Phi Beta Iota: Created by Robert Steele using an original citation analysis map from Dick Klavans. For more on what can be done to visualize citation analytics, see Maps of Science.

This chart is reproduced from Steele, ‘A Critical Evaluation', Fig.11, p.90, and in turn was taken from the CIA ‘Intelligence Successes and Failures Course', which has been discontinued. It also appears in ON INTELLIGENCE: Spies and Secrecy in an Open World (2000).
