Here are two useful reports to generate a list for barcode label creation

Book list between range of accession numbers.
SELECT items.barcode,items.itemcallnumber

FROM items LEFT JOIN biblioitems ON (items.biblioitemnumber=biblioitems.biblioitemnumber) LEFT JOIN biblio ON (biblioitems.biblionumber=biblio.biblionumber) 
WHERE items.homebranch =<<Branch|branches>> AND items.barcode BETWEEN <<From Acc>> AND <<To Acc)>>
ORDER BY LPAD(items.barcode,30,' ') ASC

Call number list

SELECT items.barcode,items.itemcallnumber
FROM items
LEFT JOIN biblioitems ON (items.biblioitemnumber=biblioitems.biblioitemnumber)
LEFT JOIN biblio ON (biblioitems.biblionumber=biblio.biblionumber)
WHERE homebranch = <<Pick your branch|branches>> AND items.itemcallnumber LIKE <<Call number LIKE (USE % FOR wildcard)>> 
ORDER BY items.itemcallnumber ASC

Download download the report.

Another method is prepared a list in a spreadsheet and save it in .csv format.
Copy and paste the list in a spreadsheet (e.g. Libreoffice, OpenOffice).

Save the sheet as a .csv file.
