The edit metadata ISBN returned a totally different book but the cover of the book I was adding had ISBN number printed on it.
Any format for the result would be good. CSV copiable to clipboard seems kind of familiar.
An indicator such as an * at the end of each book to determine whether it is an exact match or fuzzy might be of some help as well.
I have been meaning to do something like this in excel with a catalogue but haven't got around to it yet.

That is not supposed to happen (but can. Printing error.).
The first digit of an ISBN is the Language- then Publisher- then book_number- the a Mod11 check digit
The total length is always 10 digits (the check digit can be "X")
the language is 1 digit
The check digit is always 1 char
the publisher can be from 1 to 7 digits,
the book number is whats left over (a 7 digit pub, hasa sigle digit for books="really small press
)
So, was you "duplicate ISBN from the same publisher?
(it is not uncommon to see EAN numbers that have been "made up" rather than pay the fee for a manufacturers number group
)
