As I was reviewing the bulkmarcimport I noticed that the 090 MARC field is used by Koha as the ITEMTYPE fields. In the MARC data I am importing, the 090 "a" and "b" subfields are assigned local LC call numbers. Since Koha assigns "a" as Koha Itemtype (NR) "b" as Koha Dewey Subclass (NR) "c" as Koha biblionumber (NR) "d" as Koha biblioitemnumber (NR) What will happen to my original 090a and 090b fields? Will they still be in the database? If so, will this cause item "issues"? My limited cataloging knowledge tells me that the 001 field is used for the item number information (at least in the colleges I've worked). Is that not the case with MARC21?
