Roger, I don't think I've ever seen anything like what you describe. (I always assumed the 'I' in 'ISBN' really meant "international!") Is this fairly common outside the US? MARC records let you repeat the ISBN tag. Koha doesn't. Stephen Roger Horne said: <snip>
Purely out of interest, what are Koha and other systems meant to do with a book that lists on its back cover separate ISBNs for different countries eg "An Introduction to the History of Printing Types", Dowding, The British Library & Oak Knoll Press, has "0712345779 (UK) and 1884718434 (US)" printed on the outside.
