Thanks, but that`s not the case. I have my own records in the other ILS 
(ALEPH to be specific). I extracted the raw data from it in order to 
figure out the best way of importing it into KOHA and to develop  a 
procedure that would give best results with least effort. After success, 
I allowed my colleagues to test KOHA, however the biblio and items 
databases were already outdated. New biblios and items are in Aleph, I 
can extract them and make them KOHA-importable. The problem would not 
exist if there were ONLY new biblios with items, however there are items 
that should be attached to  biblio records already existing in KOHA.

I use a Polish fork developed by Wojciech Zatorski. He is developing an 
"university library" version, I work in a public library, so it`s not 
the best fit, but still better than "mainstream" KOHA. The fork is 
heavily modified 2.4 with additions from later versions. Full 
compatibility is long gone, I guess.

Not my case again :) I have biblios with items with Koha, just need to 
attach more items to those biblios:

read record from file -> look at ISBN in subfield 020a, search 
biblioitems for matching isbn -> if found, import field 952 only with 
biblionumber and biblioitemnumber of the found record. If not found, 
import all fields as a new biblio/biblioitem/item.

I know it would create duplicate biblios, but less than importing 
everything as complete records. Or maybe someone has a better idea?...

Regards,
Tomasz.
