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.[1] 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."[2]: 149
