Re: [Koha] Delete Biblio if no matching items found?

I have imported a MARC file 2-3 times with the same records, getting errors some times so fixed and imported the same again and again.

Have you tried using the "Clean" option in Administration -> Manage staged MARC records? This will undo a problematic import. -- Owen -- Web Developer Athens County Public Libraries (740) 737-6006 https://www.myacpl.org
