Really scraping the barrel now Keith if you reckon Amazon is not a bookshop. Dunno about anyone else but I get all my books (yes and lots of other things) from there now. Still, if you insist. Is Waterstones not a bookshop either? Anyway. I have mentioned 2 historians who disagree with you and you keep evading the issue. They are historians. They are alive. They disagree with you. What other criteria should they meet?
