[Koha] Biblio deletion

[library]

Goodmorning

Can anyone direct me to instructions on how to batch delete biblio records.
I managed to batch delete the items attached to the records and now I need
to delete the records themselves, but I really don't want to do this one at
a time for over 1100 records. …Or have I misunderstood the process
entirely.

Best wishes
