Metadata: OCLC Begins Enriching WorldCat Records with FAST Headings

From OCLC:

FAST (Faceted Application of Subject Terminology) is a fully enumerative faceted subject heading schema derived from the Library of Congress Subject Headings (LCSH), a widely-used subject-access vocabulary published and maintained by the Library of Congress. The development of FAST has been a collaboration of OCLC and the Library of Congress with advice from members of the ALCTS/SAC/Subcommittee on FAST.

Beginning in September 2013, OCLC is systematically adding FAST headings to WorldCat bibliographic records.

The records affected will already have LCSH assigned, and the routines will be applied only to records that are attributed as being English-language-of-cataloging.
