Founded by the Ukrainian Liberation Council in 1957, Prolog holds a collection of materials dating from ca. 1941 to the early 1950s. The holdings, in approximately 2 4-drawer filing cabinets at present, include documents and publications of the anti-Nazi Ukrainian underground in World War II; typed reports of the underground Ukrainian Insurgent Army (an organization of Ukrainian nationalists); photographs of Ukrainian leaders, military formations, and related subjects; correspondence from the war years and to about 1950; leaflets—anti-Nazi and anti-Soviet of the underground, plus Nazi and Soviet matter; and some German official announcements (e.g., death sentences pronounced against members of the Ukrainian underground). All of these materials remain the property of the Ukrainian Liberation Council; they are open to qualified researchers.
