https://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=40212 --- Comment #1 from Mathieu Saby <mathsabypro@gmail.com> --- I don't know if there is any community interest in this, but it may be more complex to do than I thought. No standard MARC21 or UNIMARC field seems suitable, so for the development to be acceptable the field would probably need to be configurable for each installation in a syspref. So we can have for example in an given instance a repeatable 999 field, with the name of the list in a $a field, and its number in a $b field. It should concern only public list. 999$aOne list$b1 999$aAn other list$b2 Another approach would be to create a "virtual" field on the fly only when exporting to OAI-PMH. But adding or removing a record from a list would have to trigger an update of the record in the repository, and I don't know if that's possible. Note that the same idea could apply to course reserves. -- You are receiving this mail because: You are watching all bug changes. You are the assignee for the bug.
