If ever you go to Minneapolis, a must stop is the Resource Center of the Americas, a wonderful activist center that inspired the hell out of me. The center has a really great little library and it’s just built its website (with an online catalogue!) (Thanks Chris!)
While you’re at it, you could also become a member and receive a great membership newsletter, Connection to the Americas, that reviews all of the human rights and social justice issues in Central and South America. It was maybe one of the best presents I ever got!
