One worth considering: The Fourth Part of the World, by Toby Lester. It's a great, absorbing, richly illustrated, makes-you-feel-smarter-and-better-for-having-read-it chronicle of the race to map what became the Americas five centuries ago. Toby Lester explains the idea behind the book in this clip:
There's also a nice Flash-based interactive version of the influential 1507 map at the center of his story, here. Toby Lester is a friend and one-time Atlantic colleague -- but part of the reason we're friends is the sensibility and intelligence he exhibits in this book. Worth checking out.
