The word Gulag was not often used in Russian, either officially or colloquially; the predominant terms were the camps (лагеря, lagerya) and the zone (зона, zona), usually singular, for the labor camp system and for the individual camps. The official term, "correctional labour camp", was suggested for official use by the Politburo of the Communist Party of the Soviet Union in the session of July 27, 1929.
