Title from home page (viewed on April 21, 2011). "The Vault is our new electronic reading room, containing more than 2,000 documents that have been scanned from paper into digital copies so you can read them in the comfort of your home or office. Included here are more than 25 new files that have been released to the public but never added to this website; dozens of records previously posted on our site but removed as requests diminished; and files from our previous electronic reading room."
