The Records of the Board of Delegates of American Israelites (1859-1878) documents the life cycle of the Board of Delegates, a Jewish civil rights organization located in New York City. The Board served in a two-fold function: acting as a central organization for American Jews and working on behalf of Jews abroad. To the latter end, the Delegates collaborated with the Committee of Deputies of British Jews and the French Alliance Israélite Universelle to provide for the relief and aid, civil, and religious rights of Jews throughout the Americas, Europe, North Africa, and the Middle East, particularly Romania, Ottoman Palestine including Jerusalem, and Morocco.

In the U.S., the Delegates were partially responsible for the appointment of the first Jewish Military Chaplain and surveyed member synagogues concerning the history and size of their congregation, the first organization to systematically record this type of information in the States. The Delegates merged with the Union of American Hebrew Congregations (UAHC) in 1878 and dissolved in 1925. Correspondents include Adolph Crémieux, Sir Moses Montefiore, Benjamin Franklin Peixotto, Isaacs S. Myer, the Rev. Dr. Arnold Fischel, and Maj. General Benjamin Butler. Documents include correspondence, minutes, committee reports, memorials, announcements, surveys, some printed material including clippings, and a 1932 Rabbinical thesis on the Delegates by Allan Tarshish.

Morris U. Schappes, self-taught historian of American Jewish History, author, teacher, and editor of Jewish Currents for 40 years, is also known as a victim of hearings conducted in 1941 by the Rapp-Coudert Committee, a New York legislative committee investigating Communist activities in the state educational system.

This collection is comprised of materials related to the Rapp-Coudert proceedings and Schappes' subsequent imprisonment, and of materials generated in the following decades. Topics represented include academic freedom, Communism in the U.S., the roles of Jews in U.S. history, and Emma Lazarus. The formats primarily present in the collection are research notes, manuscripts, clippings, and correspondence.

University professor, historian, and scholar Oscar I. Janowsky sought to understand Jewish culture and human rights in light of modern anti-Semitism, imperialism, and pluralistic states. Throughout his robust career he was a professor of history at the City College of New York, he also served as an advisor to League of Nations High Commissioner James G. McDonald, directed and authored major studies in the fields of Jewish community centers and education. The papers in this collection include his correspondence with colleagues and friends, research notes and article drafts, and his unpublished memoirs.
