Peter, If you have a list of the biblionumbers, you can use the Batch Record Deletion tool in Koha to remove all the items and bibs associated with that biblionumber. If you have a list of barcodes or itemnumbers, you can use the Batch Item Deletion Tool in Koha. Cheers, Joy On Sun, Dec 30, 2018 at 6:01 AM Peter Lau <peter.lau@yccece.edu.hk> wrote:

How can I delete a group of bib records or item records that I have retrieved from Koha based on certain criteria?
