The Cato Institute is a non-profit public policy research foundation. Its libertarian focus on limited government, individual liberty, free markets and peace have made for some of the best policy research available anywhere. Its focus is most consistent with the direction of the founders of our nation. Much of the site requires a subscription, but the “Research Areas” and “Publications” sections have a huge volume of information available to those interested in public policy. Cato’s Congressional Handbook is almost required reading for US Congressmen (although they never seem to follow it.)
