The Harvard University Gazette announced that Harvard's Project on the Soviet Social System is now online. Much of what I saw was in English, so it looks like something students could take on as a research project.
Conducted between 1950 and 1953, the Harvard Project on the Soviet Social System includes oral interviews with more than 700 refugees from the Soviet Union, along with several thousand written questionnaires. The goal of the project was to document the life of ordinary Soviet citizens from about 1917 until the outbreak of World War II. Interviewees were Soviets who found themselves outside their country at the end of the Second World War, and were therefore more willing to talk to researchers.
