Washington National Records Center (WNRC)

From www.archives.gov:

The Washington National Records Center (WNRC) provides reference services for records of Federal agencies located in the District of Columbia, Maryland, Virginia, and West Virginia.

WNRC is the first stop for records after they are no longer actively used by the Federal agency of origin. WNRC also has records of Federal Courts located in the District of Columbia and serves the Armed Forces worldwide.

Agency records stay at the WNRC, where they are tracked through an automated database, until they are either destroyed through recycling or accepted by NARA as permanent records. Access to most records stored at the facility is controlled by the agency of origin, however court records are open to the public.
