LC to Add Subject Category Codes to Selected Subject Authority Records

The Library of Congress has announced they will add subject category codes to selected subject authority records.
No earlier than August 2012, the Policy and Standards Division (PSD) of the Library of Congress will begin an experiment to add subject category codes (MARC 21 tag 072) to authority records for subject headings. It is anticipated that the addition of this information will enhance the usability of LCSH on the Semantic Web; assist catalogers by allowing integrated library systems (ILSs) and resource discovery platforms to provide a list of the subdivisions that are appropriate to headings being assigned; and improve automatic heading string creation and validation in ILSs and resource discovery platforms.
