US Civil War Maps
The latest set of maps on the BL Georeference project has been completed; these include a fascinating collection of maps from the US Civil War (many of which include some fine portraits of bewhiskered generals).
These have now been given their appropriate latitude and longitude and overlaid on Google Maps (below - scroll to the right and you will find a selection of First World War maps: perhaps we need a chronology project, too). I particularly like the map of Fort Monroe. Amazingly, even Prang's Bird's-eye view of the Seat of War has been rectified. Many thanks to all involved, particularly the volunteers who have worked on the project.
