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 includes documents created and maintained by the Office of the President, the Office of the Executive Director and the Chair of the Division Coordinators/Directors Committee. Prominent is the Henrietta Szold series, containing correspondence by and to Szold as well as printed materials written by and about her. The files in this record group were created by a national president or executive director, or for their use, or maintained in their office during their years in office. Included are correspondence, minutes, memos, publications, reports and subject files on topics with which these individuals were involved.

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.

The Hadassah Microfilm Collection consists of 16mm and 35mm reels containing images of various Hadassah publications, administrative documents, and personal archival material.

Other than the newsletter/magazine run, all images are unique within the collection.

Interviewees include notable members of Hadassah’s National Board, the Honorary Council, Hadassah Medical Organization (HMO), Youth Aliyah, Machon Szold, and Hebrew University, among others.
