Correspondence, manuscripts, photographs, subject files, and printed materials of Evgenii Aleksandrovich Vechorin, chiefly concerning alumni of the St. Petersburg Polytechnical Institute. The catalogued correspondence includes letters from Nikolai Andreev, Petr Savitskii, Igor ́Sikorskii, Gleb Struve, and Alfred Swann, and other prominent figures. Much of the arranged correspondence is from fellow graduates of the Institute, and concerns alumni affairs. Most of the manuscripts are likewise by fellow graduates; many are memoirs, such as those by Vechorin himself, while others concern technical subjects. Among the subject files are biographical sketches of Institute graduates and files on such individuals as Petr Savitskii, Igor ́Sikorskii, and Alfred Swann. There are several photographs taken at the Institute ca. 1900 as well as photographs of Vechorin and his colleagues after emigration. The printed materials include clippings and excerpts, miscellaneous journals, and books by Vechorin and S. P. Timoshenko.

Correspondence, manuscripts, documents, photographs, subject files, printed materials, and memorabilia of historian George Vernadsky (Georgii Vladimirovich Vernadskii; 1887-1973). Most of the collection consists of his personal and professional papers, circa 1918-1973. Sizable groups of materials also concern members of his family, especially his wife Nina (1884-1971); his father, scientist Vladimir I. Vernadskii (1863-1945); his mother Nataliia E. Vernadskaia (1860-1943); and his sister Nina V. Toll' (1898-circa 1976).

The papers comprise correspondence, manuscripts, memoirs, diaries, personal documents, photographs, printed materials, periodicals, and clippings relating to the life and professional activities of Nataliia Logunova, a Russian émigré journalist and writer.

Collection of Russian and Eastern European emigre newspapers and periodicals published in Europe, North America, South America and Australia in the 20th century, also includes a number of newspapers published in Russia and the Soviet Union.

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.
