Our Map Collection provides researchers and explorers with more than 130,000 current and historical maps, as well as other geographical resources, covering every part of the world. The collection is especially strong in Philadelphia and Pennsylvania maps and atlases, and an extensive collection of aerial photos of the Delaware Valley provides a fascinating view of the development of our region over the past 70 years.
Featured Item
Flooding rivers may grab the headlines, but did you know that Philadelphia's streams covered but not conquered by development - continually damage our city? Underground streams unsettle homes, crack walls and soak basements - in some cases demanding the demolition of entire neighborhoods. Are there streams in your backyard? Under your business? Find out today by visiting our Map Collection. We offer historical city atlases and stream maps that will help you discover the secret waters beneath our city.
