1917+

I found the site of the State Public Historical Library of Russia, or, more specifically, their electronic library (scanned books, magazines, etc.). There was a book published in the Saratov region in 1923. I know nothing about the author (his surname is very common, so it is hard to google anything relevant to him personally). The literal title is "Short Course of Political Literacy". I think it might be interesting for you. I translated a chapter about the events between February and November of 1917.
