Most of the materials are from the years after World War II, and concern the organizations with which Lampe was affiliated. There is correspondence from members of the Romanov family, especially Grand Prince Vladimir Kirillovich, and from Alekseĭ Arkhangelśkiĭ, Ivan Ilín, Vasiliĭ Orekhov, and others of Lampe's emigre military and monarchist colleagues. Photographs deal with such topics as the Romanov family, the Civil War, the emigration, World War II, and with Lampe himself. Besides the post-1945 materials in the collection, smaller groups of materials concern 18th and 19th century Russian military history (including a letter signed by General Aleksandr Suvorov), the interwar period, and ROVS in Germany during World War Il.

The collection consists of correspondence, manuscripts, subject files, questionnaires, photographs, and printed materials. Cataloged correspondents are Ilín, Anton Denikin, Ivan Shmelev, Boris Zaĭt︠s︡ev, and Kirill Zaĭt︠s︡ev. Correspondence primarily concerns the Russian embassy in Stockholm through 1920 and the Russian Christian Labor Movement (1931-1940). Manuscripts are mostly by Ivan Ilín on anti-Communist topics. Subject files generally concern conferences of the Russian Christian Labor Movement, and also contain information on the Conference Economique des Allies a Paris (1916), the Russian embassy in Stockholm, and Witte's visit to Norway in 1894. Questionnaires, photographs and printed materials mostly deal with the Russian Christian Labor movement. Printed materials contain issues 7-91 of the periodical "Novy put"́ of the Bureau of Russian Christian Workers. The great majority of this collection concerns the Russian Christian Labor Movement.
