Authority Thesauri<br />

A thesaurus is a separate file of all established and unestablished terms in<br />

the authority record database. It provides the full relationships between<br />

terms and creates the catalog cross-references from the authority file<br />

records.<br />

The following diagram shows the basic structure of the authority<br />

database and its relation to the bibliographic database:<br />

Levels of Authority Control<br />

Cross-References Only<br />

Cross-reference only configuration permits the use of the X-refs button in<br />

the e-Library. Searches on improper headings will produce a browse<br />

window that will point the user to the proper heading. Searches on<br />

proper headings that have related terms will cause the X-refs button to<br />

appear, which if selected will display a list of related terms.<br />

As new catalog records are added to the system, they are not checked<br />

against the authority indexes. Headings in the catalog records are not<br />

verified automatically by the system, but a cataloger can always manually<br />

search the authority database and make corrections to bibliographic<br />

records. Authority records may be created or edited with the intent of<br />

creating new cross-references.<br />
