'Straight from the horse's mouth', as they say. Edward Ruppelt was the first head of the U.S. Air Force's Project Blue Book, the official project initiated to investigate UFO reports beginning in 1952. This report from 1956 takes us inside these initial investigations, separates fact from fiction, and gives insight into who, when, where, and how sightings were reported and researched in open-minded fashion (for which Ruppelt was renowned), rather than in the typical hushed and secretive (and censored) manner most often associated with government and military reports which are released to the public.

Dozens of specific sightings are recounted, although hundreds more had come pouring...

The Woods Hutchinson Health Series, A HANDBOOK OF HEALTH
By Woods Hutchinson, A. M., M. D. PREFACE Looking upon the human body from the physical point of view as the most perfect, most ingeniously economical, and most beautiful of living machines, the author has attempted to write a little handbook of practical instruction for the running of it. And seeing that, like other machines, it derives the whole of its energy from its fuel, the subject of foods--their properties, uses, and methods of preparation--has been gone into with unusual care. An adequate supply of clean-burning food-fuel for the human engine is so absolutely fundamental both for health and for efficiency--we are so lite...

Save the Girls is an 1880 American anti-white-slavery book by reformed gambler Mason Long. In it, the author crusades against the social evil of prostitution by presenting a series of pathetic portraits of young women from various social classes who are brought low by such temptations of city life as the theater, the racecourse, and street flirtations. Included are vignettes of vice like "The Evils of Dancing - Sad Results of a Public Ball," in which innocent Marie, out for a good time, falls prey to the type of 'sporting men' who prowl such events in search of a partner for more than just The Glide or the Boston Dip.

One man's opinion of woman in 1894. Charles Harper believes in the superiority of the male sex and the subordination of the female. He paints an entire gender with the same brush. He believes all women to be identical in mind (illogical) and body (knock-kneed) and vastly inferior to the male. He presents 'facts' to support his opinions:
"Woman's Mission is Submission"
"for woman has ever been the immoral sex"
"how truly like nature their tongues say 'No,' when their hearts throb 'Yes, yes!'"
"She will have to develop very greatly before she becomes the equal of man, either in mind or muscle"
"Woman is altogether different from and inferior to man: narrow-...

The way we feel about another person, or about objects, is often bound up in associations that have no direct connection with the person or object at all. Often, what we call a "change of heart" comes about sheerly from a change in the many associations which make up our present viewpoint. Now, suppose that these associations could be altered artificially, at the option of the person who was in charge of the process.... (from the Blurb )

AMUSEMENTS IN MATHEMATICS
by HENRY ERNEST DUDENEY
PREFACE
In issuing this volume of my Mathematical Puzzles, of which some have appeared in periodicals and others are given here for the first time, I must acknowledge the encouragement that I have received from many unknown correspondents, at home and abroad, who have expressed a desire to have the problems in a collected form, with some of the solutions given at greater length than is possible in magazines and newspapers. Though I have included a few old puzzles that have interested the world for generations, where I felt that there was something new to be said about them, the problems are in the main original. It is true that so...

Published in 1911 as part of the "Harper's Library of Living Thought," this volume presents an introduction to the chemistry of cells in the context of plant physiology and gives an interesting overview of the field of biochemistry and related sciences at the time. The author, Frederick Czapek, was a Czech botanist and professor of Plant Physiology at the University of Prague. He is perhaps best known for his two-volume work on Plant Physiology, "Biochemie der Pflanzen" and for Czapek solution agar or Czapek-Dox medium, a culture medium for cultivation of fungus species such as Aspergillus and Penicillium molds.

Here are two early stories by the well known SF Author Robert Silverberg. The Happy Unfortunate was published first in Amazing Stories in 1957 and explores the angst caused when the human race reaches into space but at the cost of needing to breed a new species; specialized 'spacers' who can withstand the tremendous rigors of acceleration. The Hunted Heroes was published in Amazing stories a year earlier, in 1956. It is a futuristic story that holds great hope for the resilience of the human race after the war destroys most of the world.

The Flying Saucers are Real is a book that investigates numerous encounters between USAF fighters, personnel, and other aircraft, and UFOs between 1947 and 1950. Keyhoe contended that the Air Force was actively investigating these cases of close encounter, with a policy of concealing their existence from the public until 1949. He stated that this policy was then replaced by one of cautious, progressive revelation. Keyhoe further stated that Earth had been visited by extraterrestrials for two centuries, with the frequency of these visits increasing sharply after the first atomic weapon test in 1945. Citing anecdotal evidence, he intimated the Air Force may have attained and adapted some as...
