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...

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...

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...

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 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...

When the long struggle for the enfranchisement of women is over, those who read the history of the movement will wonder at the blindness that led the Government of the day to obstinately resist so simple and obvious a measure of justice...

Uncontrolled, terribly violent Atomic Vortices are slowly destroying civilization on every human planet throughout the galaxy.

The tragedy triggers actions on his part that pit him one-on-one against the horrible vortices. Introducing "storm" Cloud as THE Vortex Blaster

“Doc” E.E. Smith pretty much invented the space opera genre, and Triplanetary is a good and well-known example. Physics, time, and politics never stand in the way of a plot that gallops ahead without letup. Having earned a PhD in chemical engineering, it’s understandable that the heroes of Smith’s story are all scientists. He didn’t want to be constrained by the limits of known science, however, so in his hands the electromagnetic spectrum becomes a raw material to be molded into ever-more amazing and lethal forms, and the speed of light is no bar to traveling through the interstellar void...
