This is the EAN for a paperback edition of Sourcerer (a novel of Discworld) by Terry Pratchett. It's encoded in a barcode. The ISBN is 0-06-102067-2 - embedded in the EAN, except the EAN has its own checksum.
Uniform Product Code and its international relation EAN are the sort of barcode found on many products. They are 8 or 13 digit codes which include subcodes for different countries and a check digit. Books are from the country "ISBN" and periodicals from "ISSN" with a different check digit than the one for ISBNs. I think I heard that this will change soon, as ISBNs get longer. Is that correct? Business::ISBN. Do we need to add yet another module? Can we strip the country code and add the correct check digit? Thank you for your work. I am keen to examine this change.
