However, records from other sources may still be protected by copyright or donor agreements. Executive Order 13526 directs originating agencies to declassify documents if possible before shipment to NARA for long-term storage, but NARA also stores some classified documents until they can be declassified. Its Information Security Oversight Office monitors and sets policy for the U.S. government's security classification system.
