Comment 1 for bug 1463469

I can't confirm this bug on our production system (which is 2.8ish). So far all our tests in retrieving bibs with only UPC 024 and no ISBN 020 or ISSN 022 have yielded no issues.

In my logs, I can see our system passing the UPC code in the correct part of the URL retrieve to Syndetics.

For fun, a terrible SQL I crafted to find bibs that fit the pattern:

SELECT DISTINCT record FROM metabib.real_full_rec WHERE tag = '024' AND ind1 = '1' AND record NOT IN (SELECT DISTINCT record FROM metabib.real_full_rec WHERE tag = '020' OR tag = '022') LIMIT 10;

Marking bug incomplete pending further information or confirmation of issue on other systems. Maybe it's a 2.7 specific bug (though to my knowledge, nothing changed between 2.7 and 2.8 in this area).
