All, We've migrated data and now want to re-migrate with more accurate mapping of records/items. (We're learning more how to use Marc tags/fields daily!) Koha admin interface seems to only allow re-migration thru a matching of ISBN/ISSN. From my limited knowledge, I'm thinking it would be helpful to have additional matching fields for a re-import. Preferably *required* fields/tags, unlike ISBN/ISSN. Given that this is not an option, I'm considering whether there is a way from my Windows XP client to edit the MySQL tables hosted on our Koha Linux server. Could I view, edit, and delete Marc records and Koha 952 items this way? Might the GUI be this one: http://dev.mysql.com/downloads/gui-tools/5.0.html? Another related issue I've recently come across is that I don't think I can use MarcEdit to work with existing records until we've entered ISBN from scratch?! Maybe I should assign bogus, unique ISBN as a workaround in order to move records in and out of Koha? Thanks, Nelson Koha Enthusiast Implementing a union catalogue in Cape Town, South Africa
