There are actually lots of good books on AMO physics out there. Here are a few I have learned from; tell me your favortives, and I can include them here, too. Some of there are availalbe on reserve in the Math/Phys library, others are on the library shelves, some may belong to a friend or colleague, and most are available at Amazon.
