Parenthesis have been a problem when matching up ISBNs if you were using the Amazon plug in. I used MarcEdit and would search and destroy each comment that went with ISBNs. I hope this helps.

An expansion of Pete's email below; we have a major problem using "Normalization Rules" and "Normalization Checks" at <http://koha-admin/cgi-bin/koha/admin/matching-rules.pl?op=edit_matching_rule&matcher_id=1> to compare our biblio records with those of LoC (Library of Congress) for staged records.
Please note that we have searched the Koha docs; if this is a bug, please advise.
Take the following examples:
LoC ... 020 // $a 9004158634 (hbk. : alk. paper) Ours ... 020 // $a 9004158634
LoC ... 020 // $a 0870213601 : $c $22.95 Ours ... 020 // $a 0870213601
Koha does *not* match these. (the paranthetical comment in the first example appears "legal" under MARC; the colon in the second appears to be contrary to MARC definitions.)
The Koha admin page above gives two possibilities: (a) defining the "Normalization rule:" for the matchpoint (this appears to be matcher.pm which looks for ISBN and the date field in 008), or (b) adding a "match check" which might add flexibility. We have played unsuccessfully with these for a few days now.
Questions: Is there some documentation on this anywhere? If not, has anyone here got a solution?
Thanks in advance,
Paul Tired old sys-admin (now getting slightly frustrated)

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?
