Hello, in 2007, january, the ISBN will be on 13 digits. afaik, it will use the standard vendor code, that for instance is : 978+ (isbn-controldigit) +controldigit re-calculated. What will we have to do in Koha ? * modify the DB to handle this longer ISBN * re-calculate all previously entered ISBN ? * rewrite show-isbn-with-dash sub ? * that's all ? -- Paul POULAIN et Henri Damien LAURENT Consultants indépendants en logiciels libres et bibliothéconomie (http://www.koha-fr.org)

Hello,

Yes, it is. You can find all information from ISBN Users' Manual (ISBN-13). http://www.isbn-international.org/en/manual.html
What will we have to do in Koha ? * modify the DB to handle this longer ISBN
It is the must. check 10 and 13 digits automatically.
* re-calculate all previously entered ISBN ?
Need not change any issued 10 digits ISBN. Unused 10 digits ISBN still valid even after 2007, january.
* rewrite show-isbn-with-dash sub ?
Koha need minor change to handle this.
* that's all ?
Almost. -- Best regards 毛慶禎, Anthony Mao, mao at lins dot fju dot edu dot tw ICQ 30941847 Department of Library and Information Science http://www.lins.fju.edu.tw/mao/index.htm TEL +886 2 29052334, FAX +886 2 29017405 Fu-jen Catholic University, Taipei, Taiwan, R.O.C.

a 10 digit ISBN will become 978+10digit isbn + key recalculated. So I think it would be easier on the long term to store everything in 13 digits. -- Paul POULAIN Consultant indépendant en logiciels libres responsable francophone de koha (SIGB libre http://www.koha-fr.org)
