Although most of this large collection consists of papers of Lewis's legal practice, there are important groups which relate to the furnishing and maintenance of his city and country houses and the management of his farm, to the assembling of his outstanding collections of Asian and medieval illuminated manuscripts and of Babylonian clay tablets (now at the Free Library of Philadelphia), and to institutions with which he was closely associated, such as the American Philosophical Society, the University of Pennsylvania, and the Pennsylvania Academy of Fine Arts. Many letters and papers are about business (mortgages, rents, directorships in banks and insurance companies, and investments) and about the social and cultural life of Philadelphia (operas, libraries, museums, and schools for the handicapped).

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.
