Hi Hector
Hi Michael, I have this as biblio record, can I change it to "specific item"?
I would assume so. If you're not sure what setting is correct for you, the manual may help: https://koha-community.org/manual/18.05/en/html/02_administration.html#item-...
Is there a procedure to do that?
Koha system preferences can directly be changed as a Koha user with superlibrarian rights. You'll find this preference in in Koha ,menu "Administration > Global system preferences > Cataloging > Record Structure".
I don't remember changing this preference, is it the default?
The default in Koha 18.05 is "specific item". Hope that helps. Best wishes: Michael -- Geschäftsführer · Diplombibliothekar BBS, Informatiker eidg. Fachausweis Admin Kuhn GmbH · Pappelstrasse 20 · 4123 Allschwil · Schweiz T 0041 (0)61 261 55 61 · E mik@adminkuhn.ch · W www.adminkuhn.ch
