Manuscripts by Voronkov. One manuscript is a short (6 p.), handwritten, autobiographical essay, in which Voronkov mentions his military education, his service in the Russian Imperial Army, his management of a military factory in WWI, and his emigration after the Civil War. The other manuscript"Svi︠a︡tai︠a︡ Ruś" consists of 80 poems written by Voronkov primarily about Imperial Russia, Russian Orthodoxy and the Romanov family. The collection also includes a copy of a Russian emigre newspaper published in Argentina ("Nasha Strana" 15 Feb. 1966) that contains an article about Voronkov's poems.

The memoirs primarily concern aristocratic life and the Imperial court in St. Petersburg in the early 20th century. A version of Geiden's memoirs has been published as Heyden, Marina de "Les rubis portent malheur", Monte-Carlo, Regain [1967], 315 pp.

Collection includes two postcards written by the Grand Duchess Tati︠́a︡na; part of a letter by an unidentified person; and three manuscript memoirs by Fedchenko. The memoirs discuss the Archbishop Feofan of Poltava; Fedchenko's aunt, Marii︠a︡ F. Geringer, lady-in-waiting to Empress Alexandra; and General Dmitriĭ D. Fedchenko.

The memoirs of Grand Duke Romanov consist of a typescript and a photocopy, entitled "Vospominanii︠a︡: Semeĭnai︠a︡ Khronika, 1887-1919" (1,171 p.) and photographs for the memoirs. There are also related family materials, which are mostly excerpts from letters of his father, Konstantin Konstantinovich, and his grandfather, Konstantin Pavlovich. They are grouped by subject. The memoir covers the early years of Gavriĭl Konstantinovich's life, before he left Russia in 1918.

Tal'́s handwritten memoirs, recorded in 88 notebooks, recount his life experiences and explore in detail the following subjects: the life of the Imperial family and the role of Rasputin; high society and cultural life in St. Petersburg at the turn of the century; social life and customs in the Russian provinces during the 19th century; the Aleksandrovskiĭ Lycʹee; military education and the Hussar Regiment; the February and October Revolutions; and the Russian emigration, first in Yugoslavia and, after World War II, in France. The narrative, although predominantly second-hand, is frequently interspersed with personal reminiscences and the recollections of family members, friends and colleagues. Georgiĭ Tal ́stresses the eyewitness aspect of these accounts, stating that he recorded much of the information the time it occurred. However, his repeated use of verbatim dialogue gives the memoirs a tone of historical fiction.
