   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.

   The methods `get_heading_from_authority_field` and `normalize_heading_for_local_search` borrowed from [pulibrary/authority_control](https://github.com/pulibrary/authority_control/blob/main/lib/authority_control/record_update.rb).
