Thanks to Adam Beauchamp, Social Sciences Librarian at Tulane University's Howard-Tilton Memorial Library, for allowing us to reproduce this beautifully done guide version of James McGann's Think Tanks rankings.
The Global "Go-To Think Tanks" is a comprehensive ranking of the leading think tanks worldwide. The report was written by Professor James McGann, director of the Think Tanks and Civil Societies Program at the International Relations Program at the University of Pennsylvania.
Direct links to each think tank website ranked in the listings are provided where available.
The rankings in this guide reflect the 2011 report. It will be replaced by the 2012 report rankings, which can now be viewed in text form here.
Think tanks are public policy research institutes that provide research, independent analysis and advice on domestic and international issues. These organizations employ experts from academia and government who publish a wide range of scholarship including working papers, proceedings from conferences, books, journals and policy briefs. To date there are nearly 6,545 of these organizations currently operating worldwide.
