The Hadassah subject file record group is a collection of files of organizations, events, and genre subjects originally arranged alphabetically by Hadassah’s central filing department.

This collection includes correspondence, clippings, newsletters, photographs, and other ephemeral documents.

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.
