Where can one find old Russian scientific papers in physics, say, in the Proceedings of the Russian Academy of Sciences or Zhurnal Eksperimentalnoy i Teoreticheskoy Fiziki? Can they be found online somewhere?
JETP english archive (73-96), may be found here http://www.jetp.ac.ru/cgi-bin/e/index . Russian archive also starts at 73, so I think earlier versions may be found in libraries only.
I found some issues of Proceedings of the RAS here: http://elibrary.ru/issues.asp?id=7781 in Russian only. It seems that they are not translated at all. And normal electronic version does not exists even for Russian.
