Put the HAVING clause inside a subquery that determines which bibs' 
items should be included -- something like this (untested):

SELECT b.biblionumber, i.homebranch, t.isbn, b.title, b.author, i.ccode, i.itype
FROM items i
LEFT JOIN biblio b USING (biblionumber)
LEFT JOIN biblioitems t USING (biblionumber)
WHERE i.itemlost=0 AND i.withdrawn=0
AND b.biblionumber IN (
    SELECT b.biblionumber
    FROM items i
    LEFT JOIN biblio b USING (biblionumber)
    WHERE i.itemlost=0 AND i.withdrawn=0
    HAVING COUNT(i.itemnumber) > 1
)
ORDER BY b.title

That's a bunch of data for all items (not lost or withdrawn) on bibs 
that have more than one item (not lost or withdrawn).

HTH,

Paul.
