[Koha] Reason to define Koha item type in 942

[Katrin Fischer]

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
