The Five Disciplines of Intelligence Collection

"The Five Disciplines of Intelligence Collection fills a real need for a basic guide to the key intelligence disciplines.  It will be especially useful to intelligence practitioners and users of intelligence who need to know how intelligence is collected as well as the strengths and limitations of collection methods. Those who teach intelligence and national security issues, as I do, will find this book of immense utility. Lowenthal and Clark are extremely well qualified to compile this work because both are "insider" career intelligence professionals of the highest order who know their subject."

"Lowenthal and Clark have done us a major service with this edited work. By organizing it around the five major intelligence "disciplines" (human, signals, geospatial, measurement and signature, and open source), they show us how each has developed over time, in collecting and analyzing information, in support of U.S. national security. Though all the authors have technical expertise, the work is clearly written and is accessible to a wide variety of audiences, including students, novice analysts, policymakers, and even the public, who need to understand the strengths—and limitations—of intelligence. I highly recommend it."
