11. Collecting files, 1951-2002

Materials documenting purchases of collection materials, including correspondence, invoices, and receipts. Some subseries contain a significant amount of correspondence dedicated to identifying dealers and other collectors of Judaica items. Correspondence and invoices are in English, German, and Hebrew, and originate from dealers, galleries, and shops across Europe, North America, and the Middle East. Materials are organized alphabetically by the dealer's last name. Individual items are organized within each folder in chronological order, with undated materials at the end.
