In October of 1967, on the eve of the fiftieth anniversary of the Bolshevik Revolution, the Hoover Institution at Stanford University sponsored a week-long conference on "Fifty Years of Communism in Russia." In addition to the United States, participants came from Great Britain, Germany, France, and Canada--and the Soviet Embassy in Washington was also concerned enough to send several observers. The papers included in this volume give a well rounded picture of all aspects of the first fifty years of Soviet history: Bertram D. Wolfe, "Marxism and the Russian Revolution"; Leonard Schapiro, "The Basis and Development of the Soviet Polity"; G. Warren Nutter, "The Soviet Economy: Retrospect and Prospect", John N. Hazard, "Rigidity and Adaptability of Soviet Law"; Ivo J. Lederer, "Soviet Foreign Policy"; Jean Laloy, "Proletarian Internationalism", Raymond L. Garthoff, "Military Theory and Practice"; John Turkevich, "Fifty Years of Soviet Science"; Max Hayward, "Themes and Democratic Challenge to Communism."
