Item Categories are used to limit searches in the catalog. They are also used to generate monthly statistics for libraries.
Item Category 1 is for the broad type of material.
Item Category 2 is for the age/reading level of the material: ADULT, JUVENILE, or YA-TEEN.
Item Category 3 is for content of the material: FICTION, NONFICTION, or UNKNOWN
Item Category 4 is for how material circulates: whether the item is for CIRCulating, or for INHOUSE use. CIRC is for items that leave the building. INHOUSE is for items that do not leave the building and are not counted as circulation for statistics, but are checked out to patrons to keep track of them (ie, an INHOUSE laptop).
