Over 3,000 (primarily) 19thc maps in books from the British Library collections have been extracted from the scanned volumes and are available online for georeferencing and overlaying. The images are public domain and may be downloaded from Flickr (jpeg), and the overlays (kml) and coordinate data (wld) from BL Georeferencer. Release to the public for crowdsourced georeferencing opened this morning at http://www.bl.uk/maps/ Maps placed today - a mere 3% - can be perused geographically here - a nice global scattering! http://www.bl.uk/maps/georeferencingmap.html Kimberly C.
