Amazon book reviews and never buy a book you haven't held in your hands, are pretty much the two rules I follow. The idea is basically widen what books in the field you have heard of through amazon, then get a hold of them some how(I usually get an inter library loan for a few weeks) to check depth and writing style. So far skipping step two has stuck me with books I didn't really appreciate.
