Historical Society Of Pennsylvania
The Society's building, designed by Addison Hutton and listed on the City of Philadelphia's Register of Historical Places, houses some 600,000 printed items and over 19 million manuscript and graphic items. The Society is one of the largest family history libraries in the nation, has preeminent printed collections on Pennsylvania and regional history, and offers superb manuscript collections renowned for their strength in 17th-, 18th-, and 19th-century history. With the addition of the holdings of The Balch Institute for Ethnic Studies in 2002 (and those of The Genealogical Society of Pennsylvania in 2006 through a Strategic Alliance Agreement), the Society has become a chief center for the documentation and study of the ethnic communities and immigrant experiences shared by people whose American history began more recently-between the late nineteenth century and our own times. Together these holdings, old and new, make the Society one of the nation's most important special collections libraries-a center of historical documentation and study, education, and engagement.
