I think at this point it works ONLY with Dewey.... Hopefully soon it will work with both LC and Dewey!<BR>

William, Koha works best with Dewey. You'll probably want to map the<BR>
actual number part of the Dewey number to Koha field 'dewey' in the<BR>
biblioitems table. In the same table, you can map anything that comes<BR>
after the number (the first few letters of an author's name is a common<BR>
example) to the 'subclass' field in the same table. And if you have<BR>
anything before the number (like 'J' for Juvenile, or 'LP' for Large<BR>
Print), that can go in the 'classification' field. I believe that's the<BR>
way Horowhenua Library Trust (http://www.library.org.nz) does it.<BR>
<BR>
In the case of Nelsonville Public Library, the actual call number used by<BR>
the library was stored in a holdings tag, but in a 952 tag, not the 852<BR>
tag. Many ILS programs use the option of 9xx tags to store holdings<BR>
information, because these tags are more flexible than the<BR>
closely-regulated 852 tags. So at NPL (http://www.athenscounty.lib.oh.us)<BR>
the entire call number was mapped to the 'classification' field as the<BR>
data was migrated from the old system to Koha. I'm not sure how the call<BR>
numbers at Unido (http://www.unido.org) are stored -- they may have used<BR>
yet another method.<BR>
<BR>
One word of warning -- if you decide to map the call number from an<BR>
existing holdings tag, you will need to split the existing tag into two<BR>
tags, so you can map one to the items table and the other to fields in the<BR>
biblioitems table. This isn't too hard to do with MARC::Record.<BR>
<BR>
By the way, the little ' in the Dewey number from LC (005.7'2) is not part<BR>
of the number. It's an indication of the appropriate spot to truncate the<BR>
call number if you don't want to use the whole thing.<BR>
