"Playboy: The Complete Centerfolds"... lol. J/K
Actually, I just picked up "Wrestling Tough" by Mike Chapman last week. The book doesn't go into techniques, but rather gives accounts to the mindset and attitudes behind wrestlers (amature, collegiate an olympic), as well as other athletes. There is a lot of name-dropping, but it's also very motivating.
Another classic (but hard to find, especially as a hardcover) is "In the Corner: Great Boxing Trainers Talk About Their Art" written by Dave Anderson. It's a series of interviews with a lot of great trainers, such as Kevin Rooney, Angelo Dundee, Emmanuel Steward, etc. They talk about how they brought up a lot of their more well-known fighters, as well as what they thought made the heart of their fighters. Personally, I can't say enough about how good this book is. I actually considered lifting it from a local library (it's been out of print for a while), but instead spent about $50 on a hardcover edition. It's that good.
If you're into legends, pick up "Myths and Legneds of the Martial Arts" by Peter Lewis.
