The Harvest of Sorrow: Soviet Collectivization and the Terror-Famine is a 1986 book by British historian Robert Conquest published by the Oxford University Press. It was written with the assistance of historian James Mace, a junior fellow at the Harvard Ukrainian Research Institute, who started doing research for the book following the advice of the director of the institute. Conquest wrote the book in order "to register in the public consciousness of the West a knowledge of and feeling for major events, involving millions of people and millions of deaths, which took place within living memory."
