Library of Congress releases LCSH as linked data

Yesterday the LOC announced it is releasing it's first service on id.loc.gov which contains LCSH terms represented as RDF/XML, N-Triples and JSON.

The vocabulary is available for download, or can be searched online at http://id.loc.gov/authorities/

Here are some sample snapshots:
