Not sure what level or type of book you are considering, art, composition, technique, lighting?
Anything by Scott Kelby, Joe McNally, Joel Sartore, Bryan Peterson and Ansel Adams.
However, you might have a great time going to HALF PRICE BOOKS after dinner one night and going over what they have. That's always fun and I've found some gems from as far back as the '70's. One I got that is lots of fun to look at is a large thin book by Mary Ellen Mark and Annie Leibovitz from 1974. It has some great images from that time including a great shot of Canice Bergen shortly after her father passed away.
I've learned a lot from just looking at pictures and trying to see what works in them and makes them interesting and distinctive.
