Did not know Volkogonov was translated. Start there.@2Glocks, I'm not at the house to look at my library right now & I'm drawing a blank on the 1916 revolution specifically. i'll add to this when I get home.
For a very readable & good summary of the precursors:
Barbara Tuchman, The Proud Tower is a brief history of Europe from like 1890 til the outbreak of World War I
Robert Service, Lenin is a very good biography
Dmitri Volkogonov (3 books), Autopsy of an Empire: The 7 leaders who built the Soviet Regime, Stalin: Triumph & Tragedy & Trotsky: The Eternal REvolutionary
Jack Reed, 10 Days That Shook the World Reed was an American socialist & journalist, very sympathetic to the Soviets & present during the revolution in Russia. One of the few Americans buried in the Kremlin Wall Necropolis. Made into a movie with Warren Beatty as Jack Reed.
Brian Crozier, The Rise & Fall of the Soviet Empire obviously cove3rs the revolution in the early sections of a massive book.
Piers Brendon, The Dark Valley: A Panorama of the 1930s is a survey of the period which saw the rise of Stalin, Hitler & Mussolini.
All I got off the top of my head right now.
Colonel General. He had access to Soviet archives before anyone else did.
