Information about the directory

About the directory

The Open Think Tank Directory captures information about more than 3200 think tanks, policy research centers and related organisations from around the globe. We have not just captured names and websites – our directory includes a wide range of information about the think tanks, including the topics they focus on, how to contact them, and more. This allows for a range of comparisons, which you’ll see throughout the site and as part of our data visualisations of the data set.

We are dedicated to creating an open directory. That means that the whole directory is accesible to all,  downloadable and available under a Creative Commons license. See our Terms and Conditions for more information.


The On Think Tanks Open Think Tank Directory has been proudly supported by:

  • On Think Tanks
  • Open Society Foundations
  • Konrad-Adenauer-Stiftung
  • Quaternary Consulting
  • The Willian and Flora Hewlett Foundation


This directory is the result of a lot of work from a number of contributors working in different capacities.
