2,000 Historical Maps

Over the last couple of years the British Library has been busy georeferencing its collection of historical maps. So far 2,236 historical maps around the world have been added to the British Library Map Finder.

The Map Finder uses Google Maps to show the location of all the maps georeferenced so far. It allows you to search the historical maps by location and view the maps overlaid on top of Google Maps.

An opacity control allows users to compare the historical map to the current Google Map and there is even an option to view the historical map using the Google Earth browser plugin.
