Hi Katrin -- many thanks for the reply, you "hit the nail on the head."

We did have for this record:

=600  \\$a $915837

which is the "RLIN" for the author (how it got there, from the 100$a, with 
an empty 600$a is a mystery), and now after deleting the RLIN, there's no 
600 and the web page is just fine.

Would you by any chance have a suggestion as to a mysql query to find other 
records that contain the same error.  I've tried:

SELECT biblio.biblionumber, biblio.title, biblio.author
FROM biblio
RIGHT JOIN biblioitems ON biblio.biblionumber = biblioitems.biblionumber
LEFT JOIN items ON biblio.biblionumber = items.biblionumber
WHERE ExtractValue(marcxml,'//datafield[@tag="600"]/subfield[@code>="a"]') 

but get nothing. Maybe (wild dream?) there's no other erroneous records, 
but much more probably the mysql code misses the truth (it runs without 
apparent error, but...)

Again, many thanks and best regards -- Paul
