Containing over 4 linear feet of letters and documents, the Franklin-Bache Papers comprises the second largest collection of letters and documents relating to Benjamin Franklin in the APS Library. Although the scope of the collection is broad, including materials from the time of Franklin's arrival in Philadelphia to his death, the heart of the collection documents the period of Franklin's ministry in France (1776-1785) and his diplomatic efforts to win financial and military support for the revolutionary cause, as well as less intensive coverage of his ministry in England before the Revolution. Franklin's correspondence with American and French officials, financiers (personal and otherwise), and savants provides tantalizing details on the social context of Franklin's ministry in France, his intellectual life, and his growing celebrity. Much of the correspondence documents the efforts to convince French officials early in the war to support the American cause, but there is valuable material relating to the peace negotiations as well. The collection is equally rich in personal correspondence, including a rich set of letters from Mary Stevenson Hewson, Georgiana Shipley, Catherine Ray Greene, Jane Mecom, Deborah Franklin, and a number of Franklin's other relatives. The collection is arranged chronologically.

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.
