"Through Freedom of Information Act requests, and other avenues of declassification, the National Security Archive has been able to compile a collection of declassified records that shed light on events in Chile between 1970 and 1976."
"President Clinton had directed the Department of State to identify documents that would shed light on human rights abuses, terrorism, and other acts of political violence prior to, and during, the Pinochet era in Chile. This collection was the culmination of a government-wide effort resulting in the release of over 23,000 documents concerning Chile from 1968-1991 and posted to the Department of State FOIA website. This collection consists of documents produced by the CIA, DOD, NARA, NSC, FBI, DOJ, and the Department of State. Some information has been redacted to protect the privacy of individuals, sensitive law enforcement information, intelligence sources and methods, and other national security interests. WARNING: GRAPHIC MATERIAL INCLUDED."
An independent non-governmental research institute and library located at The George Washington University, the Archive collects and publishes declassified documents obtained through the Freedom of Information Act. The Archive also serves as a repository of government records on a wide range of topics pertaining to the national security, foreign, intelligence, and economic policies of the United States. Some of these items are accessible online for free.
