Foundation

by Isaac Asimov

Prelude to Foundation
Hari Seldon is the man who laid the framework for the universe that came to be known as the Foundation. The long-awaited overture to the greatest science fiction series of all time, tells his story.
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 his true heirs—a search the begins with his own granddaughter and the dream of a new Foundation.
Foundation
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 future generations. He calls his sanctuary the Foundation.
Foundation and Empire
Although small and seemingly helpless, the Foundation has managed to survive against the greed of its neighboring warlords. But can it stand against the mighty power of the Empire, who has created a mutant man with the strength of a dozen battlefleets?
Second Foundation
Isaac Asimov's Foundation novels are one of the great masterworks of science fiction. As unsurpassed blend of nonstop action, daring ideas, and extensive world-building, they chronicle the struggle of a courageous group of men and women dedicated to preserving humanity's light in a galaxy plunged into a nightmare of ignorance and violence thirty thousand years long. 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 failed to find it the first time—but now he is certain he knows where it lies. The fate of the Foundation 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
Now, 498 years after its founding, the Foundation seemed to be following the Seldon Plan perfectly. Too perfectly. Now an impossible planet -- with impossible powers -- threatens to upset the Seldon Plan for good unless two men, sworn enemies, can work together to save it!
Foundation and Earth
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.
