The Annual and Mid-Winter National Conventions Records document the proceedings and outcomes of the conventions and conferences attended by Hadassah’s National Board as well as by convention delegates from the various regions of Hadassah. The conventions in particular are where local and regional leaders meet with each other and the National Board and learn about Hadassah’s various projects and committees. This record group also includes annual reports from 1926-2001.

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.

The records of the People's Relief Committee for Jewish War Sufferers consist of correspondence with Jewish communities and relief organizations in Europe, Palestine, Cuba, South America, the United States, and Canada; as well as scrapbooks containing U.S. and Canadian Yiddish and English newspaper clippings and printed promotional literature pertaining to the fundraising activities of the People's Relief Committee in North America and abroad.
