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.
