Hi Caroline and all, to add to the list of things: - 942$c is used as the pre-selected item type when adding new items. - 942$c will be used for record level article requests to determine which circulation rule applies. - I also believe that 942$c plays a role in record level hold requests, but I couldn't quite pinpoint that. I seem to remember that it was used for the max number of possible record level holds for an item type. Hope that helps, Katrin On 15.10.21 16:22, Caroline Cyr-La-Rose wrote:
Hello!
I'd like to add to Indranil's explanation.
952$y is mandatory for circulation IF item-level_itypes is set to "specific item". Otherwise, 942$c is used as the item type for circulation.
Another thing that I have observed about 942$c is that it is indexed for the search in the same way as 952$y. So if you have records without items (for journal articles, websites or ebooks for example), these will still be searchable through the item type filter.
Also, if 942$c and 952$y are not the same in one record (for example, 942$c is Book and 952$y is Reference), they will show in the results of a search for either type.
I'm making a note to compile all our comments to add into the manual, since that's where you searched for the information first. https://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=29252
Best regards,
Caroline

Hi Tasha,
942$c - defines the type of material the bibliographic record represents, sort of like it's GMD (general material description). Has no bearing on circulation of material. Stored as marcxml in biblio_metadata.
952$y - defines the item-level item, and is used mandatorily for Koha's circulation rules which work as a permutation of (a) branchcodes (b) patron categories and (c) item-level item types. Stored as itype column in items table.
Hope this helps Indranil

Good afternoon,
I recall reading (in the Koha manual?) the explanation for why it is advantageous to define Koha item type in the bib 942 field. I believe it has to do with exporting records, or the scope of records that is included when doing some type of report? I'm trying to locate that information again, but can't find it for the life of me.
Does this seem familiar to anyone? Thanks.
