A bulk upload of local titles into the ERM is a bit cumbersome and requires importing titles through Stage MARC records, creating a list from Biblio numbers of the imported titles, and adding the list into titles. It would be far simpler to have a direct link to Stage MARC records to pull the titles into Koha and the ERM. Perhaps similar to the process in Acquisitions.
