[Maps-l] NYPL old maps tool

[Maarten Dammers]

Hi guys,

I'm at the New York Public Library right now. They showed me 
http://maps.nypl.org/warper/ . It's a very cool tool to make overlays of 
old maps on OSM. It's build using open layers. Maybe we could do 
something like this for the maps we have at Commons?
