There's a new MARC 21 authorities to MADS mapping out to correct these (and other) problems. See: http://www.loc.gov/standards/mads/mads-mapping.html Please report any errors to us. We should have a transformation available (MARC authorities to MADS) soon.

In addition, after doing some queries with a recent copy of the LC authority file (2005-09-14), we noticed that there are 7 records coded with a tag of 111 which have an LCCN prefix of sh and there are 466 records coded with a tag of 130 which have an LCCN prefix of sh. > > There doesn't appear to be any mappings that indicate 111 authority="lcsh" and 130 authority="lcsh". The only mappings for 111 and 130 are: 111, 130 and 008/11=a authority="naf". > > BTW, for reference here are the LCCN's for the 111: > > sh 85053891 > sh 85053892 > sh 85117102 > sh 85018098 > sh 85019367 > sh 93010664 > sh 93010136 > > BTW, for reference here are the LCCN's for the first 7, 130: > > sh 85132126 > sh 85132127 > sh 85132128 > sh 85132129 > sh 85132130 > sh 85132131 > sh 85132132 > > > Andy. > > Andrew Houghton, OCLC Online Computer Library Center, Inc. > http://www.oclc.org/about/ > http://www.oclc.org/research/staff/houghton.htm >
