Proposal: 1 - Add a new system preference "Z39ResponderUnavailable" 2 - Similar to 'OpacHiddenItems' this will accept a list of column/value pairs 3 - Update Koha::Z3950Responder::Session::add_item_status to check the preference and mark item as unavailable 4 - Item status message will be pulled from Z3950_STATUS authorized value list
