This collection of letters, while tiny, is actually quite rich in content. Cadwalader wrote to Samuel Meredith, a politician and fellow Revolutionary War soldier, concerning the war, his real estate holdings in Philadelphia, and the local political climate. The seven items are dated from October 5, 1779 to March 9, 1798, during which Cadwalader served in the military, reentered politics, got married, and then retired from public service.

An additional item is a memorial volume (ca. 150 pp.), including a family genealogy and land surveys in watercolor (B Sa95f).

This collection includes letters, diaries, notebooks, and early photographs, relating primarily to the Wister family of Germantown and Philadelphia. Much of the correspondence concerns domestic news and consists of letters from or to Sarah Wister. These include interesting observations on Germantown and Philadelphia society from other families as well, such as the Bayntons and Bullocks. There are numerous letters from various Wisters, including Casper, Charles Jones, Elizabeth (including a journal of a trip to Bristol, 1783), Hannah, John, Owen Jones, and others. There is also poetry by Sarah.

The collection contains information on Fox family speculation in western lands, two manuscript maps from the 1790's and 1830's depicting the family's holdings in northwestern Pennsylvania, and a photograph album from the 1890's documenting Chestnutwold, the Fox estate adjacent to Andalusia. Chief correspondents are Samuel and George Fox.

The son of William Franklin, Royal Governor of New Jersey, William Temple Franklin worked as aide to his grandfather, Benjamin Franklin, when the latter served as minister to France during the American Revolution. A bonvivant, Temple received his highest public appointment as Secretary to the American delegation at the Treaty of Versailles in 1782-1783, largely through the influence of his famous grandfather, but never again attained a significant post. As Franklin's literary heir, he edited and published a three volume set of his grandfather's writings in 1817. He married his long time mistress a few months before his death in Paris in 1823. The William Temple Franklin Papers provides a richly detailed portrait of the life of the grandson of Benjamin Franklin, and consists largely of letters received during the years that Temple served as his grandfather's aide in France, 1776-1785. Although much of the correspondence is routine, during this period, Temple received regular reports from friends and diplomatic colleagues relaying information on the American Revolution, the course of diplomatic and peace negotiations, and French public opinion on Benjamin Franklin and the new United States. The collection is also a rich resource for information on the personal lives of the Franklins, including interesting correspondence from Temple's relatives William Franklin, Elizabeth Franklin, Sarah Franklin Bache, and Jonathan Williams, and his mistress Blanchette Caillot.

George Clymer was a successful merchant, well-known politician, and a generous philanthropist, but is today most famous for being a signer of the Declaration of Independence. As a proponent of independence, he joined various local political committees including six of the seven Philadelphia resistance committees. From there, he entered the national political arena and in 1776 was elected to the Second Continental Congress where he signed the Declaration of Independence. The George Clymer Collection is a small one and not reflective of his varied pursuits. There are twenty-seven documents, most of which are not signed by Clymer; those that are signed by Clymer are dated between May 3, 1800 and January 22, 1813. The items represent not Clymer's political activities but his ordinary legal and real estate transactions.

James Burd (1726-1793) was well-known in colonial Pennsylvania through his role in the French and Indian War, as well as his connections to many of the colony's leading families (most notably the Shippen family). Initially starting out as a merchant in Philadelphia, Burd became increasingly involved with colonial affairs after moving to Lancaster County with his family in 1752. It would be on the frontier where Burd would make his mark first as a soldier, and later as a magistrate. The Burd-Shippen Papers consist mainly of letters and business documents sent to James Burd, with the bulk of the collection relating to the French and Indian War, 1754-1763, in which Burd served as an officer commanding troops at Fort Augusta and elsewhere. The collection reflects all aspects of Burd's life in Pennsylvania as a merchant, soldier, and magistrate; as well as his involvement with the Shippen family professionally and personally. Intermixed with items sent to Burd are receipts to his wife Sarah Shippen Burd, and correspondence between Edward Shippen and James Hamilton regarding land matters and Indian affairs in Lancaster.

The Calendar of the Papers of Benjamin Franklin prepared by Isaac Minis Hays for the bicentennial of Franklin's birth in 1906 provides access to the largest portion of the Franklin Papers at the APS. The items were originally bound into volumes in roughly chronological order, with letters to Franklin preceding those from Franklin and at the end of the collection, Franklin's letters owned by the University of Pennsylvania. Each manuscript is still identified by Hays' reference numbers, which include a roman numeral refering to the original volume followed by an arabic number to identify the folio. The electronic version of the finding aid replicates Hays' calendar, including the introductory material and item-level descriptions. It has been updated to reflect corrections in the metadata, corrections of personal names, dates, and description.

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.
