Hi Elaine

I bet the ones imported just have the data in the marcxml field, so in
order to find them you would use some sql like

SELECT biblionumber FROM (SELECT biblionumber, ExtractValue(marcxml,
'//datafield[@tag="942"]/subfield[@code="c"]') AS comp FROM
biblioitems) as comptable WHERE comp="Components";

Try that and see if you get at least 70 biblionumbers back

One caveat, your mysql server needs to be running at least 5.1.5 for
this query to work (most modern installs will be)

Hope this helps
