See: Bug 37702 comment 2 Bug 39561 comment 3 One suggestion is that we should only apply the duplicate check to other fast add records. I suggest maybe we need something more. The situation here seems to be that a book has come to the desk and needs to be issued. It is a new copy of an existing title. The librarian with fast add enters title and author and a duplicate is found. I think there should be an option to add the new duplicate, but have it linked to the original record. I am thinking while we want the circulation to go smoothly, we also want an easy way for catalogers to see that there is a fast add duplicate of an existing record that likely needs to be merged
