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.

The materials in the record group mostly consist of reproductions of building plans of the Hadassah hospitals on Mount Scopus and Ein Kerem from the 1920s to the 2000s. Other properties documented in the record group include buildings managed by Youth Aliyah, Hadassah Youth Services, Young Judaea, Hadassah Israel Education Services, the National Office, and the Hadassah Medical Organization. These records document a core Hadassah function, the building of medical and social service facilities in Palestine/Israel.

This record group contains three-dimensional objects and printed materials that relate to the history of Hadassah. A bulk of this record group consists of promotional and commemorative objects and awards created by Hadassah for its Annual and Midwinter National Conventions, and for Young Judaea events. Examples of such items include t-shirts, hats, bags, buttons, stationery and keychains. Artifacts created by local Hadassah chapters and regions, as well as awards received by local and national Hadassah leaders from other organizations, are also included. Of a particular interest is the bronze death mask of Henrietta Szold.

This record group is made up of mostly audio and moving images materials, including ¼-inch open audio reels, 16mm film, filmstrips, cassette tapes, VHS tapes, CDs, DVDs, LPs, 3.5 inch floppy disks, and other media, dating from the 1920s up to 2010. The films and audio recordings document Hadassah's efforts to publicize themselves to their members and those outside of Hadassah, by raising awareness of their history, fundraising efforts, and projects in United States and Israel, especially the Hadassah Medical Organization and Youth Aliyah projects and programs. Hadassah also used recordings to document important proceedings, including departmental and board meetings, Midwinter Conferences, and National Conventions.

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 subject file record group is a collection of files of organizations, events, and genre subjects originally arranged alphabetically by Hadassah’s central filing department. These files served and serve as a ready reference source that represents both the direct and indirect involvement of Hadassah in both national and international affairs. This collection includes correspondence, clippings, newsletters, photographs, and other ephemeral documents.

The Jewish National Fund records reflect the non-profit organization’s afforestation efforts in Israel in funding partnership with Hadassah. Included in this collection are personnel records, membership lists, and convention summaries, as well as correspondence, project documentation, and publications such as press releases, and magazines.

The Name File record group is a collection of documents representing various individuals, corporations, and non-profit groups who were affiliated with Hadassah. These files were originally arranged alphabetically by the organization's central filing department as a ready reference source on leaders, doctors, speakers, donors, and religious figures associated with Hadassah's many projects. This collection includes correspondence, clippings, newsletters, and other ephemeral documents.

This record group contains personal papers and special collections documenting individuals, both Hadassah members and non-Hadassah members, who were important to Hadassah. Much of the material forming the collections in this record group came from the administrative files of the national office of Hadassah, though some of the material was donated to Hadassah. Key individuals represented within this record group include Hadassah national board members Anna Tulin Elyachar, Bertha S. Schoolman, and Denise Tourover Ezekiel, as well as Jesse Zel Lurie who served as the first professional editor of Hadassah Magazine (originally Hadassah Newsletter) from 1947 to 1980.

The materials in this record group document the entirety of Hadassah’s history and work in Israel and the United States in photographs—prints, slides, glass lantern plates, and digital images.

Young Judaea is the oldest Zionist youth organization in the United States, established as a national organization in 1909 by the Federation of American Zionists. It was supported by Hadassah, including direct financial sponsorship from 1967-2011. The major aims of Young Judaea throughout its history have been to advance the cause of Zionism, to further the mental, moral, and physical development of Jewish youth, and to promote Jewish culture and ideals in accordance with Jewish traditions. Young Judaea has remained non-partisan and non-denominational, embracing and recruiting Jewish youth from all backgrounds.

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.
