Flying Saucers are Real
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...

Raiders of the Universes
It was the 34th century and all five of the Federation of Planets around Sol were buzzing with their usual activity when the Raiders appeared. They were indeed Raiders of Universes because they had ravaged many systems before reaching Earth and showed no signs of slowing down in the least. Their weapons were invincible, their greed merciless and their natures completely alien. Indeed 'they' were from another dimension entirely. Eating up entire solar systems and planets, they slowed down just a bit when intelligent life was found on Earth...

A short pamphlet from WWI, a sequel of sorts to "Food Preparedness." It first describes basic nutrition and things to consider when choosing what foods to eat, then lists various foods and their amount of calories, carbohydrates, fats, proteins, water, and "ash". This was written before much was known about fat soluble vitamins or saturated vs. unsaturated fats.

Spacehounds of IPC
When the Inter-Planetary Corporation's (IPC) crack liner “IPV Arcturus” took off on a routine flight to Mars, it turned out to be the beginning of a unexpected and long voyage. There had been too many reports of errors in ship's flight positions from the Check Stations and brilliant physicist Dr. Percival (“Steve”) Stevens is aboard the Arcturus on a fact-finding mission to find out what's really happening, and hopefully save the honor of the brave pilots of the space-liner Arcturus from the desk-jockeys' in the Check Stations implications of imprecision - the nastiest insult you could cast at a ships pilot...
This is a sequel to The Skylark of Space. The novel concerns Richard Seaton and his allies who have encounters with aliens while fighting DuQuesne and the Fenachrone..
The Skylark of Space
The Skylark of Space is one of the earliest novels of interstellar travel and is considered a classic of pulp science fiction. Originally serialized in 1928 in the magazine Amazing Stories it is often categorized as the first literary space opera, complete with protagonists perfect in mind, body, and spirit, who fight against villains of absolute evil.
A team of space travelers are caught in a subspace accident which, up to now, no one has ever survived. But some of the survivors of the Procyon are not ordinary travelers. Their psi abilities allow them to see things before they happen. But will it be enough?Smith's story "Subspace Survivors" first appeared in the July 1960 issue of the magazine Astounding.
They were four of the greatest minds in the Universe: Two men, two women, lost in an experimental spaceship billions of parsecs from home. And as they mentally charted the Cosmos to find their way back to earth, their own loves and hates were as startling as the worlds they encountered.

Triplanetary, First in the Lensman Series
Triplanetary was first serialized in Amazing Stories in 1934. After the Lensman series became popular, Smith took his Triplanetary story and turned it into the first of the Lensman series, using it as a prequel to give the back story for the protaganists in the Lensmen series. He added 6 new chapters, doubling it in size and it's really a different book from the serialized novel, being published 14 years after the first. It was put into Gutenberg just last year. The novel covers several episodes in an eons-long eugenics project of the super-intelligences of the Arisia...
