Correspondence, manuscripts, subject files, and printed materials of Afrikan P. Bogaevskiĭ. The bulk of the collection concerns emigre Cossacks in Europe, but there are also materials from the Civil War. There are letters from such White Generals as Petr Krasnov, Aleksandr Kutepov, and Petr Wrangel, and many letters from various persons to Bogaevskiĭ's widow after his death. Manuscripts include Bogaevskiĭ's addresses ("obrashchenii︠a︡") to the emigre Cossacks and his memoirs about the Cuban campaign of 1918. Subject files concern the Civil War, emigre Cossacks and related matters. Printed materials touch on Bogaevskiĭ's death and funeral.

Most of the collection concerns the Cossacks in the emigration in the 1920s. Correspondents include Petr Krasnov, Aleksandr Lukomskiĭ, Afrikan Bogaevskiĭ, and Grand Duke Nikolaĭ Nikolaevich. There are White intelligence reports from the Civil War in the south, and manuscripts, correspondence, and mimeographed bulletins relating to the Cossacks in Europe in the 1920s. Printed materials consist of anti-Semitic Russian publications, including issues of "Nat︠s︡ii︠a︡" and "Zhidoved" from the 1930s.
