I bought "The Country and the City" by Raymond Williams yesterday for 10 Swedish kronor (about a euro) at my local second-hand bookshop.

I've never really noticed this book before, but this 1973 critical work, republished as a Paladin paperback two years later, deals with (according to the blurb on the back):

The Country and City is a sustained and thoroughgoing attempt to relate English literature to its social background. His method is to treat the topics associated with the ancient contrast between "the Country" and "the City" as they arise in the work odf a great number of English writers from 1600 to the present day.
Williams examines the opposites, with the countryside standing for innocence and the good life, and the city for sophistication, money, luxury, corruption and, in modern times, alienation.

No, I've not read it yet, but it looks to be an interesting contrast.
