While harvesting Koha records from the OAI-PMH interface, I found a series of records that can't be accessed using the OPAC interface. That is, the harvester finds a record with an identifier, say
that shows the complete record.
Trying to link to the OPAC using the biblionumber in the last part of the identifier, say
I get a 404 error.
I have yet to confirm this, but this might be related to the records being hidden in the OPAC view being leaked into OAI. In that case, I would expect the record to have a deleted status in OAI so that in can be removed from the harvesting results.
