Its collections also cover pre-migration from Europe, the genealogical “stepping stones” across the Caribbean, and out-migration to Canada. Its collection includes 600,000 printed items and more than 21 million manuscript and graphic items. It 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. By acquiring the holdings of The Balch Institute for Ethnic Studies in 2002 and those of The Genealogical Society of Pennsylvania in 2006, the Society has become a chief center for the documentation and study of the ethnic communities and immigrant experiences between the late 19th century century and our own times.
