Russia's Iron Age established Chamberlin to those who did not know him through the pages of the Christian Science Monitor, as one who could present factual material on Soviet Russia dispassionately, clearly and with the result that other aspects of the Russia scene took on new meaning. Now comes a definitive history of the years 1917 to March 1921, when Lenin put the New Economic Policy into effect. The entire period is treated with rare perspective, thoughtful weighing of cause and effect, and a certain vigor and dramatic molding of material to give it force and meaning. Not a book for anyone wishing to get a birds-eye-view, for it is very long (two volumes), and meticulous as to chronological handling of detail. An important book for reference shelves and for the rounded library on things Russian.
