ISBN13 support

LGN · 11-08-2010, 01:48 AM

When I enter a book with ISBN13 it gives invalid and a red input field untill I remove the first 3 numbers to (hopefully) add a ISBN10.

Is there a setting that supports ISBN13?

There are no setting changes for it to work

Are those first 3 numbers 978 or 979? (those are the EAN number ranges reserved for books).

A Red condition indicates a Check Digit (the 13th last digit) calculation mismatch.
Numbers Only (no I, l or O allowed

)

Publishers have been known to make printing/calculation (bar code) errors.
While I have not seen it done on books, I have seen "made up" EAN numbers on food goods imported to the USA..

All I've ever entered are ISBN 13 numbers and have never had a problem, no special setting required.

your ISBN 13 number is invalid, it was created by someone that prefixed 978 to an ISBN10 without recalculating the check bit.

Thanks for the answers. At least I know what causes the issue.
