https://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=10756 --- Comment #12 from Magnus Enger <magnus@libriotech.no> --- I have signed off the two original patches from Mason. As noted in the sign off message I found a problem for 13 digit ISBNs that do not start with 978. The third patch attempts to fix this. I think my patch needs a signoff, so I am leaving this bug as "Needs Signoff". -- You are receiving this mail because: You are watching all bug changes.
