. I also like John Dough and the Cherub, the story of the Gingerbread Man.”
Appeals Court To Determine If Wizard Of Oz Images Can Be Retroactively Plucked Out Of The Public Domain Patently-O has an interesting discussion about an appeal being heard in the 8th Circuit, involving a question of the boundaries of copyright and the public domain in some images from public domain movie posters for The Wizard of Oz, Gone With The Wind and various Tom and Jerry cartoon films. Of course, back when these came out, in and around 1939, you had to specifically register works to have them covered by copyright. Not surprisingly, the works themselves were registered. However, some of the publicity posters that were used to promote them were released prior to the films being copyrighted (and were not copyrighted themselves) and, thus, are considered public domain.
