Bug 17387 added new feature to restore deleted bibliographic records and items. The new tool does not show if the bibliographic record has child records / component parts or the fact that the listed record is a component part. The restore tool should show the component parts in connection with the host record and suggest that component parts are also restored when the host record is restored. The link between host and component part is recorded in component part's field 773 (MARC21). Field 773w contains the same value as host records field 001. The field 773t contains host record's title.
