Jane Aitken (1764-1832) is a significant historical figure for several reasons. One of the first American female printers, Jane Aitken was also a bookseller, bookbinder, businesswoman, and employer during the early nineteenth century, a time when the independence of women was actively discouraged. There is a dearth of personal information about Jane Aitken, an unfortunate fact that is reflected in her surviving papers. This small collection, 145 items, is representative of her severely compromised financial situation and her constant failed efforts to rectify the situation. Her correspondence consists primarily of appeals to John Vaughan, a member and librarian of the American Philosophical Society, for loans. Vaughan was evidently a reliable and sympathetic supporter.

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.
