The papers consist of correspondence, manuscripts, subject files, financial records, photographs, and printed materials. Among the correspondents are Ivan Bilibin, David Burli︠u︡k, Franz Theodor Csokor, Vasiliĭ Kamenskiĭ, and Percival Wilde; there is one item each from Jean Anouilh, Collete, Mikhail Fokine, Vasiliĭ Kandinskiĭ, Vladislav Khodasevich, Pavel Mili︠u︡kov, and Dmitriĭ Merezhovskiĭ. Most of the manuscripts are by Evangulov and Nadezhda Teffi, and memoirs by Evreĭnov's wife, Anna Aleksandrovna, on such topics as her career in the emigration from 1925. There are photographs of Evreĭnov, Nikolaĭ Rimskiĭ-Korsakov, and Vasiliĭ Kamenskiĭ. This collection is almost entirely concerned with the emigration.

Most of the collection concerns the Russian emigration in interwar Europe; a sizeable part deals with the Kadet (Constitutional Democrat) Party in the Russian Civil War. There is correspondence, manuscripts, subject files, photographs, and printed materials. There are many letters by liberal figures, such as Astrov, Viktor Chelishchev, Petr I︠U︡renev, Aleksandr Kizevetter, Pavel Mili︠u︡kov, Vladimir D. Nabokov, Vladimir Obolenskiĭ, Panina, and Ivan Petrunkevich. There are also letters from Ivan Bilibin, Alice Masaryk, and Thomas Masaryk. Manuscripts are chiefly by Astrov, and include memoirs, poems, and lectures. There are also memoirs by Panina, and eulogies by various people on Astrov. Subject files from 1917-1920 have materials on Panina's arrest and trial by the Bolsheviks, Kadet conferences, protocols of meetings of the Kadet Party central committee, and other items. Files on the emigration deal with the Russkiĭ Ochag (Russian Hearth) and other bodies, especially in Czechoslovakia. There are photographs of Astrov, Kizevetter, Nikodim Kondakov, Alice Masaryk, Panina, and others. Printed materials include books, clippings, and offprints by Astrov and others.
