Maps of the Soviet forced labor camps, the “Gulag,” are some of the most dramatic and best-known Western propaganda images of the Cold War, among “the most widely-circulated pieces of anti-Communist literature.” Barney 2015, 120; see generally ibid. 117-133. The collection includes a number of these, from 1945 to 1982; see Subjects > Communism & Cold War.
This large fold-out map is a successor to those earlier versions. It appears in a 1982 "Guidebook" providing extensive details about Soviet detention facilities of all kinds. Each location is numbered and identified, with supporting material in the Guidebook. The point of the map is not the specific location of any camp indeed, the scale of the map and the size of the dots would make it virtually impossible to use for that purpose.
