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.

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.

The Hadassah Archives documents the activities of Hadassah, the Women's Zionist Organization of America. Founded in 1912, the organization engaged hundreds of thousands of American Jewish women in the Zionist project. Materials include extensive records of its social welfare projects in Palestine and later Israel, such as Youth Aliyah and the Hadassah Medical Organization. Administrative records document the organization's governance, operations, and functions. The collection also includes the papers of Hadassah founder, Henrietta Szold, as well as the organization's national presidents, executive directors, and other important individuals. Additional materials also document Hadassah's organizational activity in the United States such as annual and midwinter conventions and the dozens of active local chapters from all over the United States. Hadassah maintained an active publishing schedule, and the records include hundreds of published newsletters, flyers, and magazines. Other materials include thousands of photographs, extensive audiovisual material, and hundreds of artifacts.

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 Medical Organization Records in the Hadassah Archives document Hadassah's work in providing health care resources in Palestine/Israel since 1918. The activities documented revolve around the development of the Hadassah Hospital; health centers; dental centers; occupational and rehabilitative services; medical, nursing, dental, and pharmacy schools; as well as numerous educative and preventive projects, especially those aimed at infant care. The documents also reflect the history of the Yishuv (Jewish settlement in Palestine) and the establishment of the State of Israel. The record group contains articles, clippings, correspondence, financial records, fundraising material, minutes, personal accounts, press releases, publicity material, reports, and statistical reports.

Lt. Col. Rachel Diane (Rae) Landy was a nursing pioneer in the development of health services in Palestine under the auspices of Hadassah from 1913-1915, and served as a U.S. Army nurse in World War I through World War II. The collection documents hospital care in Palestine and the history of Hadassah; career women in the early 20th century, particularly military personnel and profession innovators; and the Cleveland, Ohio Jewish community, school system, and George Crile U.S. Army Hospital. Documents include correspondence, reminiscences, legal documents, newspaper and magazine clippings, and photographs.

The Baron de Hirsch Fund Records document the organization's involvement in the planning of agricultural communities across the United States and to some extent in South America; the founding and administrative dealings of agricultural and trade schools; the establishment of the Jewish Agricultural Society; and the business records of the Fund itself. In addition, the collection documents the protection offered to immigrants through port work, relief, temporary aid, promotion of suburban industrial enterprises and removal from urban centers through the Industrial Removal Office, land settlement, agricultural training, and trade and general education. In this respect, the collection is of major interest for Jewish genealogists as it documents a number of individual immigrants. In addition, the collection contains documentation on the administration and organization of the fund, documentation on Jewish farming colonies such as the Jewish Agricultural Society, Woodbine Colony and Agricultural School, and documentation on the Baron de Hirsch Trade School. In addition, the collection contains blueprints and photographs of facilities.

The Industrial Removal Office was created as part of the Jewish Agricultural Society to assimilate immigrants into American society, both economically and culturally. It worked to employ all Jewish immigrants. The collection contains administrative and financial records, immigrants' removal records, and correspondence. A database has been constructed to search for persons removed by the Industrial Removal Office.

The Youth Aliyah Records in the Hadassah Archives document Hadassah's work with multiple international organizations to rescue Jewish children from continental Europe to Palestine from 1933-1945. The collection also documents Hadassah's involvement with Youth Aliyah since 1946 in providing residential, educational, vocational, rehabilitative and therapeutic care for displaced and at-risk youth from around the world.

The material in this record group was culled from Hadassah's Central Files in Israel in the early 1980s to document Hadassah's role in Zionist history. Originally formed from a Zionist women's study group, the first Hadassah chapter in New York had a strong relationship with the Zionist Organization of America (ZOA; then known as the Federation of American Zionists). The material in this record group documents Hadassah's relationship to the ZOA and to other Zionist organizations in the United States, Europe, and Palestine/Israel, particularly in the years leading up to Israeli statehood in 1948. Other subjects addressed in this record group include the founding of Hadassah; World War II, particularly relating to Jewish emigration and refugees; the founding of the United Nations and the debate over recognition of a Jewish state; the partition of Palestine; and Arab-Jewish relations. Included are articles, clippings, convention resolutions, correspondence, diary extracts, memorandums, minutes, press releases, printed ephemera, publications, reports, and speeches.
