#### Question

Sometimes there are additional ISBN numbers listed in analytics that are not found in the actual BIB record, where are these ISBN numbers coming from?

If a bibliographic record is created and saved with an old-formatted ISBN-10, Alma also indexes the more current ISBN-13.  The record is not edited or changed, but the ISBN-13 is indexed behind the scenes upon saving the BIB record.

As a result the indexed ISBN will be seen in analytics reports and can be used in a repository search.

Note:

For Classic Primo, when using the out-of-the-box normalization rules you will be unable to search by the ISBN-13. However, there are transformation routines (ConvertISBN13toISBN10" / "ConvertToISBN13) which can be added to the rules and allow for searching by both ISBN-10 and ISBN-13. If assistance is needed with setting up these rules please submit a case to Primo Support.
