Hello, Does anyone have any ideas regarding my problem with 852/952 $m. The problem is that, in editing all of my holdings data to migrate nicely into Koha, I cannot figure out how to migrate my old 852 $m data (call number suffix, a standard MARC subfield, I have publication years and volume #s stored in this field). When I use MarcEdit to swap fields & edit data, I can write a regular expression that will find all 852 $h, i, and m and move them to 952 $o. However, this only finds & replaces those 852s that have all 3 of those subfields. Most of my records do not have all 3, they only have $h and i. So, when I run a second find & replace to pick up the 852s that only have those two subfields, then a second 952 $o is created. In short, it seems that my choices in regard to $m data are: (1) move $m to some completely different subfield ($z public note, $t copy number? Little misleading), or (2) have 2 instances of $o in some of my 952 fields, although I am not sure how this will render, or even whether Koha will accept this (is $o repeatable??) I hope I have been clear. Please let me know if you have ideas. I am running Koha v. 3.0001005 and I attach a sample record (with most edits made) below. Note that this record contains two 952s because it is a 2 volume set, as well as the $m's. =LDR 01105cam 2200301 i 4500 =001 \\\74075531\//r952 =003 DLC =005 19950918112125.9 =008 750501s1975\\\\nyua\\\\\b\\\\00010\eng\\ =010 \\$a 74075531 //r952 =020 \\$a091384800X =040 \\$aDLC$cDLC$dDLC =043 \\$an-us--- =050 \\$aQH76$b.E36 =082 00$a333.7/2 =100 10$aEgler, Frank Edwin,$d1911- =245 14$aThe plight of the rightofway domain :$bvictim of vandalism /$cby Frank E.
