Sir Walter Scott - Letters on Demonology and Witchcraft

Which reads well, and points you off in a thousand other directions - excellent sources and references. Scott could write - although a little out of fashion, and his take on the paranormal is done with all the credulity the age of reason could afford - more reason and compassion 200 years ago than you'll find now by a long shot now anywhere in the world. I liked, but it's an idiosyncratic little read, the pinch of salt that should be taken with Aleister Crowley and Montague Summers.
