Here are a couple of reviews:
1. Here's a shorcut to some stuff you never knew you needed to know. It'll save you time with a capital "T".
2. Not a book you want to read for pleasure but, for anyone doing research on international relations - a hot topic these days - at a cost of less than a minute of your time, it can save hours. That's a bargain!
