http://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=14287 Bug ID: 14287 Summary: Preserve valid ISBN-13 identifiers if they start with something else than 978 Change sponsored?: --- Product: Koha Version: master Hardware: All OS: All Status: NEW Severity: enhancement Priority: P5 - low Component: Cataloging Assignee: gmcharlt@gmail.com Reporter: olli-antti.kivilahti@jns.fi QA Contact: testopia@bugs.koha-community.org CC: m.de.rooy@rijksmuseum.nl If Business::ISBN cannot make an ISBN-10 out of a valid ISBN-13 starting with 979, then we should preserve the ISBN-13 instead of getting rid of it. ISBN-13 starting with 979 is valid as well and in a few years starting with 980 might be as well as the ISBN supply is running out. This patch modifies the C4::Koha::NormalizeISBN() to preserve the original ISBN if type conversion fails. Also Koha should support all ISBN-variants interchangeably, see Bug 10192. Some Items have ISBN-10 from some sources and the exact same Item can have ISBN-13 from other valid sources. Maybe the easiest solution is to migrate all current and future imported ISBNs to ISBN-13 -variant since according to the same wikipedia article, the conversion is quite easy. -- You are receiving this mail because: You are watching all bug changes.
