Aaronsberg, PA (founded 1786) and Aaron Levy (1742-1815), undated, 1786, 1792

The documents in the collection were originally bound in a leather book embossed with the title "Autograph Letters and Documents Relating to American Jewish History." As of April 2023, the AJHS has not discovered how or why donated Rosenbach materials were removed and placed in the bound volume. Notes found in the collection of documents include several items that were removed for exhibitions and never returned to the book. The earliest of these notes is from 1937, indicating that the volume was created prior to that year. In 2023, the documents were removed from the bound book by the Cahnman Preservation Laboratory at the Center for Jewish History and digitized by the staff of the American Jewish Historical Society. The documents were then ingested into the Center's digital management system and are now viewable to the public.

The collection holds various documents from prominent members of Jewish society in the 18th and 19th centures, plus some advertisements and book pages. Documents relate to the American Revolution and tariffs; American Revolution pensions; politics between Whig and Democratic issues during the 1840s; other correspondence and items published from pamphlets promoting books or schools.
