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. (UNIMARC)
