Hello all, we are still working on our newly installed Koha 2.0.0 at the International Library in Düsseldorf/Germany and puzzled by some new problems. 1. Where do I enter the Dewey classification information when adding a new biblio? 2. How can I enter closing or opening days? (i.e. days that should not be a due date - our library is closed on Fridays and Sundays, for public holidays and for a whole month in summer) 3. When I use bulk import of MARC records into our new Koha database, what is the most efficient way to assign each item a barcode? We are still working with a conventional card catalogue at present. Library staff started scanning ISBNs in a large ASCII file to get MARC records. During our "migration" to Koha, we would stick a barcode on each book and would have to tell the database which barcode is connected with which database item. Thank you very much for the answers I got regarding the problems I was trying to solve in March. I appreciate your support and am looking forward to receiving answers to this new set of questions. Best wishes from Germany, Stefanie Mohsennia
