Under "England", 'Language' and 'Joyful Molly' are a single link.

I'm very fond of Greenwood's Map of London 1827 (http://users.bathspa.ac.uk/greenwood/) and Map of John Snow's London in 1859 (http://www.ph.ucla.edu/epi/snow/1859map/map1859.html), which I don't see on your list of maps.

I have swacks of links for period research, here at del.icio.us (http://del.icio.us/Adventurat/research), which you're welcome to browse for new and useful tidbits!
