The depth and breadth of the Historical Society of Pennsylvania’s 20th-century collections is significant. These rich collections, dating up through the late 20th century, have both a regional and national scope. They document the greater Philadelphia area, national figures and organizations, as well as individuals and associations that had a nationwide impact. The experiences of diverse segments of society, including African Americans, women, and various ethnic and immigrant groups, are well represented.
This guide, though not comprehensive, is meant to showcase the extensive nature of HSP’s 20th-century holdings and help users locate collections that may be of interest to them.
Personal papers, family papers, and institutional records document various businesses and industries in Philadelphia and the surrounding region.

The Historical Society of Pennsylvania is one of the most complete and professional genealogy centers in the nation, and the largest in the Mid-Atlantic region.

The maltreatment of Japanese Americans during World War II is also documented in several significant personal and family papers.
The Historical Society holds a significant number of collections that document women’s various contributions to, and experiences during, the 20th century. In particular, the collections relate to women's contributions to politics, arts and culture, and civil society.
