Kew has the National Archives and a good majority of the Admirality Documents. They also have pamplets, tracts, newspapers, and other goodies. And I heard there's a nice garden to walk around in, too. ;)

Oooh, what did you go to grad school for? I'll only be here for the fall semester, but I might come back for a PhD.

Right now, I am just in the research stage, but with the historiography, I suppose I am actually kinda writing it, which is cool.
