   These scripts are intended to find exact matches to determine if LC terms can be added to new 6xx fields programmatically. The codes use adapted methods from [pulibrary/authority_control](https://github.com/pulibrary/authority_control/blob/main/lib/authority_control/record_update.rb).  The methods strip subject headings in LC authority MARC records and 653 fields from bibliographic MARC records down to simple strings. It also compares the strings for exact matches.
