The collection consists primarily of correspondence reflecting Calmenson’s involvement in numerous national and local Jewish organizations. The largest quantity of materials is in relation to his work with the United Palestine Appeal (1926-1945, primarily 1926-1929), and the Zionist Organization of America (1919-1952). Among the local St. Paul Jewish organizations, the largest quantity of materials relates to the Emergency Committee for Palestine (1942-1951), and the Zionist Organization of America, St. Paul Chapter (1918-1950). Among his correspondents are Harry S. Truman, H.V. Kaltenborn, and Emanuel Neumann. Among the topics dealt with are the 1929 riots in Palestine, the protest against the Passfield paper, and the establishment of a Jewish army after World War I. The collection also contains materials relating to Calmenson’s private activities, and miscellaneous writings and papers belonging to the Calmenson family.

The Baron de Hirsch Fund Records document the organization's involvement in the planning of agricultural communities across the United States and to some extent in South America; the founding and administrative dealings of agricultural and trade schools; the establishment of the Jewish Agricultural Society; and the business records of the Fund itself. In addition, the collection documents the protection offered to immigrants through port work, relief, temporary aid, promotion of suburban industrial enterprises and removal from urban centers through the Industrial Removal Office, land settlement, agricultural training, and trade and general education. In this respect, the collection is of major interest for Jewish genealogists as it documents a number of individual immigrants. In addition, the collection contains documentation on the administration and organization of the fund, documentation on Jewish farming colonies such as the Jewish Agricultural Society, Woodbine Colony and Agricultural School, and documentation on the Baron de Hirsch Trade School. In addition, the collection contains blueprints and photographs of facilities.
