Getting closer to actually running Koha! I'm installing 3.2., because I've been told it's more useful for the type of library (small, specialized, complicated interrelationships) catalogue we've got. One of the things I want to do is to be able to search on and link to our 001 fields (control number - these were generated from our original catalogue system). This would enable me to make use the linking ability of the 774 field without having to import everything first so I have the 999c Koha number, and then going back and adding these in where needed. I /think/ the way to do this is through keyword to MARC and Koha to MARC mapping. But I can't find any documentation that explains what these features do, or how to use them. I found that in the Koha to MARC mapping, biblioitems level there is the lccn 010 a LC control number We don't have LC control numbers for any of our material at the moment. If I go in and change this to 001 a it doesn't change the label - which makes me suspicious that I haven't done the correct thing. Is there a way to add a MARC tag to the biblioitems list? Have I missed a step? Is that where the Keywords to MARC comes in? I could really use more information on these features. I feel like I'm blundering around in the dark in the midst of some very delicate machinery, and I don't want to break anything. Thanks -- Elaine
