Martin Mccauley 
Soviet Union 1917-1991 [PDF ebook] 

A second edition of this famous survey has been eagerly awaited. When the first edition appeared Brezhnev was still in power, Gorbachev did not make it to the index, and the USSR was a superpower. Today the Soviet experiment is over and the USSR no longer exists. How? Why? Martin Mc Cauley has reworked and greatly expanded his book to answer these questions, and to provide a complete account of the Soviet years. Essential reading to an appreciation of recent history — and to a better understanding of whatever happens next.
