Genealogy at the State Library of Pennsylvania

A guide to resources available to genealogy and family history researchers through the State Library of Pennsylvania.

Maps and Geographical Information

Geographical maps and information can help the researcher locate specific individuals as well as discover locations both in the United States and throughout the world that have either ceased to exist by name, have changed names, or have become parts of different governmental entities. Geographical genealogy can be as important as knowing an ancestor's name. Historical and military maps and atlases will help clarify where records are now located that may be of value.
