Bulk downloads of the Library of Congress *Name* Authority File (NAF) are now available. The current bulk download is only MADS/RDF. We'll make a SKOS/RDF download available in the near future. We are offering two serializations: n-triples and RDF/XML.
The LC *Subject* Heading (LCSH) file continues to be available for download as SKOS/RDF, but now LCSH is also available in MADS/RDF (in the same serializations). The MADS/RDF enables the identification of types for subject headings and subheadings.
They may be downloaded here: http://id.loc.gov/download/
The data dumps are very much a work in progress. Please report problems, issues, and wishes on the ID.LOC.GOV listserv:
