Can someone please point me to more info about normalization rules in the context of defining a matching rule in Koha? Scenario: Our set of books currently in Koha was imported from Marc that we created using MarcEdit (mapping from an Excel spreadsheet). As a result our Marc information is likely "not as good" as that of LOC for any given book. So now we are trying to "overlay", or "overwrite" as many of the biblio records in our Koha database with (hopefully) "better" MARC records from LOC (or wherever). Problem: When I do a bulk z39.50 lookup on ISBN numbers (using MarcEdit), the ISBN numbers I receive from LOC often contain trailing text (like "paperback", or ":"). When I stage these records and try to match the staged records on ISBN in Koha this trailing text prevents many matches. I am assuming that it is the job of some sort of normalization routine to force a match, however I am not able to find any documentation or examples describing how one would define his/her own normalization routine. Can someone please provide an example? Thanks, Pete. -- View this message in context: http://koha.1045719.n5.nabble.com/normalization-rule-defining-a-matching-rul...
