For twelve thousand 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 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 a 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. Mankind's last best hope is faced with an agonizing choice: submit to the barbarians and be overrun -- or fight them and be destroyed.

The three laws of Robotics: 1) A robot may not injure a human being or, through inaction, allow a human being to come to harm 2) A robot must obey orders givein to it by human beings except where such orders would conflict with the First Law. 3) A robot must protect its own existence as long as such protection does not conflict with the First or Second Law. With these three, simple directives, Isaac Asimov changed our perception of robots forever when he formulated the laws governing their behavior. In I, Robot, Asimov chronicles the development of the robot through a series of interlinked stories: from its primitive origins in the present to its ultimate perfection in the not-so-distant future--a future in which humanity itself may be rendered obsolete. Here are stories of robots gone mad, of mind-read robots, and robots with a sense of humor. Of robot politicians, and robots who secretly run the world--all told with the dramatic blend of science fact and science fiction that has become Asmiov's trademark.

Although small and seemingly helpless, the Foundation had managed to survive against the greed of its neighboring warlords. But could it stand against the mighty power of the Empire, who had created a mutant man with the strength of a dozen battlefleets...?

The fifth novel in Asimov's popular Foundation series opens with second thoughts. Councilman Golan Trevize is wondering if he was right to choose a collective mind as the best possible future for humanity over the anarchy of contentious individuals, nations and planets. To test his conclusion, he decides he must know the past and goes in search of legendary Earth, all references to which have been erased from galactic libraries. The societies encountered along the way become arguing points in a book-long colloquy about man's fate, conducted by Trevize and traveling companion Bliss, who is part of the first world/mind, Gaia. From the Paperback edition.

At last, the costly and bitter war between the two Foundations had come to an end. The scientists of the First Foundation had 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!

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.

The relationship between Life 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!

One moment Joseph Schwartz is a happily retired tailor in Chicago, 1949. The next he's a helpless stranger on Earth during the heyday of the first Galactic Empire. Earth, as he soon learns, is a backwater, just a pebble in the sky, despised by all the other 200 million planets of the Empire because its people dare to claim it's the original home of man. And Earth is poor, with great areas of radioactivity ruining much of its soil—so poor that everyone is sentenced to death at the age of sixty. Joseph Schwartz is sixty-two. This is young Isaac Asimov's first novel, full of wonders and ideas, the book that launched the novels of the Galactic Empire, culminating in the Foundation series. This is Golden Age SF at its finest.
