"The worldwide sensation created by the appearance in 1961 of a brief poem, "Babi Yar," by Yevgeni Yevtushenko , condemning Nazi and prerevolutionary antisemitism, and the mutilation by Soviet censorship of Babi Yar (1966; Eng. 1967, revised 1970), a documentary novel by Anatoli Kuznetsov about the Nazi massacre of Soviet Jews in a ravine near Kiev, demonstrate that, in contrast to other areas of Soviet life, there was no real thaw in Soviet literature's treatment of Jewish themes."
January 1, 1970
