ISBN as Barcode
What is this?
If your library does not have a policy of using ISBNs on books as their barcodes, it may cause confusion if this happens by accident.
Why is this trouble?
If a book has a library barcode on it, but the ISBN has been scanned into the item record instead, circulation will not work properly for the book.
Exceptions
Some libraries may use ISBNs as barcodes.
How to Find
If you are in Alma, there is an analysis to search for this issue in the "Looking for Trouble" folder. Go to the "Barcodes" folder and look for the "ISBN" analysis. This looks for 13-digit strings starting with 978 or 979.
If you can search or filter your barcodes by regular expression, you
can use the expression:
/^97(89).{10}$/ or /^97(89)..........$/
