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 between 1930 and present day. 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, the principal investigators, as well as software for use with this and other network data.
