Hi everybody, Here is the solution I propose for LC and any other callnumber : * a field has already been added in items table. It's called itemcallnumber. * this field will be "connected" to : biblio dewey OR LoC number OR manual & local classification. if connected to dewey or LoC, it will automatically be filled. So every library can have it's own callnumber system. Sounds this good ? For 2.0 I've no other suggestion than the workaround suggested here. The dmoses one being the best, imho. NOTE : why put the callnumber in items & not in biblio you may ask ? it's because some libraries may have 2 differents callnumbers for 2 items of the same biblio. Sounds silly (& quite old), but exists. And you can't ask a 100 000 items library to reorganize it's shelves ;-) -- Paul POULAIN Consultant indépendant en logiciels libres responsable francophone de koha (SIGB libre http://www.koha-fr.org)
