The contents of the collection include: correspondence, manuscripts, minutes of "Zagranichnai︠a︡ Delegat︠s︡i︠a︡" meetings from the 1920s, and financial records both from the Party organization in Russia (1908-1915) and from its Estonian and Finnish affiliates (1922).

Correspondents which figure prominently in the collection are: Nikolaĭ D. Avksentév, Viktor M. Chernov, Ili︠́a︡ I. Fondaminskiĭ, Osip S. Minor and Vladimir M. Zenzinov; there is one letter by Azef. Much of the pre-1920 correspondence is addressed to Mark A. Natanson; after 1922 a large number of the letters are addressed to Sergeĭ P. Rostnikov.
