This collection of mainly anti-Semitic material was compiled by a Jewish librarian of German descent who infiltrated the pro-Nazi community developing in New York City in the years leading up to World War II. The bulk of the collection consists of publications and printed matter, with the notable exception of narrative reports that describe first-hand experiences and observations of Nazi-affiliated events. Document types include advertisements, event announcements, books, clippings, correspondence, magazines and newspapers, travel guides, political memorabilia, and other print ephemera.

Contains the Bulletin of the Jewish Center of Williamsbridge from the 1940s to the 1970s and gift books bound with yearbooks of the Center bound inside. Also includes material regarding Doctor Rabbi Akiba Predmesky (d. 1998), who served the Jewish community and the Jewish Center of Williamsbridge for over fifty years.

Contains the memoirs and scrapbooks of Bluestone, concerning his numerous communal activities, especially those in the Zionist movement. A description of the collection was published by Hyman B. Grinstein in Publications of the American Jewish Historical Society, no. 35 (1939), and a detailed inventory was prepared by Harry Bluestone (n.d.).

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.
