>Given its obvious significance, it's surprising that not a single volume has circulated online like many other books.
It's not surprising at all. Many "official" texts published in the USSR, especially the late USSR, were a mishmash of state-approved ideology and dogma. I tried reading Brezhnev's autobiography (or just biography?) and it was absolutely worthless. It was full of truisms like, "He always works well with others, and always asks for everyone's opinion before making a decision."
