FIELD DEFINITION AND SCOPE

Information that identifies the specific audience or intellectual level for which the content of the described item is considered appropriate.

Used to record interest and motivation levels and special learner characteristics. Information about the target audience and/or intellectual level may also be recorded in coded form in field 008/22 (Target audience) for some types of material. (Note: If a computer files or visual materials record has both reading grade and interest age or interest grade level information present in 521 fields, field 008/22 is coded based on the interest age information.) Notes that include restrictions on access are recorded in field 506 (Restrictions on Access Note).

The note is sometimes displayed and/or printed with an introductory term that is generated as a display constant based on the first indicator value.
