To restore deleted records, you need:
- The MMSID or PID for a single record. (The PID is a system number for an inventory entity. See Configuring Search Indexes.)
- A date range, user ID, or deletion job ID for a group of records deleted at the same time, by the same user, or in a single job.
...
- When restoring records deleted by a user, only records deleted by the last action performed by that user are restored.
- Restoring a bibliographic record restores all records that were deleted together with it, for example holdings and item records.
- Restoring an item record restores its higher level records, for example holdings and bibliographic records, but not other records that were under its associated bibliographic record.
