The collection chiefly consists of Goldenweiser's American legal case files. There are also case files from his German years, and substantial materials on his research into the condition of Russian refugees and refugee problems in general in the 1930s. Much of the correspondence from the late 1930s and early 1940s concerns Jews in Germany and occupied Europe. Correspondents in the collection include Mark Aldanov, Abraham Cahan, Antal Dorati, Georgiĭ Florovskiĭ, Tatʹi︠a︡na Frank, Vladimir and Vera Nabokov, and Mikhail Karpovich; there are 1 or 2 items each from Dwight D. Eisenhower, Eleanor Roosevelt, Herbert Lehman, and Nikolaĭ Losskiĭ. Letters, manuscripts, and documents by Vera Nabokova contain considerable information on her and her husband's lives in Germany and in the United States. Many of the American case files concern (as does much of the Nabokova material) individual claims for reparations from Germany after World War II.

Correspondence, manuscripts, notes, documents, photographs and printed materials of Frank. The collection reflects almost every aspect of his career, but especially his life in Germany, France, and England after his expulsion from Russia in 1922. Among the correspondents are Nikolaĭ Berdi︠a︡ev, Sergeĭ Bulgakov, Albert Einstein, Georgiĭ Florovskiĭ, Nikolaĭ Losskiĭ, Fedor Stepun, and Petr Struve; there are one or two items each from Vi︠a︡cheslav Ivanov, Bernard Pares, and Alekseĭ Remizov. There are also many letters from Semen Frank and his wife Tati︠a︡na to their son Viktor, and from Peter Struve's family to the Franks. Manuscripts for several of Frank's books are in the collection, such as "Svet vo tḿe" "Realńost ́i chelovek" and "Biografii︠a︡ P.B. Struve." Other manuscript materials by Frank include essays and lectures, outlines of courses he taught as a professor in Russia before his expulsion, and notebooks. There are also two poems by Vi︠a︡cheslav Ivanov. Among the printed works are Frank's Bible and offprints of his articles. There are photographs of Sergeĭ Bulgakov, Fedor Stepun, and of the Frank and Struve families.
