Surely, more has been written about the Russian Revolution and the ensuing forty years of Soviet rule than about any comparable episode in human history. The bibliography of items on the French Revolution occupies, it is said, one wall of the Bibliothéque Nationale. A complete bibliography on the Soviet Union—which is yet to be compiledand may never be because of the geometric rate at which it multiplies—would probably make that earlier cenotaph to scholarship shrink the way in which the earlier tombs diminished before the great complex at Karnak.
