I'm trying to determine whether there is some way within Koha to be able to restrict the loan of certain types of materials to certain types of borrowers. In the itemtypes table, there are blanket settings for loan lengths, number of permitted renewals, and rental charges, and in the categoryitem table rental discounts, reserve charges, fines, reminder notices, etc. are mapped against categories of borrowers and item types. There is also a field labeled "restrictedtype" and in the Koha sample database the value of this field seems to always be NULL. If I were to change the value of this field for a given itemtype and category of borrower, would this prevent that category of borrower from borrowing that particular type of item, or is there another way to prevent certain categories of borrowers from borrowing certain types of items?
