Hello, I am interested in doing primary source research on soviet policing (specifically relating to the secret police and their influence on the everyday lives of people) and was wondering if anyone here had any suggestions on where to start?
soviethistory.org might have a few sources for you.
http://digitalarchive.wilsoncenter.org/
That one is a huge archive. It's more geared towards the Cold War and I've used it for foreign policy stuff but perhaps it may have some stuff in there for you.
