My small-town public library growing up had a great resource that I did not appreciate at the time: an English translation of the Great Soviet Encyclopedia[0].
I really wish I had spent time with it. If nothing else it would have given me some questions to ask my history teachers.
Wow! I would have been absolutely fascinated by this when I was a kid.
I remember once wandering around my college library and finding the book “The Soviet Economy Through the Year 2000.” This occurred during the current millennium.
