Memoirs consist of a continuously-paginated manuscript (326 p.), and two typescript and five manuscript essays. His memoirs cover from the 1890s to 1918, and concern primarly his professional activities. Political events dealt with include the 1905 and 1917 Revolutions (with particular attention paid to the participation of railway personnel), and Dmitrenko's work as an active member of the Constitutional Democratic (Kadet) Party in 1905-1906.

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.

Mikhaĭlov's largely typescript memoirs discuss his experiences in the early part of the Civil War, his education, Grodno in 1905, and the Orthodox Church in China (including two photographs).

The collection consists of memoirs, manuscripts and a few related photographs. The memoirs cover Nevzorov's reminiscences of the 1905 Revolution through the 1917 Revolution.

The memoirs discuss such things as his career, the investigation into the 1905 Odessa pogrom, the period 1917-1919 in Kherson, and the emigration in Constantinople and France.

The collection includes Pli︠u︡shchevskiĭ-Pli︠u︡shchik's diaries for 1905-1909 (covering the Russo-Japanese War, and the 1905 Revolution) and 1914-1920 (covering World War I, the 1917 Russian Revolution and the Civil War). Among other manuscripts are a memorandum prepared by General Denikin's staff for the allied missions upon their arrival in Ekaterinodar (Nov. 1918) and Pli︠u︡shchevskiĭ-Pli︠u︡shchik's obituary of General Ivan Romanovskiĭ. There is also a photograph of Pli︠u︡shchevskiĭ-Pli︠u︡schik and Romanovskiĭ at Imperial Staff Headquarters in Mogilev in 1917.

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.
