It would be nice if when using isbn as a match point it normalized the ISBN first. Now if one isbn ends in (pbk) and the other doesn't - but they're both the same number it doesn't match them and imports duplicates.

I am not sure how it works - but there is a field for a normalization rule in the staff interface. So perhaps there is some 'hidden' feature that would allow doing this?
Business::ISBN has functions to do stuff like that.
according to the manual: Koha only has one 'Normalization rule' that removes extra characters such as commas and semicolons. The value you enter in this field is irrelevant to the normalization process.
What's a good starting point for getting this fixed? I'd love to help with this project.
