Most of this duplication appears to be due to one library using a record that has a 10 digit ISBN, while another library used a record that has a 13 digit ISBN. I am sure that this is a problem many of you have encountered. I would like to pose a couple of questions to the group: First, is it your experience that Koha only matches on the first instance of an ISBN in the 020 field? Does the matching engine follow through and check the second 020 field for a matching ISBN? Second, would the development of a built in ISBN 10 to ISBN 13 converter in Koha matching reduce the number of record duplicates? My inclination is that it would. Thanks for your thoughts on this.
