Nitesh, I’ve never gone through a data conversion from another ILS, but when I look at the MARC records in our catalog for books with several items, they all appear with multiple MARC 952 fields … like your second example below. (My repeated 952 fields also each have the call number, shelving location and other necessary subfields filled in … not just the barcode). Therefore, I believe that is how you want your output to appear. Can you test it with a small batch, just a few sample records, to see whether it works?

I have been working in KOHA since more than 1 year now. When ever there is a requirement of data conversion, we are only able to convert all the records, but not the items associated with it. The problem is with not knowing the proper use of "regex" in MarcEdit. Here is a sample of what we have: =100 \\$aMr. X =245 \\$aTest Book =952 \\$p5412,2154,8745,2134 While the output of MarcEdit should be like this: =100 \\$aMr. X =245 \\$aTest Book =952 \\$p5412 =952 \\$p2154 =952 \\$p8745 =952 \\$p2134 so that when it is imported in koha, item barcode also gets imported, what should I do to get this done? Please Help me. Regards. -- Er. Nitesh Rijal Sr. Computer Programmer nitesh@healthnet.org.np<mailto:nitesh@healthnet.org.np> +9779841458173
