Subject: Re: [BIBFRAME] Instance of ISBNs in MARC records

 

In SLC's database of over 300,000 records, over 169,000 have no ISBN, over 114,000 have one, over 19,000 have two, and the number of ISBNs ranges up to 36 in one record.

 

For us, Instances can't be based on ISBNs.

 

 

Total Records: 315389
