The Atlas Economic Research Foundation maintains this Freedom Directory as a service to market-oriented institutes and their interested constituents. It provides contact and program information about think tanks that have shared in Atlas’s work or that pursue a similar vision. t also adds this disclaimer: Atlas’s Freedom Directory compiles information on more than 450 think tanks worldwide. The Directory’s default settings assume users want to search our broadest universe of active think tanks. This may result in listings of institutes that Atlas has not worked with in the past, which may differ in important ways from most market-oriented think tanks.
