Socialist Revolutionary Party.

The papers (1904-1939) document many activities of the Socialist Revolutionary Party (Partii︠a︡ sot︠s︡ialistov-revoli︠u︡t︠s︡ionerov), especially of the Party's "Zagranichnai︠a︡ Delegat︠s︡ii︠a︡" (Foreign Delegation). The collection, which for the most part concerns the period after 1920, represents only a fraction of the entire S.R. Archive; another portion is housed at the International Institute for Social History in Amsterdam, while material deposited with the Russian Historical Archive in Prague were transferred to the USSR.
