But I am alone, and need only to close a contact for the office lights to dim. As I settle back in my wheelchair, the Prime Radiant activates, its equations spreading around me in three-dimensional splendor. To the untrained eye, this multicolored swirl would be merely a jumble of shapes and numbers, but for me—and Yugo, Wanda, Gaal—this is psychohistory, come to life.
What I see before me, around me, is the future of humanity. Thirty thousand years of potential chaos, compressed into a single millennium …
That patch, glowing more strongly day by day, is the Terminus equation. And there—skewed beyond repair—are the Trantor figures. But I can see … yes, softly beaming, a steady light of hope … Star’s End!
This—this—was my life’s work. My past—humanity’s future. Foundation. So beautiful, so alive. And nothing can …
Dors!
SELDON, HARI— … found dead, slumped over his desk in his office at Streeling University in 12,069 G.E. (1 F.E.). Apparently Seldon had been working up to his last moments on psychohistorical equations; his activated Prime Radiant was discovered clutched in his hand.…
According to Seldon’s instructions, the instrument was shipped to his colleague Gaal Dornick who had recently emigrated to Terminus.…
Seldon’s body was jettisoned into space, also in accordance with instructions he’d left. The official memorial service on Trantor was simple, though well attended. It is worth noting that Seldon’s old friend former First Minister Eto Demerzel attended the event. Demerzel had not been seen since his mysterious disappearance immediately following the Joranumite Conspiracy during the reign of Emperor Cleon I. Attempts by the Commission of Public Safety to locate Demerzel in the days following the Seldon memorial proved to be unsuccessful.…
Wanda Seldon, Hari Seldon’s granddaughter, did not attend the ceremony. It was rumored that she was grief-stricken and had refused all public appearances. To this day, her whereabouts from then on remain unknown.…
It has been said that Hari Seldon left this life as he lived it, for he died with the future he created unfolding all around him.…

THE FOUNDATION NOVELS
Prelude to Foundation
It is the year 12,020 G.E. and Emperor Cleon I sits uneasily on the Imperial throne of Trantor. Here in the great multidomed capital of the Galactic Empire, forty 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.
Hari Seldon has come to Trantor to deliver his paper on psychohistory, his remarkable theory of prediction. Little does the young Outworld mathematician know that he has already sealed his fate and the fate of humanity. For Hari possesses the prophetic power that makes him the most wanted man in the Empire … the man who holds the key to the future—an apocalyptic power to be known forever after as the Foundation.
Foundation
For twelve thousand years the Galactic Empire has ruled supreme. Now it is dying. Only Hari Seldon, creator of the revolutionary science of psychohistory, can see into the future—a dark age of ignorance, barbarism, and warfare that will last thirty thousand years. To preserve knowledge and save mankind, 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.
But soon the fledgling Foundation finds itself at the mercy of corrupt warlords rising in the wake of the receding Empire. And mankind’s last best hope is faced with an agonizing choice: submit to the barbarians and live as slaves—or take a stand for freedom and risk total destruction.
Foundation and Empire
Led by its founding father, the great psychohistorian Hari Seldon, and taking advantage of its superior science and technology, the Foundation has survived the greed and barbarism of its neighboring warrior-planets. Yet now it must face the Empire—still the mightiest force in the Galaxy even in its death throes. When an ambitious general determined to restore the Empire’s glory turns the vast Imperial fleet toward the Foundation, the only hope for the small planet of scholars and scientists lies in the prophecies of Hari Seldon.
But not even Hari Seldon could have predicted the birth of the extraordinary creature called the Mule—a mutant intelligence with a power greater than a dozen battle fleets … a power that could turn the strongest-willed human into an obedient slave.
Second Foundation
After years of struggle, the Foundation lies in ruins—destroyed by the mutant mind power of the Mule. But it is rumored that there is a Second Foundation hidden somewhere at the end of the Galaxy, established to preserve the knowledge of mankind through the long centuries of barbarism. The Mule has failed to find it the first time—but now he is certain he knows where it lies.
The fate of the Foundation now rests on young Arcadia Darell, only fourteen 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.
Foundation’s Edge
At last, the costly and bitter war between the two Foundations has come to an end. The scientists of the First Foundation have proved victorious; and now they return to Hari Seldon’s long-established plan to build a new Empire on the ruins of the old. But rumors persist that the Second Foundation is not destroyed after all—and that its still-defiant survivors are preparing their revenge. Now two exiled citizens of the Foundation—a renegade Councilman and a doddering historian—set out in search of the mythical planet Earth … and proof that the Second Foundation still exists.
Meanwhile, someone—or something—outside both Foundations seems to be orchestrating events to suit its own ominous purpose. Soon representatives of both the First and Second Foundations will find themselves racing toward a mysterious world called Gaia and a final, shocking destiny at the very end of the universe.
Foundation and Earth
Centuries after the fall of the First Galactic Empire, Mankind’s destiny lies in the hands of Golan Trevize, former Councilman of the First Foundation. Reluctantly, he had chosen the mental unity of Galaxia as the only alternative to a future of unending chaos.
But Mankind as massmind is not an idea Trevize is comfortable with. So he sets off instead on a journey in search of humanity’s legendary home�
��fabled Earth—hoping to find a solution to his dilemma there.
Yet Earth has been lost for thousands of years, and no one can say exactly where it is—or if, indeed, it exists at all. More important, Trevize begins to suspect that he might not like the answers he finds.…
Forward the Foundation
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.
Among those seeking to turn psychohistory into the greatest weapon known to man are a populist political demagogue, the weak-willed Emperor Cleon I, and a ruthless militaristic general. In his last act of service to humankind, Hari Seldon must somehow save his life’s work from their grasp as he searches for its true heirs—a search that begins with his own granddaughter and the dream of a new Foundation.
THE ROBOT NOVELS
I, Robot
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 the scientists who invented the earliest robots weren’t content that their creations should remain programmed helpers, companions, and semi-sentient worker-machines. And soon the robots themselves, aware of their own intelligence, power, and humanity, weren’t either.
As humans and robots struggle to survive together—and sometimes against each other—on Earth and in space the future of both hangs in the balance. Here human men and women confront robots gone mad, telepathic robots, robot politicians, and vast robotic intelligences that may already secretly control the world. And both are asking the same questions: What is human? and Is humanity obsolete?
The Caves of Steel
A millennium into the future two advances 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 overpopulated Earth, New York City police detective Elijah Baley had little love for either the arrogant Spacers or their robotic companions. But when a prominent Spacer is murdered under mysterious circumstances, Baley is ordered to the Outer Worlds to help track down the killer.
The relationship between Lije and his Spacer superiors, who distrusted all Earthmen, was strained from the start. Then he learned that they had assigned him a partner: R. Daneel Olivaw. Worst of all was that the “R” stood for robot—and his positronic partner was made in the image and likeness of the murder victim!
The Naked Sun
On the beautiful Outer World planet of Solaria, a handful of human colonists lead a hermitlike existence, their every need attended 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.
The victim had been so reclusive that he appeared to his associates only through holographic projection. Yet someone had gotten close enough to bludgeon him to death while his robots looked on. Now Baley and Olivaw are faced with two clear impossibilities: Either the Solarian was killed by one of his robots—unthinkable under the Laws of Robotics—or he was killed by the woman who loved him so much that she never came into his presence!
The Robots of Dawn
Detective Elijah Baley 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.
THE STAND-ALONES
Fantastic Voyage
Four men and one woman are reduced to a microscopic fraction of their original size. Boarding a miniaturized atomic sub, they are injected into a dying man’s carotid artery. Passing through the heart and entering the inner ear, where even the slightest sound would destroy them, they battle relentlessly into the cranium. Their objective: to reach a blood clot and destroy it with the piercing rays of a laser. At stake: the fate of the entire world.
The Gods Themselves
In the twenty-second century, Earth obtains limitless, free energy from a source science little understands: an exchange between Earth and a parallel universe, using a process devised by the aliens. But even free energy has a price. The transference process will eventually lead to the destruction of Earth’s sun—and of Earth itself.
Only a few know the terrifying truth—an outcast Earth scientist, a rebellious alien inhabitant of a dying planet, and a lunar-born human intuitionist who senses the immanent annihilation of the Sun. They know the truth—but who will listen? They have foreseen the cost of abundant energy—but who will believe? These few beings, human and alien, hold the key to the Earth’s survival—if they can get anyone to pay attention.
Nemesis
In the twenty-third century, pioneers have escaped the crowded Earth for life in self-sustaining orbital colonies. One of the colonies, Rotor, has broken away from the solar system to create its own renegade utopia around an unknown red star two light-years from Earth: a star named Nemesis.
Now a fifteen-year-old Rotorian girl has learned of the dire threat that Nemesis poses to the Earth’s people—but she is prevented from warning them. Soon she will realize that Nemesis endangers Rotor as well. And soon it will be up to her alone to save both Earth and Rotor as—drawn inexorably by Nemesis, the death star—they hurtle toward certain disaster.
Nightfall (written with Robert Silverberg)
On a planet with six suns, night is about to fall for the first time in two thousand years.
The planet Kalgash is on the brink of chaos—but only a handful of people realize it. Kalgash knows only the perpetual light of day; for more than two millennia, some combination of its six suns has lit up the sky. But twilight is now gathering. Soon the suns will set all at once—and the terrifying splendor of Nightfall will call forth a madness that signals the end of civilization.
Isaac Asimov’s short story “Nightfall” first appeared in 1941. It has since become recognized as a classic, its author a legend. But the short story isn’t the whole story. Now Dr. Asimov has teamed up with multiple Hugo and Nebula Award winner Robert Silverberg to explore and expand one of the most awe-inspiring concepts in the history of science fiction.
In this novel, you will witness Nightfall—and much more.
You will learn what happens at Daybreak.
