The Lipsky Family Papers reflect the professional and personal activities of Eleazar Lipsky (1911-1993), his father, Zionist leader Louis Lipsky (1876-1963), and his mother, Charlotte Lipsky (1879-1959), as well as other family members. Eleazar Lipsky was a lawyer, novelist, Zionist and the head of the Jewish Telegraphic Agency in the early 1960s. While working on a multi-part family novel, Eleazar Lipsky gathered and arranged much of the family material in this collection. In addition to family history, the collection contains information on the American Zionist movement, Bernard Richards’s role in the Committee of Jewish Delegations at the 1919 Paris Peace Conference, and various legal battles involving such parties as the Jewish Week, the American Examiner, Doubleday, Philip Hochstein and Lillie Shultz. The materials include correspondence, an unfinished manuscript, legal transcripts, clippings, speeches, research materials, financial documents, miscellaneous writings and a few photographs.

This collection contains the personal and professional papers of William Edlin, editor of The Day and a prominent Socialist. It includes correspondence with individuals and with organizations, newspaper clippings, manuscripts of works by Edlin and by others as well as translations done by Edlin, and some of Edlin’s personal documents. These materials relate to Edlin’s involvement with The Day, with the Socialist Party, the Workmen’s Circle, various labor and Zionist organizations, literary clubs and activities, and with music, art and drama.

The collection represents the papers of Morris David Waldman (1879-1963), a rabbi, social worker and communal leader, who was appointed executive secretary of one of the main Jewish defense organizations, the American Jewish Committee (AJC), in 1928. The executive secretary had top executive function at the organization and was in charge of working out and implementing the organization’s projects and policies regarding monitoring the civil and human rights of the Jews, and intervening on behalf of the Jews both in the U.S. and abroad. In 1942, Waldman was promoted to executive vice-president, a position he held until his retirement in 1945. The Morris Waldman Files relate to all of Waldman's activities as acting executive secretary and vice-president of the AJC.

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 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.
