I have made our catalog of MARC records available for anyone who wants them for testing. The file contains about 22,000 records containing about 53,000 items. It has the holdings in field 856. The records are pretty clean but it is the actual catalog of our collection, so it is not perfect. I just finished doing some clean-up on the catalog. Using MarcEdit and MARC RTP I was able to spot incorrect or obsolete fields and subfields and change them. I've replaced the file in our FTP site with the cleaned-up version. There are readme files there that explain the file in greater detail. For anyone interested the URL is: ftp://www.lpi.usra.edu/pub/outgoing/bigwood Sincerely, David Bigwood bigwood@lpi.usra.edu Lunar & Planetary Institute http://www.lpi.usra.edu/library/whats_new.shtml Cataloging News http://www.catalogablog.blogspot.com
