Thanks for the heads up regarding the items and biblioitems. Investigating further, I found that the Koha to MARC Mapping is set up such that under biblioitems, itemtype maps to 942$c (the Koha [default] item type) and that under items, itype maps to 952$y (the Koha item type). Further, I found that changing the biblio framework also affects 942$c (Koha [default] item type). I suspect that two of my records have a 942$c for the item type I’d like to delete. Tomorrow I’ll look into mapping the 942$c and 952$y to see if it is possible to align biblio frameworks with item types.
