There is an immediate problem for anyone producing a guide to places in Scotland with literary connections: as Walter Scott wrote in Marmion, ‘Nor hill, nor brook we paced along/ But had its legend or its song.’ Many years ago when the Scottish Borders was marketing itself as the ‘Land of Creativity’ I assembled a database of references which stretched to well over 1,000 entries — for example, the village of Yetholm crops up in a strange extended simile in Malcolm Lowry’s posthumous October Ferry to Gabriola.
