Added entry in which the name is not controlled in an authority file or list. It is also used for names that have not been formulated according to cataloging rules. Names may be of any type (e.g., personal, corporate, meeting).

Used when one of the other access fields (e.g., 1XX (Headings) or 7XX (Added Entries)) cannot be used because the level of control and/or structure of the name does not meet the requirements of the other access fields. Field 720 should not be used for uncontrolled names intended to provide subject access. In that case, field 653 (Index Term-Uncontrolled) is preferred.

The parts of names consisting of several parts can be recorded in whatever order is desired. Field 720 is repeated for multiple names.
