Everyman's Library: Foundation Trilogy

It is the story of the Galactic Empire, crumbling after twelve thousand years of rule. And it is the particular story of psycho-historian Hari Seldon, the only man who can see the horrors the future has in store: a dark age of ignorance, barbarism and violence that will last for thirty thousand years. Gathering together a band of courageous men and women, Seldon leads them to a hidden location at the edge of the galaxy where he hopes they can preserve human knowledge and wisdom against all who would destroy them.
