Government guards papers from public eye: More than 1 million pages of historical government documents — a stack taller than the U.S. Capitol — have been removed from public view since the September 2001 terror attacks, according to records obtained by The Associated Press. Some of the papers are more than a century old.
In some cases, entire file boxes were removed without significant review because the government's central record-keeping agency, the National Archives and Records Administration, did not have time for a more thorough audit. [...]
In all, archivists identified as many as 625 million pages that could have been affected under the security program. In their haste to remove potentially harmful documents from view, archives officials acknowledged many records were withdrawn that should be available.
The public can still request to see parts of withdrawn documents under the Freedom of Information Act and may in some cases be allowed to see whole files that were removed.
