The original book The Matrix - Understanding Aspects of Planetary Power Structures (1988), was an outgrowth of previous work, an earlier 52-page analysis of UFO related literature that existed at the time (the so-called Krill Papers, available in Leading Edge Bound Volume #1). The paradigm of aliens, government and manipulation was then subject to a couple more years work, resulting in Matrix II: The Abduction and Manipulation of Humans Using Advanced Technology (1990/91), which should be considered the definitive work on UFO's, Aliens, Abductions and Apparent Interaction with planetary power structures and military.
