They mustn't harm a human being, they must obey human orders, and they must protect their own existence...but only so long as that doesn't violate rules one and two. With these Three Laws of Robotics, humanity embarked on a bold new era of evolution that would open up enormous possibilities, and unforeseen risks.

For 12,000 years the Galactic Empire has ruled supreme. Now it is dying. But only Hari Seldon, creator of the revolutionary science of psychohistory, can see into the future - to a dark age of ignorance, barbarism, and warfare that will last thirty thousand years. To preserve knowledge and save humankind, Seldon gathers the best minds in the Empire - both scientists and scholars - and brings them to a bleak planet at the edge of the galaxy to serve as a beacon of hope for future generations. He calls his sanctuary the Foundation.

The second novel in Isaac Asimov’s classic science-fiction masterpiece, the Foundation series. Led by its founding father, the psychohistorian Hari Seldon, and utilizing science and technology, the Foundation survived the greed and barbarism of its neighboring warrior-planets. Now cleverness and courage may not be enough. For the Empire - the mightiest force in the Galaxy - is even more dangerous in its death throes. Even worse, a mysterious entity called the Mule has appeared with powers beyond anything humanly conceivable. Who - or what - is the Mule?

After years of bitter struggle, Trantor had at last completed its work - its Galactic Empire ruled all 200 million planets of the Galaxy...all but one. On a backward planet called Earth were those who nurtured bitter dreams of a mythical, half-remembered past when the planet was humanity’s only home. The other worlds despised it or merely patronized it - until a man from the past miraculously stepped through a time fault that spanned a millennium, living proof of Earth’s most preposterous claims.

The fate of the Foundation rests on young Arcadia Darell, only 14 years old and burdened with a terrible secret. As its scientists gird for a final showdown with the Mule, the survivors of the First Foundation begin their desperate search. They too want the Second Foundation destroyed, before it destroys them.

It is the year 12,020 GE and Emperor Cleon I sits uneasily on the Imperial throne of Trantor. Here in the great multidomed capital of the Galactic Empire, 40 billion people have created a civilization of unimaginable technological and cultural complexity. Yet Cleon knows there are those who would see him fall - those whom he would destroy if only he could read the future.

The Eternals, the ruling class of the Future, had the power of life and death not only over every human being but over the very centuries into which they were born. Past, Present, and Future could be created or destroyed at will. You had to be special to become an Eternal. Andrew Harlan was special. Until he committed the one unforgivable sin - falling in love. Eternals weren’t supposed to have feelings. But Andrew could not deny the sensations that were struggling within him. He knew he could not keep this secret forever. And so he began to plan his escape.

Detective Elijah Baiey is called to the Spacer world Aurora to solve a bizarre case of roboticide. The prime suspect is a gifted roboticist who had the means, the motive, and the opportunity to commit the crime. There's only one catch: Baley and his positronic partner, R. Daneel Olivaw, must prove the man innocent. For in a case of political intrigue and love between woman and robot gone tragically wrong, there's more at stake than simple justice. This time Baley's career, his life, and Earth's right to pioneer the Galaxy lie in the delicate balance.

As Hari Seldon struggles to perfect his revolutionary theory of psychohistory and ensure a place for humanity among the stars, the great Galactic Empire totters on the brink of apocalyptic collapse. Caught in the maelstrom are Seldon and all he holds dear, pawns in the struggle for dominance. Whoever can control Seldon will control psychohistory - and with it the future of the galaxy. 

A millennium into the future, two advancements have altered the course of human history: the colonization of the Galaxy and the creation of the positronic brain. On the beautiful Outer World planet of Solaria, a handful of human colonists lead a hermit-like existence, their every need attended to by their faithful robot servants. To this strange and provocative planet comes Detective Elijah Baley, sent from the streets of New York with his positronic partner, the robot R. Daneel Olivaw, to solve an incredible murder that has rocked Solaria to its foundations.

A millennium into the future two advancements have altered the course of human history: the colonization of the galaxy and the creation of the positronic brain. Isaac Asimov's Robot novels chronicle the unlikely partnership between a New York City detective and a humanoid robot who must learn to work together. Like most people left behind on an over-populated Earth, New York City police detective Elijah Baley had little love for either the arrogant Spacers or their robotic companions.

Golan Trevize, former councilman of the First Foundation, has chosen the future, and it is Gaia. A superorganism, Gaia is a holistic planet with a common consciousness so intensely united that every dewdrop, every pebble, every being, can speak for all - and feel for all. It is a realm in which privacy is not only undesirable, it is incomprehensible. But is it the right choice for the destiny of mankind? While Trevize feels it is, that is not enough. He must know.  

Trantor had extended its rule over half the Galaxy, but the other half defied its authority, defending their corrupt fiefdoms with violence and repression. On the planet Florina, the natives labored as slaves for their arrogant masters on nearby Sark. But now both worlds were hurtling toward a cataclysmic doom, and only one man knew the truth - a slave unaware of the secret knowledge locked inside his own brain. Rik had once been a prominent scientist until a psychic probe erased all memories of his past. Now he was a humble laborer in the kyrt mills of Florina.

Ignition! is the story of the search for a rocket propellant which could be trusted to take man into space. This search was a hazardous enterprise carried out by rival labs who worked against the known laws of nature, with no guarantee of success or safety. John Drury Clark writes with irreverent and eyewitness immediacy about the development of the explosive fuels strong enough to negate the relentless restraints of gravity. The resulting volume is as much a memoir as a work of history, sharing a behind-the-scenes view of an enterprise that eventually took men to the moon.

The opening episode begins on Trantor, capital of the Galactic Empire, with the meeting of Seldon and Dornick, their trial, and their exile to Terminus. The action then jumps forward 50 years, to the first Seldon Crisis, where the repercussions of the recent independence of the Four Kingdoms of the Periphery are being felt on Terminus, and are handled by the first Mayor, Salvor Hardin....

His name was Biron Farrill and he was a student at the University of Earth. A native of one of the helpless Nebular Kingdoms, he saw his home world conquered and controlled by the planet Tyrann - a ruthless, barbaric Empire that was building a dynasty of cruelty and domination among the stars. Farrill’s own father had been executed for trying to resist the Tyrann dictatorship and now someone was trying to kill Biron. But why? His only hope for survival lay in fleeing Earth and joining the rebellion that was rumored to be forming somewhere in the Kingdoms.
