The U.S. Geological Survey has an historical map browser here:
http://historicalmaps.arcgis.com/usgs/
Click an area on the map or type in the name of a location, and the server will display a list of archived maps covering that area in a ribbon along the bottom of the page. Click one and it will be superimposed on the modern map. You can adjust the transparency of the historic map to compare features, or download a high-res PDF as a ZIP file for use on your own computer.
I haven't found any maps that go back before the 1880s, but still this is a very useful tool to see how a given location has changed over the years.
Enjoy!
