AUTHORITY CONTROL
Chapter 2. AUTHORITY CONTROL
The Authority Validation Hierarchy
The authority validation hierarchy determines the order in which authority records are searched during authority control processing. Your validation hierarchy is set in your User Account by your User Administrator (see the RESEARCHit User Administration User Guide or VERSO User Administration User Guide for details), and may include records from sources such as the Library of Congress, National Library of Canada, Medical Subject Headings, etc.
During authority control processing, the system searches authority records from the top of your validation hierarchy down, until a match is found. When a match for a bibliographic heading is found in an authority record at the top of your validation hierarchy, the bibliographic heading is flagged as “VALIDATED” and the remaining authority records are not searched.
