[Koha] Journal articles and analytical records

All, We are just now loading our records, but have thousands of analytic records that we will be experimenting with. Like Elaine and Beda, we are looking at using the 773. I was thinking about putting the host item system number in the subfield $w and maybe using the subfield $o for something to tie directly to the individual item. In our current system we are using the item part, and I was thinking of either trying that or using the barcode or itemnumber in the $o. What subfields have been used in your testing, Elaine? I am relieved to know we are not alone in looking at this and look forward to working with everyone. We have absolutely no funds to contribute but sweat equity works, I hope. Thanks! Linda
