Stalin's Letters to Molotov, 1925-1936: Russian Edition

This very interesting book exists thanks to inadequate means of communication and also to Molotov himself.He gave the original letters to the authorities long after Stalin's death.The letters are of great importance as they go beyond the formal language used in correspondences.The problems facing the new Soviet republic are mentioned in letters in everyday language.The book has to be read with other books related with the period as there are several broken links between letters.Could be read as a preliminary for studying the Soviet Union in 1930s.
