A Vision of Britain Through Time

While trying to find various maps of the western environs of London to get my bearings in the scene I'm writing in my wip I came across this super-looking resource: a Vision of Britain Through Time.

Typing in my home postcode I found out immediately that 8,773 people lived in St Albans in 1801. Now it's 128,000.

As well as historical census information, there are maps and historical descriptions.

Unfortunately I'm off to London shortly to visit the Persian exhbition at the British Museum so I'll have to play with this website more tomorrow...
