5.31 Linking entry vocabulary to valid headings

"USE" references guide users from non-preferred terms to valid headings. Non-preferred terms are usually synonyms or near-synonymous, but may be different arrangements or configurations of the elements in valid headings. Occasionally, "USE" references may be used to guide users from broader or narrower terms which are not valid subject headings to authorized headings.
