Definition and scope:

The 7XX Heading Linking Entry fields provide a machine link within a system between equivalent or hierarchical headings whether they are structured in the same or different form, are from the same or different authority files or printed thesauri, or whether they exist as separate authority records.

The 7XX field tag identifies whether the heading linking entry field contains an established heading (fields 700-762) or an authorized subdivision heading (fields 780-785).

A relationship that cannot be adequately expressed by the 700-785 linking entry fields is described textually in field 788.
