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.

This collection tells the story of Liselotte (Lilo) Thekla Lamm, her parents Leo Lamm and Margarete (Gretel) Lamm née Falk, husbands Norbert Goldenberg, Hans Gerhard Ollendorff, and William (Bill) Thurnauer, their children and grandchildren, and members of their extended families. The families’ lives in Germany, immigration to the United States, and professional, political and philanthropic activities are documented through vital documents, photographs, correspondence, writings, articles, and clippings.

The collection contains the papers of Shalom Schwarzbard (1886-1938), the Russian-born French Jewish watchmaker, revolutionary, writer and activist for Jewish self-defense. In May 1926 in Paris, Schwarzbard assassinated the exiled Ukrainian nationalist leader Simon Petlyura, whom he held responsible for the pogroms against the Jews in the Ukraine in 1918-1921. His trial in October 1927, at which he was acquitted, drew worldwide attention. The collection consists of correspondence, manuscripts of Shalom Schwarzbard's autobiographical writings, personal documents, clippings, and printed ephemera, as well as poems by Schwarzbard's wife Anna and others. Materials in this collection mostly relate to Shalom Schwarzbard's writings, his speaking engagements following his acquittal, and his efforts in the 1930s to organize Jewish war veterans and war victims of the First World War.
