Hi everyone, I have set up Koha for testing, however the database I have imported is four months old. My colleagues complain about it and want me to add new records from other library software for more thorough testing. I could re-import the whole database, however it`s not a good solution in the long run - we have another ILS that has to stay for a while, all cataloging is done in that ILS and it has to stay that way for a year or so. I can prepare a batch of new records for importing into Koha, however don`t know if the bulkmarcimport script could do the job the way I`d like: - reject biblios that already are in the DB and import item-specific fields only, connecting them to existing biblios; - import biblios that are not in the DB, along with items. In other words: I need to perform many partial imports and avoid biblio and item duplicates. Has anyone tried something like that? Is there any way to do it? Thanks for anyhelp! Regards, Tomasz.
