But the image quality is gawdawful, what did they scan them with?
I like the map on their own whole page, which shows the whole world
but only actually offers the 50 US states and Puerto Rico.
You can finally get Canadian topo maps online
http://www.geogratis.ca/geogratis/en/product/search.do?id=10119
with much better quality (and a broadband connection and a large hard
drive) but the site navigation is bizarre and needs some patience
(okay, a lot of patience).
