item-level callnumbers are really the only valid type of callnumber,
since callnumber refers to shelf location and bibs don't have shelf
location. There's a separate concept of 'classification' that can
appear at the bib level, but it's really not used very much in
practice in libraries, other than as a reference point. Shelf browse
lists, etc., are generated from the item-level itemcallnumber, which
should always be populated for every item.

The fields dewey and classification don't exist anymore, we now have:

itemcallnumber (combined full call number at the item level) and we
have cn_source and cn_sort (for sorting rules based on the cn_source
value as defined in Administration->Classification Filing Rules)

At the bib level we have biblioitems:

cn_source
cn_class
cn_item
cn_suffix
cn_sort

dewey and classification no longer exist and should be replaced at the
bib level with a concatenation of cn_item . cn_item . cn_suffix and at
the item level with itemcallnumber.

Please see the following reference:

Hope that helps.
