Thanks to Chris and a script from George Williams, it worked like a charm. Almost. With a few of them. After a lot of trial and error, I think I might have found the problem: my SQL queries can’t find the item type EBOOK, or any data associated with bib records of that type. Since there aren’t any items associated with these records, that makes sense, but… Is there any way to run an SQL report looking for something in the biblioitems.isbn field when there aren’t any items attached? The 020 field has them, and I can put the ISBN in the search box, so the system knows they’re there. Thanks! And if I’m totally confused, could someone point me in the right direction? I’m about to leave for the day, and Monday is a holiday here in the States, so I might not be checking e-mail for a while. Have a great weekend everybody.

Hi Fred You might be able to write a report to get all biblio with no items attached, of a certain type and then use that list of biblionumbers in the bulk biblio delete. Hope this helps Chris On 30 August 2019 1:51:31 AM NZST, "King, Fred" <Fred.King@Medstar.net<mailto:Fred.King@Medstar.net>> wrote: Esteemed Colleagues, My library has a collection of about 5000 online books that are in Koha with bib records and no items. The publisher periodically archives titles so they're no longer available, and I have a list of them that I'd like to remove from Koha. The problem is that my list consists of ISBNs and that there are over 450 of them. I could search and delete one-by-one, but that's an awful lot of searching and deleting. Is there an easier way? We're on Koha 17.05* and Ubuntu 16.04. *I know, I know, but I'm hoping to get a new server before I upgrade.
