Think Tank Search EngineProvides a way to search all Think Tank information and also all NON US Think Tanks. Created by the Kennedy School of Government at Harvard University.
From the website: "Think Tank Search is a custom Google search of almost 600 think tank websites. For the purposes of this search, think tanks are defined as institutions affiliated with universities, governments, advocacy groups, foundations, non-governmental organizations, and businesses that generate public policy research, analysis, and activity. Inclusion is based upon the relevancy of subject area to HKS coursework and scholarship, the availability of the think tank’s research in full-text on the website, and the think tank’s reputation and influence upon policy making. The list represents a mixture of partisan and non-partisan think tanks."
