The list below, enumerates the selected sites of the Soviet forced labor camps of the Gulag, known in Russian as the "corrective labor camps", abbreviation: ITL. Most of them served mining, construction, and timber works. It is estimated that for most of its existence, the Gulag system consisted of over 30,000 camps, divided into three categories according to the number of prisoners held. The largest camps consisted of more than 25,000 prisoners each, medium size camps held from 5,000 to 25,000 inmates, and the smallest, but most numerous labor camps operated with less than 5,000 people each.[1] Even this incomplete list can give a fair idea of the scale of forced labor in the USSR.
A list of Gulag penal labor camps in the USSR was created in Poland from the personal accounts of labor camp detainees of Polish citizenship. It was compiled by the government of Poland for the purpose of regulation and future financial compensation for World War II victims, and published in a decree of the Council of Ministers of Poland.[2]
