Pi Sigma Alpha was founded in 1920 at the University of Texas for the purpose of bringing together students and faculty interested in the study of government and politics. I belong to several discussion groups. I learn what concerns others who share my professional interests. I learn innovative practices and how others solve problems similar to my own. I hear about seminars, workshops, conferences, etc. in my field.
Members often share citations for significant articles and books.
Here is a site for a catalog of discussion groups in political science. Notice the publishers of these selected journals. Foreign Affairs . New York, Council on Foreign Relations. Washington, etc., Carnegie Endowment for International Peace, etc.
