https://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=41739 --- Comment #2 from Esther Melander <esther.melander@bywatersolutions.com> --- I have not seen an instance where merging different authority types did work, though it might be possible. Regardless, the behavior described in Bug 25387 still happens: "for example merging Turkey(topic) with Turkey(geographic) the result is all 650$aTurkey dissapear" "I recently tried merging a 155 (genre) with a 150 (topical). I wanted the corresponding 655 to survive and the 650's changed to 655 with the correct link. The merge appeared to fail as both merge candidates disappeared - meaning I can't find them in the database." The heading disappears from the bibliographic record and in the one example from the database entirely. I have experienced this when merging a topical term with a genre. Ideally, the headings in the bibliographic record should be updated to the surviving heading and linked. That does not happen. -- You are receiving this mail because: You are the assignee for the bug. You are watching all bug changes.
