I thought that it may or may not be a good idea to keep a history of what Disney Animated Classics were released when. I also thought it would be good to have a complete list of what has and has not been announced so far.

If the film has been rereleased as a Blu-ray/DVD combo pack, is on Blu-ray 3D, or if it is currently in the Disney Vault, it will be noted on the side.
