The collection consists of manuscripts, memoirs and a printed item. Manuscripts consist of poems by Maĭborodov, including a typescript of a poema entitled "Bogdan Khmelńit︠s︡kiĭ." The memoirs primarily concern the years 1900-1938 and include Maĭborodov's reminiscences as a student at St. Petersburg University (1900-1904) and his reminiscences of his service as a zemstvo chief in the Volyni︠a︡n, Podoli︠a︡n, Bessarabian and Kherson provinces from 1904-1916. The printed item is an off-print (61 p.) of a memoir entitled "S frant︠s︡uzami," which was published in "Arkhiv Russkoĭ Revoli︠u︡tsii." In the collection it is part of the memoir "Vo vremi︠a︡ smuty (pri vremennom pravitelśtve) [1917-1920]."

Manuscript memoirs (ca. 200 p.) in the form of 20 brief essays. The memoirs cover the period 1900-1920.

Shneerov's typescript memoirs concern his life up to 1921. The longest manuscript is entitled"V pogone za sineĭ ptit︠s︡eĭ" (472 p.), and covers the period from his childhood to his arrival in the United States in 1921; it goes into particular detail on his years as an active revolutionary (1902-1908), and on 1917-1920. Two shorter manuscripts appear to be largely translated excerpts from the longer work: "When I was young" (80 p.), and "My last arrest and state prison of Kursk" (49 p.). Shneerov joined the Socialist Revolutionary Party in the first years of the 20th century. He was first arrested and exiled in 1903, but escaped and went to Western Europe (Switzerland, Austria, France, England). He came back to Russia in 1905, and continued revolutionary activities until arrested and exiled again to Siberia in 1908. In 1912-1916, he lived in the Far East, in Harbin, Japan, and Shanghai; he lived in San Francisco in 1916-1917, returning to Russia after the February 1917 Revolution. In 1917 he was a minor government official in Tambov, and in 1918 was sent by the government to the Far East on a mission to obtain supplies. He spent 1918 in Vladivostok, Manchuria, and China, and 1918-1920 in Japan. In his memoirs, besides his own experiences, he also discusses minor and major revolutionaries whom he knew, such as Osip Minor, Grigoriĭ Gershuni, and Evno Azef. The Hoover Institution also has copies of these memoirs.

Mandrazhi's typescript memoirs "Begin at the Beginning" discuss such topics as his military education, the Corps of Pages, the Russo-Japanese War, World War I, the 1917 Revolution, and the Civil War in the South.

The memoirs are in two series: Golit︠s︡yn's typescript "Vospominanii︠a︡" (453 p. in 17 notebooks), which cover his childhood and youth, his "period of social and political service (1900-1917)", in World War I, and the Revolution and Civil War; and a manuscript in two notebooks entitled "Vtoroĭ god Russkoĭ Revoli︠u︡t︠s︡ii: Bolśhevizm na Ukraine; Getmanskiĭ perevot; Petli︠u︡rovshchina" (410 p.), which discusses the Civil War in the Ukraine.

Typescript memoirs consist of a bound volume and some loose pages (in all 361 p.). The memoirs cover Kisel-́Zagori︠a︡nskiĭ's childhood, education, his years as a provincial official, the Revolution of 1917 and Civil War, and emigration in Turkey. Also included are two photographs of him.

Memoirs of the Koshko family, specifically Ivan Frantsevich, his brother Arkadiĭ, his son Boris, and his daughter Olǵa. Almost all of the memoirs are in the hand of Olǵa Koshko. Ivan's memoirs (partially published) touch on his government service in Samara, Novgorod, Penza, and Perḿ and his experiences during the 1917 Revolution and Civil War. The excerpt from Arkadiĭ's memoirs concern the Beilis ritual murder case. Boris Koshko's memoirs concern his experiences as an Imperial and Provisional government official during World War I. Olǵa Koshko's memoirs deal with her father and with life in the emigration in Europe.

The collection consists of Cherkasskii's memoirs of World War I and the Civil War; brief memoirs by his father, Mikhail Alekseevich Cherkasskii, who served in the Imperial central government and as governor of Simbirsk before the 1917 Revolution; and manuscripts by other people, particularly G. N. Odintsov. There are also documents of I. M. Cherkasskii and photographs.

One letter, manuscripts, and printed materials of Aleksei Fedorovich Girs and of his wife, Liubov' Aleksandrovna Girs. The letter, dated 1914, when Girs was governor of Minsk, is addressed to N. A. Maklakov. Aleksei Gir's memoirs cover such topics as his service in Estland; Petr Stolypin; the "Jewish question;" Tsar Nicholas II; and independent Estonia, where he lived in 1918-1924. There are also two reports by Girs from the time of his service in Minsk. ́Liubov Girs is represented chiefly by diaries from 1901-1918, particularly on Odessa in 1905-1906; Stolypin's murder in 1911; and Nizhny Novgorod in 1917. Among the printed materials are announcements of Gir's accession to the Minsk governorship in 1914-1915.

The papers consist of correspondence, manuscripts, subject files, and printed materials. Correspondence includes letters by Vladimir Kokovt︠s︡ov, and letters concerning the posthumous publication of Kryzhanovskiĭ's memoirs. Manuscripts include drafts of these memoirs and other items by Kryzhanovskiĭ. There are also manuscripts, chiefly memoirs, by other persons; most were evidently sent to Kryzhanovskiĭ as editor of the emigre journal "Russkai︠a︡ Letopis"́ in the 1920s, but were never published. They deal with such topics as the Imperial police and government and the 1917 Revolution and the Civil War. There is a large group of manuscripts and related printed items, evidently prepared by Kryzhanovskiĭ, on the projected governmental system of a post-Bolshevik Russia. Subject files deal with the 1917 Revolution, emigre monarchism, and other topics.
