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, photographs, subject files and printed materials. The correspondence includes letters from Michael Florinsky, Mikhail Karpovich, Bernard Pares, Geroid Robinson and George Vernadsky as well as one each from Lidii︠a︡ Lopukhova, Lewis Mumford and George Orwell. There is abundant correspondence relating to the Cunard Whitestar Line, notably from Anthony Cunard. The manuscripts include drafts of several of Fedotoff-White's books as well as copious notes and book reviews. There are subject files relating to his curriculum vitae, financial affairs, and his university studies. Among the printed materials are books (including several of his own), clippings, pamphlets, and brochures.

The papers consist of correspondence, manuscripts, documents, and printed materials. Correspondence includes 3 letters from Mikhaĭl Karpovich, and letters from Khmelńit︠s︡kai︠a︡'s son Sergeĭ, a writer in the Soviet Union. Among the manuscripts is Khmelńit︠s︡kai︠a︡'s autobiography, which discusses her childhood in Odessa and her education; and her translation of the letters of William Frey, a Russian immigrant in Kansas in the 1870s.

These papers consist of correspondence, manuscripts, documents, and printed materials. Most of the correspondence concerns Florinsky's publications and editorial work. Among the correspondents are Boris Bakhmeteff, Michael Karpovich, Aleksandr Meyendorff, Bernard Pares, James T. Shotwell, and Dmitriĭ Svi︠a︡topolk-Mirskiĭ: there are one or two items each from John Dewey, Herbert Hoover, Edwin Seligman, and Harry S. Truman. Manuscripts by Florinsky include his "Russia: A Short History" and some minor articles and book reviews. Other manuscripts include a poem by Bernard Pares and a study by Sergeĭ Prokopovich of the Soviet five-year plan of 1946-50; there is also a photograph of Meyendorff. Documents concern Florinsky's career at Columbia and also include book contracts. Printed materials consist chiefly of reviews of his works and reviews he wrote of others' books.
