Best book for in depth history
I have many books and DVD's about Disney World, but none of them go into enough depth.
I have both trivia books, one of the Imagineer books, several of the guides for trip planning, Walt-Man Behind the Myth DVD and Modern Marvels DVD about WDW. I have enjoyed all of them, but I want more...
I am looking for a book that gives detailed history from planning to construction to all the day to day tasks that it takes to run the parks. Also information and other tidbits you would learn on a behind the scenes tour or picking the brain of someone that had been employed there since it opened.
Can anyone recommend a book/books that may come close to having this much info?
Thanks in advance.
