      Description

      Use https://github.com/folio-org/folio-isbn-util for isbn normalization
      Possible solutions:

      • Normalize values in 020 $a fields before saving MARC records in SRS - MARC source records will be stored with normalized isbn values and Instance records mapped from such MARC will have identifiers with normalized isbn values.
      • NOTE: A MARC bibliographic record can have many 020 $a's with differing values. See attached MARC file for some examples
      • To normalize:
        • If 020 $a is a 10 digit ISBN
          • Add separate 020$a with the 13 digit version.
          • Do not remove the original 020$a with the 10 digit version
          • If the newly-created 020 $a with a 13 digit version duplicates an existing 020 $a in the record, do not add another 020$a
        • If 020 $a is a 13 digit ISBN that begins with 978
          • Add separate 020$a with the 10 digit version.
          • Do not remove the original 020$a with the 13 digit version
          • If the newly-created 020 $a with a 10 digit version duplicates an existing 020 $a in the record, do not add another 020$a
        • If 020 $a is a 13 digit ISBN that begins with 979
          • o not normalize the ISBN and do not add any additional 020$a into the record
      • To support match on existing Instance Identifiers - extend instance.identifier schema to hold normalized version of ISBN, leave the original value intact.
