In the client, you can do a bibliographic search by "standard identifier number" and it searches a bunch of different possible fields (the corresponding power search: (((ISBN="1234" OR ISSN="1234") OR (OSI="1234" OR STRN="1234")) OR (((PN="1234" OR CODEN="1234") OR OCN="1234") OR (SOA="1234" OR UPC="1234*")))). We would also like to see this option in Leap.

Currently, staff don't get results for a scanned barcode unless they choose the correct field to search and the indicators in the record are properly set. This means they often get no results and incorrectly assume we don't have the record. In the client, you could easily use the "standard identifier number" search to pull up records with that number in it regardless of whether the MARC record considered it an ISBN, a UPC, or an OSI number.
