In 2006, the Director for Acquisitions and Bibliographic Access (ABA) at the Library of Congress (LC) requested the Cataloging Policy and Support Office to review of the pros and cons of pre- versus post-coordination of Library of Congress Subject Headings (LCSH). The final report (2/19/08) recommended, and the ABA Management accepted, that LC catalogers continue to apply pre-coordination of LCSH terms.

The LC report documents the recommendations approved in June 2007, regarding further automation of the assignment of subject heading strings, the expansion of machine validation of strings, further simplification of practices including the fixed order of subdivisions, exploration into LC's use of the current generation of sophisticated search engines, the enabling of more social tagging additions to the LC records, and encouragement of Web applications that take advantage of LCSH. On this latter point, LC intends to make LCSH freely available on the Web in a SKOS (Simple Knowledge Organization Schema) format for the world at large.
