McGann and Weaver are two of the leading scholars on think tanks and they have done an excellent job of painting the think tank landscape around the world. Thinks Tanks and Civil Societies: Catalyst for Ideas and Action is a comparative study of public policy research organizations and their role in public policy process around the world that deserves to be read by scholars and practioners alike. I found the regional overview chapters to be particularily informative. This book has a wealth of information in it and will prove to be an inportant reference work on the subject. I recommended it highly for domestic and international donors who support these institutions, policy makers and the media who use their products and pundits and the public who relies on them for ideas and action.
