The Amicus Curiae Networks Project collects and organizes data from all the interest groups that have signed onto a United States Supreme Court amicus curiae brief since 1930. The signatory data is complemented with basic information about each of the interest groups in order to arrive at an understanding of the purposive and coordinated behavior of this comprehensive collection of organizations.

We invite you to learn more about recent developments of the Project by exploring the news to the left. In addition, the menu bar above links to more information on the use of the data sets, our dedicated team and our software for use with this and other network data.
