[Koha] Dewey call numbers in MARC/Koha

With the help of various kind people on this list I'm gradually getting my head around MARC. Our library staff complained the other day that Dewey call numbers weren't showing up in the catalogue, even though they had entered them in under MARC tag 082. It seems that (by default) Koha is using a different tag (can't remember the number but it's one of the 9xx's) for the call number it shows in the catalogue. Is there a reason for this? What's the best way to get around the problem? Should I modify the MARC<->Koha link to use 082 instead or should I just copy the contents of 082 into Koha's own tag? -- Kevin O'Rourke ICT Coordinator, National Teachers' Institute, Kaduna, Nigeria 062 316972
