The list author says: "The following is a list of the best of the best with respect to the honest, scientific study of the UFO phenomenon. These are books that stick close to the facts, keep speculation to a minimum, and often offer unique expertise or analysis in their respected specialized fields of expertise.
Taken as a whole, they provide the most comprehensive, well-rounded view of UFO's to date. As academic as it gets."
"The single most important book on the subject. An in-depth, unbiased analysis of the aversion of the UFO subject by mainstream media. The history of seemingly honest journalists on government payroll to promote war time propaganda and other issues of national security is evaluated to provide context to the discussion."
"Historians perspective. The (on going) UFO's and the National Security State series AS A WHOLE by Richard Dolan is absolute mandatory reading for anyone interested in undertaking a legitimate study of the phenomenon, past and present. As thorough and meticulous as they come."
"About as conservative yet convincing as they come. An assortment of a select few of the best UFO cases in existence, written in the words of the high ranking officials that were witness to the events. Highly acclaimed and well received by the media (a rarity). A true milestone in UFOlogical literature."
"Significant academic book that provides qualified scientific analsysis of several baffling UFO cases involving physical evidence. If anyone says there is no physical evidence for the existance of UFOs, hand them this book."
"Hynek's respectable scientific analysis of the UFO phenomenon at the peak of his transformation from hardline skeptic to cautious UFO advocate. An important scientific expose from perhaps the most famous astronomer/UFO researcher in history."
"A comprehensive compilation of CE-5 case summaries. (CE-5 are cases where UFOs or occupants responded to signals from the witness[es]) Dr. Richard Haines is a well respected, former NASA research scientist specializing in experimental psychology. **Not a smooth read. Strictly reference material.**"
"Covers the more controverisal sub-section of UFOlogy, but does so in a commendable, academic manner. Multiple authors, almost all of whom have unique academic perspectives on the matter. Highly credentialed work."
