Common Knowledge, places field

I'd like to be able to browse books based in different parts of London and for that reason I might start adding places in the CK field of any books I've read which mention London. It'd be great if any of you would like to join in - the more people do it, the more easily we could look up books which feature our favourite parts of the capital (personally I have a soft spot for Camden and Kentish Town, Chalk Farm, and Hampstead Heath, because I grew up in the area).
