Reposting from the headings list:

  I just wanted to let people know that  the LCSH* are available for
download in MarcXML format at http://www.ibiblio.org/fred2.0/authorities/
  .

The data are public domain within the United States, but may be
copyrighted in other countries; please check with LC if this may
affect you.

The asterisk is present due to certain problems identified during
validation checks; the data were downloaded during the first weeks of
december from authorities.loc.gov, and reflect certain differences
between that site and the, authoritative authorities (that sounds so
odd:).

The differences are very minor, and affect only a tiny number of
records; however, until they are brought fully in to alignment they
should not be used without verification  for submission to co-
operative cataloging programs or other in other situations where zero
defects are essential.

See the README file at http://www.ibiblio.org/fred2.0/readme.pdf for
more information.

The Fred 2.0 project is dedicated to the memory of Prof. Fredrick G.
Kilgour, 1914-2006.
