The MARC Record Translation Program (MARC RTP) might be a useful tool for folks importing records. While its main purpose is to change MARC into other formats it does have a nice feature for finding all the MARC fields. The report gives (1) the total number of records (2) which tags or subfields appear (3) which tags or subfields appear in every record (4) which tags or subfields appear more than once (5) the maximum number of characters needed to store the longest possible piece of information for each tag or subfield. It is also a good tool for finding problems in coding, MARC fields that don't exist but have been used, for example. MARC RTP is free and available in versions for Windows, Linux, and Solaris. http://www.loungebythelake.com/marcrtp/index.html Sincerely, David Bigwood bigwood@lpi.usra.edu Lunar & Planetary Institue http://www.lpi.usra.edu/library/whats_new.shtml Cataloging News http://www.catalogablog.blogspot.com/
