I think it is better to do the processing at the time of rendering the page and display both the ISBNs. We already do it when indexing in the database and search engine. So if you search with ISBN 10 for an edition having only ISBN 13, it gets the right thing. For example: http://openlibrary.org/search.json?isbn=0-9844425-7-X http://openlibrary.org/api/books?bibkeys=0-9844425-7-X I think we should do that conversion on the fly when displaying the edition page.

It says: ISBN 3-518-06868-7900 Without '900' it’s an ISBN-10 I suppose and that’s how I catalogued it. My guess is that '3-518-06868-7-900' would be the ISBN-13 but I’m not sure about that. So I wanted to ask before entering that number into the database. Is that a known notation for both ISBN-10 and ISBN-13 at the same time? '3-518-06868-7-900' is not an ISBN-13. Every ISBN-13 starts with one of the prefixes 978 or 979. http://www.isbn.org/about_ISBN_standard You can validate and convert ISBN-10 to ISBN-13 here: http://www.isbn.org/ISBN_converter Best, Luciano xan. ___ Ol-discuss mailing list - Ol-discuss@archive.org http://mail.archive.org/cgi-bin/mailman/listinfo/ol-discuss Archives: http://www.mail-archive.com/ol-discuss@archive.org/ To unsubscribe from this mailing list, send email to ol-discuss-unsubscr...@archive.org -- Luciano Ramalho Twitter: @ramalhoorg Professor em: http://python.pro.br Twitter: @pythonprobr ___ Ol-discuss mailing list - Ol-discuss@archive.org http://mail.archive.org/cgi-bin/mailman/listinfo/ol-discuss Archives: http://www.mail-archive.com/ol-discuss@archive.org/ To unsubscribe from this mailing list, send email to ol-discuss-unsubscr...@archive.org
Re: [ol-discuss] ISBN with X
Thanks for you advice, Luciano and Karen. I’ll just ignore the '900' then. If I understand you correctly, you can calculate the ISBN-13 easily for every ISBN-10. Which brings me to two question: (- What is ISBN-13 for? Until now, I always thought it extended the number of possible registered books but it can’t if all of it’s extra digits are fixed. But that’s not a question for this list, you didn’t design it, sorry.) - Could we implement a bot which adds missing ISBN-10/13 based on the ones that are there? You then wouldn’t have to bother adding both. xan. ___ Ol-discuss mailing list - Ol-discuss@archive.org http://mail.archive.org/cgi-bin/mailman/listinfo/ol-discuss Archives: http://www.mail-archive.com/ol-discuss@archive.org/ To unsubscribe from this mailing list, send email to ol-discuss-unsubscr...@archive.org
