Twenty years in the making, this collection presents 122 top-level Soviet, European and American records on the superpowers' role in the annus mirabilis of 1989. Consisting of Politburo minutes; diary entries from Gorbachev's senior aide, Anatoly Chernyaev; meeting notes and private communications of Gorbachev with George H.W. Bush, Margaret Thatcher, Helmut Kohl and Fran ois Mitterrand; and high-level CIA analyses, this volume offers a rare insider's look at the historic, world-transforming events that culminated in the collapse of communism in Eastern Europe and the end of the Cold War. Most of these records have never been published before.
