I'm paraphrasing a humorous remark made in Donoso, Julio. The Why of Things. United Kingdom, Athena Press, 2006, p. 134.

The El Teniente strike is well-covered in Bitar, Sergio, and Pizarro, Crisóstomo. La caída de Allende y la huelga de El Teniente: lecciones de la historia. Chile, Ediciones del Ornitorrinco, 1986; but also in Vergara, Angela. Copper Workers, International Business, and Domestic Politics in Cold War Chile. Pennsylvania State University Press, 2010.

In addition to Beer’s own works, a good account of the role played by The Quantified Flow Chart is to be found in Schwember, Hermann. "Cybernetics in Government: Experience With New Tools for Management in Chile 1971–1973." Concepts and Tools of Computer-assisted Policy Analysis, 1977, pp. 79–138. Available here.

Monica Gonzalez discusses that initial collaboration in May 1973 at the Hotel San Martín of Viña del Mar. See González, Mónica. La conjura: los mil y un dias del golpe. Editorial Catalonia, 2013, p. 175. Juan Gabriel Valdes, in Pinochet’s Economists, argues that these collaborations started as early as late 1972.

The literature on America’s involvement in Guatemala is voluminous, but Gleijeses, Piero. Shattered Hope: The Guatemalan Revolution and the United States, 1944-1954. United States, Princeton University Press, 2021; Schlesinger, Stephen, and Kinzer, Stephen. Bitter Fruit: The Story of the American Coup in Guatemala, Revised and Expanded. United Kingdom, Harvard University Press, 2020; and Cullather, Nick. Secret History, Second Edition: The CIA’s Classified Account of Its Operations in Guatemala, 1952-1954. United States, Stanford University Press, 2006 remain indispensable sources. David Philips' own memoirs are an interesting read. A recent investigative project focusing specifically on that propaganda radio operation covers some new ground: Snow, Sylvia Brindis & Snow, Shane.
