The Granat Encyclopedic Dictionary (Russian: Энциклопедический словарь Гранат) is a Russian encyclopedic dictionary originally published in 58 volumes with one supplement throughout both the Tsarist and Soviet periods. The dictionary's full title is The Encyclopedic Dictionary of the Granat Russian Bibliographical Institute (Russian: Энциклопедический словарь Русского библиографического института Гранат). The word "Granat" refers to the last name of two brothers, (1861 - 1933) and (1863 - 1941), who commissioned the articles in their Moscow office (Ignatiy Granat was later executed by shooting).
