Hello all, hi tungsten, I've read your irc question. Something has to be explained... Callnumber explains where the item is located physically Classification helps finding books on a topic/subject. In most libraries, the callnumber is a classification (books are ordered by Dewey, or by LC...) But in some, the callnumber has nothing to do with the classification. So, in Koha, callnumber and classification are different things : * the callnumber is attached to ITEMS. * the classification is attached to BIBLIO. a systempref parameters tells Koha to define automatically callnumber from a biblio field : itemcallnumber. I realize I've forgotten it in installer... I fix this immediatly. You can add it manually in your systempreferences, just add a "itemcallnumber" entry, with a value of FieldSubfield (676a -dewey in UNIMARC-, 680a -Loc in UNIMARC, or any other bibio field/subfield) NOTE : this works for manually added biblios only. For biblios migrated with bulkmarcimport, you must copy the callnumber yourself (in bulkmarcimport.pl) Is it clear ? -- Paul POULAIN Consultant indépendant en logiciels libres responsable francophone de koha (SIGB libre http://www.koha-fr.org)
