Subject: Multiple values bug in subfield function for MARC::Record

From: "Chris Cooke, Contractor, Code 5596" <chris.cooke.ctr [...]>
There is a bug in MARC::Record when you have multiple values for a field, such as mutliple ISBNs (field 020). The subfield function only returns the first value, even in an array context. But the field function correctly returns an array. I parsed a file using MARC::File::USMARC, and then for a sample record, did this code: print "subfield test\n"; @isbns = $marc->subfield('020', 'a'); foreach my $isbn (@isbns) { print " isbn from subfield function: $isbn\n"; } print " there were " . scalar(@isbns) . " isbns from subfield function\n"; print "field test\n"; @isbns = $marc->field('020'); foreach my $isbn (@isbns) { print " isbn from field function: " . $isbn->subfield('a') . "\n"; } And it printed this result: subfield test isbn from subfield function: 9781574443066 there were 1 isbns from subfield function field test isbn from field function: 9781574443066 isbn from field function: 1574443062 (alk. paper) there were 2 isbns from field function As you can see, the subfield function threw away my second ISBN. -Chris
