OCLC supports ACS the OCLC Authority Control services and OCLC/WLN MARS.
The goals of authority control are a) to provide efficient and effective pathways through a catalog's resources and b) to help libraries reduce the cost of authority control while simultaneously helping patrons use library catalogs more effectively.
The benefits of authority control are a) free valuable staff time, b) produce a consistent, effective catalog for patrons and staff and c) to improve access to a library's collection.
Main headings are still qualified by geographic, language, form and topical subdivisions.
Geographic subdivisions can be added to any main heading or main and topical subdivision. They can be added even if an annotation is not present..
Language subdivisions can be used only in combination with specific publication types: Dictionary, Encyclopedias, Phrases, Terminology.
Form subdivisions fall into five categories and one exception. The categories are a) simple replacement, b) obsolete being replaced, c) obsolete being dropped, d) replaced by a main heading, e) replaced by main heading plus $v coordination, and the exception, which is Case Report.
Form subdivision exception, previous form used as a check tag: $v case studies is replaced by "Case Report" as a PT in 650 $v
Topical subdivisions: Changes involve the age groups, pregnancy and new subdivisions. also legislation & jurisprudence and statistics and numerical data.
There is a machine readable authority file and printed instructions (1999) and the newly issued bibliographic records and practice (in 2000).
Goal is to implement new practices for compliance with NLM current practice.
