The Library Company of Philadelphia is an independent research library concentrating on American society and culture from the 17th through the 19th centuries. Free and open to the public, the Library Company houses an extensive non-circulating collection of rare books, manuscripts, broadsides, ephemera, prints, photographs, and works of art. The mission of the Library Company is to preserve, interpret, make available, and augment the valuable materials within its care. We serve a diverse constituency throughout Philadelphia and the nation, offering comprehensive reader services, an internationally renowned fellowship program, online catalogs, and regular exhibitions and public programs.




The Library Company is America’s first successful lending library and oldest cultural institution. It was founded in 1731 by Benjamin Franklin as a subscription library supported by its shareholders, as it is to this day.

During the early years of the United States, books were not widely available. Standard English reference works were expensive and difficult to find: they had to be shipped to the colonies from Europe, and the average person could not afford to purchase the books that well-rounded intellectuals thought worth reading.

In 1731, Benjamin Franklin convinced members of the Junto, his “society of mutual improvement,” to pool their resources and purchase a collection of books none could have afforded individually. Articles of Agreement were drafted on July 1, 1731, and the Library Company of Philadelphia was established when 50 founding shareholders signed on. Each contributed 40 shillings and agreed to pay ten shillings per year thereafter. As the Library Company’s collection grew, the book capital of each shareholder expanded as well.

The collections grew with the nation and reflect the country’s many faces and varied interests. From the Revolutionary War to 1800, when the national government was in Philadelphia, the Library Company also served as the Library of Congress. Until the 1850s it was the largest public library in America. All of the books the Library Company acquired year by year over more than two and a half centuries are still on its shelves, along with many others added since it was transformed into a research library in the 1950s. In the 21st century, the Library Company serves as a resource for a variety of readers, from high school students to senior scholars, from novelists to film producers, and anyone else with an interest in our collections.

Public Programs


The Library Company regularly presents exhibits, lectures, symposia, conferences, gallery talks, and other programs in order to make the collections accessible to the widest possible audience. Exhibitions such as “Ben Franklin, Writer and Printer;” “Ardent Spirits: The Origins of the American Temperance Movement;” and “The Hook and the Book: the Emergence of Knitting and Crocheting in American Popular Culture” highlight various strengths of our collection in engaging ways. Program topics range widely; recent events have included a panel discussion on Philadelphia’s food history, casual open houses, the announcement of the 2007 National Book Award finalists, and numerous book release parties. Most events are free and open to the public (although reservations are often requested due to space constraints). For details on upcoming events, please see the EVENTS section of this site. Additionally, many of our EXHIBITIONS are available online.

A variety of programs are available to those unable to visit the Library Company in person. Our semi-annual newsletter (The Occasional Miscellany ) and our monthly electronic newsletter educate and inform on topics such as recent acquisitions, exhibitions, publications, and seminars, along with interesting features on our collection’s most remarkable pieces.
