The records document the Histadruth Ivrit's early history to the present, representing a significant portion of its work in spreading the Hebrew language in the United States in the second half of the twentieth-century. The records include substantial amount of material regarding the organization's history, administration, public events, publications, and reports. Some information of the early history of the Histadruth Ivrit could be found in the records kept by the writer Daniel Persky. Persky collected personal and professional records that include correspondence with friends, readers, and writers; a partial collection of the drafts of his own publications, and a collection of photographs and newspaper clippings. The functions and activities of the Histadruth Ivrit are documented through Board of Trustees and Board meetings agendas and minutes; various programs for events, conventions, conferences, and celebrations; documents related to fundraising; public relations, press releases and brochures; correspondence with different individuals, organizations, and foundations; Histadruth Ivrit's publications among them the newspaper Hadoar and Tov Lichtov; a large collection of photographs, and scrapbooks. The records of the Histadruth Ivrit represent the large majority of the organization's activities dating from the 1980s to the present. Records for the earlier years of activities are fragmented and incomplete. The records related to the life of Daniel Persky are also partial and copies of many of his publications are missing. This collection included brochures, correspondence, financial records, flyers, grant applications, invitations, lists, minutes, news clipping, orders, periodicals, photographs, press releases, reports, and scrapbooks.

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.
