1. To avoid a lengthy declassification review, this chapter relies on previously released sources to outline the evolution of the Foreign Relations series in the 1990s. Although unreleased Department of State records contain much more detailed information about the implementation of the FRUS statute, the formation of the High Level Panel, the evolving relationship between the CIA and HO, and efforts to modernize the Foreign Relations series for the Internet era, published sources provide an accurate description of FRUS in the 1990s. The most useful released sources are HAC meeting notes at Department of State, Office of the Historian website, http://history.state.gov/about/hac/meeting-notes and HAC reports at Federation of American Scientists, Project on Government Secrecy website, http://www.fas.org/sgp/advisory/state/index.html.
