Essential reading: LC subject headings report

A must read: Library of Congress Subject Headings: Pre- v. Post-Coordination and Related Issues [pdf]. Some snippets from the press release:

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 recommended, and the ABA Management accepted, that LC catalogers continue to apply pre-coordination of LCSH terms.

... Many of the pre- vs. post-coordination decisions documented in this report address recommendations recently made in the report of the Working Group on the Future of Bibliographic Control, especially section 4.3 “Optimize LCSH for Use and Re-Use.” LC will be responding to specific recommendations from that Working Group report later this year.
