For the record: The National Archives and Records Administration (NARA) keeps up to 3% of all materials deemed important enough to preserve during the course of conducting US federal government business. A federal agency, NARA preserves, maintains, and provides access to documents that record important events in US history. To protect archives (including letters, memos, reports, and photographs documenting citizens' rights, federal officials' actions, and national experiences), NARA stores them in acid-free folders and boxes in dark spaces with consistent temperature and humidity. Some 95% of them are declassified. Created in 1934, NARA has offices spanning some 20 states and Washington, DC.
