Hello all currently we are using koha 3.8.4. i know this version of koha has Batch item modification, this help us to change only on 952y, but my interest is to change the biblo item type i.e 942$c,

Koha does not yet have batch edit functionality for bibliographic records. The feature has been written but it is still being tested. As far as I know the only option for doing batch biblio edits is to export the MARC records, batch edit in an external program like MarcEdit, and re-import. -- Owen -- Web Developer Athens County Public Libraries http://www.myacpl.org
