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.

Hadassah Functions and Operations Records represent the bulk of aid and services provided to Hadassah's membership, from the 1920s to 2011. Materials found in the record group include correspondence, clippings, press releases, manuals and kits for chapters and members to implement programming and chapter structure, fundraising campaigns, scripts, study guides, programming for local and national meetings, biographical files, and training documentation. Departments documented in the record group include Public Affairs, Education, Women's Health, American Affairs, Zionist and International Affairs, Speakers Bureau, Fundraising, Program, Organization, Outreach and Tourism Departments. Materials related to the general administration of Hadassah are also in the record group; these materials include research and development of projects, archives department correspondence and other materials, Hadassah House administration, and strategic planning. The record group also documents Hadassah's efforts to expand membership outside of the United States, by the development of Hadassah International.

This record group contains meeting minutes, correspondence and reports of the Hadassah Council in Israel (originally the Hadassah Emergency Services and the Hadassah Council in Palestine), the Hadassah Youth Services (originally the Palestine Council of Hadassah) and the Hadassah Youth Services (HYS) successor organizations, Hadassah Vocational Education Services (HVES) and Hadassah Israel Education Services (HIES). The records represent the activities of Hadassah's representatives in Palestine/Israel, from 1927 to the 1990s. The Hadassah Youth Services focused on providing services to underserved youth in Palestine/Israel, most notably with their school luncheon and Guggenheimer playground programs. After HYS changed its working name to HVES in 1952, it began to focus on vocational education projects in Israel. Legally, however, the name of the organization in Israel remained Hadassah Youth Services. The Hadassah Council in Israel acted as an advisor and liaison between Hadassah's American offices and Hadassah's Israel projects, including the Hadassah Medical Organization, Youth Aliyah, and Hadassah Youth Services.
