America250: Changing Landscapes Materials

These are materials from the collections of the State library of Pennsylvania digitized as part of the State Library's contribution to the America250 celebration. Most of the materials are newly-digitized items, now freely available to the public for the first time. Visit the individual America250 theme pages on this site to view all utilized digitized materials, both newly-digitized by the State Library of Pennsylvania and other materials held by the State Library of Pennsylvania but already freely-available.

The maps and pictures presented here illustrate the differences between the America of Colonial times and the early republic and today's United States, highlighting the different political boundaries, population sizes, modes and difficulties of travel, and built environments.
