Introduction to Artificial Intelligence: Second, Enlarged Edition (Dover Books on Mathematics) 2, Philip C. Jackson - Amazon.com

I actually picked up this book at the discount bin at a local bookstore. I had always been interested in A.I research, and this deal was irresistable. However, I think this book is worth alot more, and provides more insight into the field than many of the current popular books on the subject. This book basically goes into A.I research and leaves alot of the philosophical issues at a minimum. Basically you can look at this as a real text book about the subject of A.I.
