FAQS: Koha Circulation

How does the biblio level item type (942$c) facilitate title level holds in Koha?

Holds use circ rule to determine whether a title is available for holds. Circ rules may include a wild card (*) to apply circ rule to "all branches," "all patron categories," "all item types," etc. While this works well for traditional circulation, it does not work for holds processing. An item is not attached to a title-level hold in Koha until the hold is filled. Koha uses the biblio level item type to insure that limitations on the number of holds a single patron is allowed based on item type are handled properly if other attributes of the hold include a wild card.
