The Caves of Steel & The Rest Of The Robots ,Earth is Room Enough, The Robot of Dawn by Isaac Asimov

The Caves of Steel by Isaac Asimov

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. 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 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!

The Rest Of The Robots.

"The First Law of Robotics" A Robot may not injure a human being, or, through inaction, allow a human being to come to harm. So how could Robot MA-2 abandon its owner to certain death? How could Robot LNE-Pr break its masters with a blow of its fist? How could Robot EZ-27 turn against its owner and utterly ruin him? Meet Dr Susan Calvin, a robot psychologist, whose mission is to investigate robots and save humanity from destruction at their hands. Dangerous, Dazzling, Demonic...Here they come!" In these eight stories selected from his monumental classic The Rest of the Robots, Isaac Asimov displays the wit, drama and imagination that make his robot stories the most popular!

Earth is Room Enough

Earth Is Room Enough is a collection of fifteen short science fiction and fantasy stories and two pieces of comic verse by American writer Isaac Asimov, published in 1957. In his autobiography In Joy Still Felt, Asimov wrote, "I was still thinking of the remarks of reviewers such as George O. Smith... concerning my penchant for wandering over the Galaxy. I therefore picked stories that took place on Earth and called the book Earth Is Room Enough." The collection includes one story from the Robot series and four stories that feature or mention the fictional computer Multivac.

The Robots of Dawn

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.

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.
