I found this on there, http://www.wdl.org/en/item/49/ - British Empire Throughout the World Exhibited in One View - By John Bartholomew (1831-1893) - Amazing to think we can access stuff from the 17th Century via the web!
And a lots of stuff on America here - http://www.wdl.org/en/search/gallery?ql=en&a=-8000&b=2009&c=US&r=NorthAmerica
