Most of the collection consists of letters to Golśteĭn; there are some as well to her second husband, Vladimir A. Gol'shtein. The materials reflect Gol'shtein ties to Russian liberalism and populism and also to both French and Russian art and literature. There are groups of cataloged letters from Renʹe Arcos (15), Mykhailo Drahomaniv (52), Andrʹe Fontainas (31), Renʹe Ghil (32), Viacheslav Ivanov (17), Petr Lavrov (49), Vladimir Vernadskii (20), and Maksimilian Voloshin (29). There are also items by Jurgis Baltrušaitis, Henri Martin Barzun, Henri Bergson, Ivan Bunin, Sergei Diagilev, Paul Fort, Vladislav Khodasevich, Aristide Maillol, and Odilon Redon. Manuscripts are chiefly by Golśhteĭn, and include her memoirs on Drahomaniv. There are also poems by Voloshin and by Konstantin Bal'mont. Subject files deal with such topics as the Russian famine of 1891-92 and the Russian Liberation Committee at the time of the Civil War. There is a copy of Gol'shtein's book, "Serf Life in Russia."

Most of the collection consists of essays, apparently written by Left Socialist Revolutionaries on a variety of topics. Examples include I︠A︡kov Braun "Partii gosudarstvennogo kapitalizma i levonarodnichestvo" "O.L. Chizhikov"Integralńyĭ sot︠s︡ializm v mirovozrennii P.L. Lavrova"B.D. Kamkov"Uroki parizhskoĭ kommuny" and G. Nestroev"O kont︠s︡essiakh sovetskomu pravitelśtvu." Most of the manuscripts were written in th early 1920's. Printed materials include Steinberg's book"Ot fevrali︠a︡ do okti︠a︡bri︠a︡, 1917 g." (Berlin, 192_), Soviet legal publications from the period, and galleys for an article by an unknown author concerning worker fatigue.

The papers consist of correspondence, manuscripts, documents, and printed materials. Correspondence includes 82 letters from Maksim Kovalevskiĭ to the mathematician Sofii︠a︡ Kovalevskai︠a︡; 69 letters from Petr Lavrov to Kovalevskiĭ; and letters to Kovalevskiĭ from Anton Chekhov (typed copies), Nikolaĭ Mikhaĭlovskiĭ, Pavel Mili︠u︡kov, Petr Struve, and Ivan Turgenev (typed copy). Manuscripts consist of Kovalevskiĭ's handwritten memoirs, with a typed copy and some printed excerpts. Documents consist of Kovalevskiĭ's diplomas from the University of Berlin (1873), the Russian Imperial Academy of Sciences (1899), and the Deputazione Veneta di Storia Patria (1901).
