Hi, I'm new, I just joined the forums

I read a great article on here by Samland I was wondering if anyone knows where I can find more information about the Disney Hyperion studios or any articles/websites/blogs/documentaries/threads/etc. about the history of Disney and how the company started?

Here are some of the sources I already have (Haven't fully explored them yet though):

2719 HYPERION
Michale Barrier and Neal Gabler's recent biographies of Walt Disney
Pierre Lambert's Blanche Neige
Leonard Maltin's Of Mice and Magic
Enchanted Drawings: The history of Animation.

Thanks so much!
