Correspondence, manuscripts, documents, photographs, subject files and printed materials of Urusov. Urusov began his diplomatic career at the Vatican, and subsequently served in Bucharest (1880-1886), Brussels (1886-1898), Paris (1898-1903), Rome (1903-1904), and Vienna (1904-1910). The collection includes letters from Thʹeophile Delcassʹe, Nikolaĭ Giers, Aleksandr Gorchakov, Aleksandr Izvolśkiĭ, Vladimir Lamzdorf, King Leopold II, Alekseĭ Tolstoĭ, and Pauline Viardot-Garcia. There is a photocopy of a poem by Pushkin. The arranged correspondence primarily concerns Urusov's professional affairs, but also includes family letters. There are manuscripts by a number of people; most (including Urusov's own) relate to Russian diplomacy. The manuscript by P.V. Vogak discusses his service with the Red Cross during World War I, and includes material by I.N. Urusova (Urusov's wife), who was a Red Cross nurse. There are a number of documents Urusov received during his diplomatic service. Among the printed materials are two folders of clippings (some of which discuss Urusov) and several booklets and pamphlets.
