Just FYI--for Windows platforms, the 7-Zip freeware package decompresses
both the TAR and BZ2 extension files to get the final text files.  Be
aware, by the way, that the original TAR file is 637 MB (668,119,040
bytes).  We have a T1 line, and I think it took somewhere around 6-8
hours to download!

         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 <http://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.

Fredrick G. Kilgour, 1914-2006.
