Hi, I'm trying to set up MARC links and MARC structure. Before making changes to what the defaults are, I'm trying to see how those defaults would meet our needs. We do not have a pre-existing database so have some flexibility. I will be using call numbers like the following on my spine labels. Since we have a small collection, many times we will not be using any numbers after the decimal or only a few in areas where our collection is strongest, so we use the first 3 letters of the main entry at the end of the call number (usually authors last name, sometimes title main entry). REF 023 .3 RON The defaults in Koha are: biblioitems.classification 942j Location (call number prefix code) biblioitems.dewey 942k Classification base (DDC to decimal or LCC letter class padded after single lett biblioitems.subclass 942l Classification subclass (DDC after decimal or LCC number after letters items.itemcallnumber 952k Call number (combined) To test results I put the following in these fields in one record of a Liblime demo record. 942j prefix 942k dewey 942l subclass 952k combined Here are the results as they show in the catalog: http://opac.liblime.com/cgi-bin/koha/opac-detail.pl?bib=26305 Why does "prefix" come after "dewey"? One reason I'm looking at this is that, I'm trying to get the newer barcode generator using Gaylord 8511 labels working for us using the kind of call number we use. In this example if I check Dewey / Call Number, Classification, Item Call Number, and Sub-Class here's the result for the spine label: dewey sub combined Does anyone have a suggestion on how we should be entering our call numbers into the system to have it look correct in both the OPAC and on the spine labels? I just can't seem to riddle this out. --Jason
