Heh, ok - didn't notice that. Presume that they had actually meant to give two slightly different ISBN's, such as for two different editions of the same book.
two diferent editions of the same book always have a different ISBN number.
the ISBN number is meant to distinguish among different book in commerce. Since commercially two different editions of the same book are a different thing, they have a different ISBN.
Right, what I was trying to get at, was that an editor might want to do something like this:
* Bill Smith: Green grapes (ISBN 123456789, 1457589 and 131456032) to indicate three different possible ISBN's for the same book. You'd need to manually link (or repeat the word ISBN) to make those second two actually link.
Btw someone asked about other magic words like ISBN's - patent numbers might be an example.
The hypens are use to separate the different parts of the number (language, editor, book_id, checksum). The fild dimensions are not fixed. By the way since the last digit may also be an X (the checksum is done module 11), it is not strictly a number.
Oh, cool.
