[Koha] Reason to define Koha item type in 942

[Caroline Cyr-La-Rose]

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,
