Funnily enough there was an Q/A article in The Newstatesman the other week with Alan Garner, on the two latest books that have influenced him they were, Richard Bradley's - Archaeology of Natural Places, and Jay Appleton's - The Experience of Landscape. This last book is written by a geographer (and very expensive) in the 1970s.
