10 March 2015
"This Archive is a complete collection of all documents that former NSA contractor Edward Snowden leaked in June 2013 to journalists Laura Poitras, Glenn Greenwald and Ewen MacAskill, and subsequently were published by news media, such as The Guardian, The New York Times, The Washington Post, Der Spiegel, Le Monde, El Mundo and The Intercept... The Archive also contains some documents that the U.S. Government has published which are helpful in understanding the leaked documents."
