Work on the CCP began at the University of Illinois, where Zachary Elkins and Tom Ginsburg were faculty members and James Melton a Ph.D. student. Since then, the project has expanded to the University of Chicago, the University of Texas, and University College London. We gratefully acknowledge the financial support over the years from each of these institutions, as well as that of Google Ideas, the Indigo Trust, International IDEA, the National Science Foundation (SES 0648288), the Thomas J Reinhart Foundation, and the United States Institute of Peace.

cline_logo_0We owe a very special thanks to the Cline Center for Advanced Social Research, which served as the project’s initial administrative and intellectual home. Our efforts to conceive and launch the project would not have been possible without the assistance and encouragement of the Cline Center’s founding director Peter Nardulli. Under the leadership of current director Scott Althaus, the Cline Center continues to support and collaborate with the CCP, for which we are incredibly grateful.

We thank Kalev Leetaru for his excellent work in building the text digitization and coding infrastructures, and Tom Redman for his work to update and expand upon the tools. We are also grateful to the members of our advisory board for their thoughtful and generous guidance.

Finally, we thank HeinOnline and Oxford University, publishers of World Constitutions Illustrated and Constitutions of the World, respectively, for use of their valuable material.
