You might find this page useful, since it does provide some isbn examples:


The problem with your query is that isbn is not a field in the biblios
table; it is in the biblioitems table.  You'll need to join that table
to the query, perhaps like the one below.

SELECT bi.isbn, i.itemcallnumber, b.biblionumber, b.title, b.author, b.copyrightdate,
       i.barcode, i.datelastseen, i.issues AS totalcheckouts,
FROM items i
LEFT JOIN issues
USING (itemnumber)
LEFT JOIN biblio b
USING (biblionumber)
LEFT JOIN biblioitems bi
USING (biblionumber)
WHERE homebranch = <<Home Library|branches>> AND location = <<Shelving location|LOC>> AND i.withdrawn=0 AND
i.itemlost=0 AND i.damaged=0 AND i.itemnumber NOT IN (SELECT issues.itemnumber FROM issues)
      AND  YEAR(NOW())-YEAR(i.datelastseen) > <<Years NOT seen>>
ORDER BY i.itemcallnumber ASC
