I haven't actually tried this, but there is a report in the Koha SQL Reports library that looks like it can be adapted to do what you want. The report is called "Records with item count". I reckon you just need to add a 'HAVING' clause which identifies records with more than one copy:
*SELECT DISTINCT CONCAT('<a title="Search for all records sharing the title:',b.title,'" href="/cgi-bin/koha/catalogue/search.pl?q=ti%3A <http://search.pl?q=ti%3A>', REPLACE(REPLACE (b.title, ' ', '+'),'?',''),'">Search</a>') AS "Search for Title", b.biblionumber, CONCAT('<a href="/cgi-bin/koha/catalogue/detail.pl?biblionumber= <http://detail.pl?biblionumber=>',b.biblionumber,'">',b.title,'</a>') AS "Item Title", b.author, t.editionstatement, t.publishercode, t.isbn, count(i.biblionumber) AS "Copies" FROM biblio b LEFT JOIN biblioitems t USING(biblionumber) LEFT JOIN items i USING(biblionumber) GROUP BY b.biblionumber HAVING copies > 1 ORDER BY Copies ASC* Like I say, I haven't tested it, but I think it should work. Somebody else may have a better way.
