Ok, I know this isn't actually a search engine - it's actually an Amazon.com A-Store. But the book choices and categories are mine - not generated by some algorithm. I have not read all the books listed here. Inclusion is based primarily on Amazon rankings and reviews (and my interpretation of those reviews). Category choice is entirely my own typically based on the Table of contents or book previews.

As always, I welcome your recommendations for addtional titles to include.
