The James S. and Frances M. Bradford Collection contains a wealth of letters to and from Polly Stevenson Hewson, intimate friend of Benjamin Franklin. At the heart of the collection are approximately 40 letters from Mary Stevenson to Franklin with a smaller number in return. Friendly, increasingly intimate, these provide a glimpse of the domestic life of Franklin and his warm personal relations with the Stevensons and Hewsons. Among the noteworthy individual items is the manuscript "Craven Street Gazette" (Sept. 22-26, 1770), the mock newspaper Franklin produced while in London. The collection also contains a series of unrelated miscellaneous manuscripts that includes correspondence from William Bradford, Patrick Henry, and George Washington.

The only son of Benjamin Franklin, William Franklin served as Royal Governor of New Jersey during the critical years between 1762 and 1776. An ardent Loyalist, William split with his father over their political differences in the early days of the Revolution, and after enduring two years of imprisonment, became a leader in the Loyalist cause. He settled in London in 1782, where he worked as an agent for Loyalist claims. The William Franklin Papers are a miscellaneous assemblage of letters and documents, dealing largely with Franklin's years as Royal Governor of New Jersey. The majority of the letters are perfunctory, however they provide some information on Franklin's land holdings in New Jersey and the Ohio country. The collection includes two letters relating to Franklin's imprisonment in Connecticut during the Revolution, two affectionate letters to his sister Sarah, and one to his son William Temple Franklin.

An important 18th century radical republican theorist and political writer, Thomas Paine was a leading figure in the American Revolution. Despite his humble beginnings and lack of formal education, his reasoned and persuasive writings not only influenced nascent American republican ideology, but profoundly affected the perception of government in England and France as well. His three most influential works are Common Sense (1776), The Rights of Man (1791-1792), and The Age of Reason (1794, 1795, 1807). The Richard Gimbel Collection is a heterogeneous mix of items connected only by the fact that they were all collected by Gimbel (1898-1970) and that most were written by, to, or about the revolutionary Paine. Of primary importance are the approximately sixty-five letters or manuscripts in Paine's own hand, including Paine's 1776 manuscript notes for Common Sense, his letter of January 10, 1781, in which he takes leave of his former commanding officer, Nathanael Greene, and his January 6, 1789 letter to Kitty Nicholson Few, in which he writes of his view of matrimony and other personal matters. The collection includes a series of correspondence between Thomas Paine and Samuel Adams, which were originally marked "forgeries," these appear instead simply to be the letters of two men bearing famous names.

These letters and papers include ten small volumes of letterbooks (1752-1781), and ca. 100 pieces of correspondence with Joseph Shippen (1750-1778). Topics discussed are business in Philadelphia and Lancaster, provincial politics, army supply in the French and Indian War, land purchases and speculation, housebuilding, and family affairs.

In addition to family and business correspondence, the Charles Nicoll Bancker Family Papers contains various documents, such as a furniture inventory volume (30pp.); a Daybook, 1795-1800 (120pp.); and a very interesting journal (unidentified, but by one of the Banckers, and filed under "Description of a trip..."), from New York to Albany and back, between July 20-Aug. 15, 1793 (1 vol., 31 pp.). It contains detailed observations of the Hudson River and the towns along the way. Bancker was involved in business and trade prior to 1826, and in insurance after that date, so there is material relating to those topics in this collection. He owned a substantial library of the period, which was used by Charles Wilkes's Expedition after 1837 (see Reynell Coates to Bancker). This library, along with Bancker's notable scientific instrument collection, was sold after his death and there are published auction catalogues in the collection. There is much family correspondence from: Anne E. Bancker, Charles Gerard Bancker, Evert Bancker, Sarah U. Bancker, Violetta Bancker Talbot, Elizabeth Bancker Teackle, and John Teackle.

A collection of business and personal papers of three generations of the prominent Philadelphia Jewish family from 1750-1974. Business records include trade and land transactions (some in Yiddish) of the Gratz brothers, Barnard and Michael (1750-1804) with the business continued by Michael's sons: Simon, Hyman, Joseph, Jacob, and Benjamin (1791-1861). Personal correspondence are primarily letters to Rebecca Gratz from her sisters Rachel and Sarah (1795-1867) with later correspondence to Rachel's children: Horace and Sara Moses (1832-1879). Contains a small group of French letters related to Napoleon III, collected by family member Miriam Fox, and some heirloom artifacts.
