Declassification and Transparency


As NSA/CSS reviews records under the Freedom of Information Act or Mandatory Declassification Review provisions of Executive Order 13526, we will make the material available to the public via the NSA.gov website on the Internet. In addition, NSA/CSS periodically conducts "Special Topical Reviews" of categories of records, such as the Gulf of Tonkin, USS Liberty, UKUSA, and posts those records to this site. Lastly, in accordance with the federal Open Government initiative, we will identify subjects and records for which there is a general public interest. We will meet transparency goals by reviewing those records and including them on this web page.
