Coffee books

My personal favorite is Coffee Recipes: Customs, Facts, and Fancies. For some reason, I still haven't tried any of the recipes, but I've read the book about a dozen times. Are there any coffee books in your personal library?

ETA: The touchstone wasn't working, so I HTML'd it.

Coffee related, I picked up a copy of The World of Caffeine: The Science and Culture of the World's Most Popular Drug a few weeks ago at a friends of the library sale. Looks interesting.
