I found a site with wonderful old maps by David Rumsey on John Udell's weblog.
David Rumsey is a philanthropist who collects historical maps, scans them at high resolution, and publishes them on the Internet as open content that anyone can access and repurpose.
A good write-up of David's talk at a recent conference is here.
Note when using the web interface to browse and display the maps: you need to disable popup-blocking for the site and you need to double-click the maps to open them.
Great great great (time sink...)
