::::ISBN number is the best if you have it. Mediawiki has magic so that if you just say ISBN 012345689 (with the correct nubmer of digits, I think either 9 or 12, depending) it creates a link to a generic (non vendor specific) page where interested readers can pursue the matter further. See Wikipedia:ISBN.  (To find ISBN's: A search via Google on the title and ISBN usually although not always works.) ++: /
