Chris, You should look for the pref item-level_itypes and its documentation.

They appear to be mapped to koha fields biblio.itemtype and items.itype respectively. Please could someone explain to me the difference between them? In particular when I define a circulation rule for a specific item type, which one does it use? I am using Koha 17.05 Thanks!
