The Alden Library archives has enough info on the student movements of the 60s and 70s to keep you there all day. Contact archivist Bill Kimok if you want to see items in person or desire more information.
This page describes where in what formats local papers are available. Especially important for student history is The Post, of course. You will want to scan widely, and consider many different applicable words: Viet Nam War Protests, Civil Rights Movement, Student Activism, etc.
