HSP
Founded in 1824, the Historical Society of Pennsylvania (HSP) is one of the nation’s most significant archives of historical documents. Our mission is to preserve and provide access to our collection of over 23 million manuscripts, published works, photographs, and graphic materials spanning centuries of American history.
Featured Collections
As an active collecting institution, our holdings support research, learning, and exploration across a diverse range of topics, with strengths in Pennsylvania history, family and community history, ethnic history, science and technology, and the arts. Through research services, educational programs, public events, exhibits, publications, and fellowships, HSP invites you to connect with the past and engage with the stories that define our shared history.
At HSP, we invite you to Make History Yours through the vast collections of Philadelphia’s Library of American History.
Below are some examples of our treasures grouped by our five collection themes.
Pennsylvania: Crucible of the Nation
Land deeds between the Lenni Lenape people and William Penn, the first handwritten drafts of the Articles of Confederation and the United States Constitution, and clippings of George Washington’s hair that were saved by his barber are among the treasures that document the deeply entwined histories of Pennsylvania and the United States of America.
Pennsylvania Indenture

First Draft of the U.S. Constitution

What’s Your Story? Chronicling Families and Communities
Whether descended from a founding father and mother, an enslaved couple, or recent immigrants, genealogists of all background can make “aha” discoveries about their family histories by delving into HSP’s unique archives. Likewise, maps, surveys, photographs, and graphic arts enable residents to explore their homes, neighborhoods, and communities.
Holy Redeemer Basketball Players
1948—Girls playing basketball, Holy Redeemer Chinese Catholic Church
Lippincott Family Tree
Genealogical tree of the Lippincott family in America
America’s Promise and its Many Voices
The United States is a melting pot where people of all races, ethnicities, genders, and religions can achieve success. However, many have experienced a substantial gap between this ideal and reality. As they strive to overcome legal, economic, and other barriers, the voices and actions of women, people of color, immigrants from around the globe, and LGBTQ people are richly reflected in HSP’s collections.

1854—William Still's record of the Underground Railroad in Philadelphia.

1915—Suffragists' Tour Photo from the League of Women Voter records
Americans and Innovation: Science, Technology, & Enterprise
The spirit of enterprise is embedded at HSP in the first map of Philadelphia that was used by William Penn to sell plots of land, the natural history and nursery work of Mark Catesby and the Bartram Family, and the rapid development of industry exemplified by Baldwin Locomotive Works. Wanamaker's Department Store reinvented retail, creating abundant displays of new fashions amid dining venues and organ concerts, making shopping an experience for the growing middle class rather than merely the fulfillment of basic needs. Philadelphia is also a city of many firsts, including the first American photograph taken in 1839 by inventor Joseph Saxton from his vantage point in the United States Mint, just a few blocks from HSP, where it is now preserved.

The Soul of America: Visual, Performing, and Literary Arts
In the eighteenth century, Peale’s Museum was established as a popular entertainment space aimed at providing ordinary people access to science and art, and in the nineteenth century, the Academy of Music was created to rival the grandeur of European opera houses while opening such venues to wider audiences. In the twentieth century, the WPA art projects and community arts organizations, such as those led by H. August Wilson, more fully realized the democratization of arts and culture.
