Old Maps Online is an online map that you can browse and search to find historical maps to view online, to download, and to print. You can search the map by entering a location or you can just pan and zoom around the world to find historical maps. In
the video embedded below I demonstrate how to use Old Maps Online.

Applications for Education
The maps that you and your students find could be used as overlays in the Google Earth layers. You might also use the maps for a local history comparison activity by comparing your students’ current vision of where they live with what it looked like in the past.
