Dear Stefano, i really need your help with this, since i am on a tight deadline, and i do not think i will manage this by myself alone... Tried to make something out of your description in the paper, but without success. Please find attached a small portion of our db, where you may find in field 011$a the ISSN, and we need to make two things, with the existing records: For starters fill 676$a = DDC, with the most appropriate value, and secondly, if possible, wherever there is different suggestion by your algorithm, compared to the already existing DDC value, a log file, something that would allow us to keep record of the already stored and the suggested value, in order some librarian's human eye decides on which is best. I would appreciate your help on this, thank you very much. p.s. attached the sample mrc from our db.
