[Koha] [EXTERNAL] Re: Reason to define Koha item type in 942

[Bales (US), Tasha R]

Very helpful information!  Thank you to everyone who provided clarification!  I think this is what I was looking for in particular:

--"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."--

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.

Best regards,
