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.

This record group contains materials related to the local units of Hadassah—groups, chapters, regions, and co-ops—as well as Junior Hadassah, a youth organization that functioned as a group within the Hadassah Chapter structure. The record group documents over one hundred years of Hadassah’s growth, and illuminates a century of American Jewish communal life, particularly that of Jewish women, across the United States. The record group reflects the formation, administration and activities of the individual groups, chapters, co-ops and regions, and contains information on local events and programs organized around fundraising, Zionism, Jewish heritage, religion and holidays celebration, the study of Hebrew and Yiddish, women's issues, fashion, health, technology and many other topics.

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.
