I picked up The Vault of Walt - Unofficial, Unauthorized, Uncensored Disney Stories Never Told (paperback; 478 pages) written by Jim Korkis (or more commonly known by his pen name on MousePlanet; Wade Sampson).
Jim strings together many stories about Walt Disney by placing them within four different sections of the books: Walt, The Films, The Parks and Miscellaneous. The stories are rather short and the themes are very familiar, but Jim is able to flesh out details and expand on topics that other authors have probably ignored.
It's a fun read. And, each story is self-contained. You can read the book from beginning to end, or hop around.
