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.
