Do Androids Dream of Electric Sheep was first published in 1968. The novel tells the story of Rick Deckard and his quest to retire six Nexus-6 androids, the most advanced type, in 24 hours. The novel follows Deckard and a secondary character - John R. Isidore - through a futuristic San Francisco wasteland. The earth has been largely destroyed by the nuclear fallout of World War Terminus, most of the survivors of which have left for a new colony on Mars. Androids, who are built to be humans slaves on Mars, often escape back to earth where they must be killed because they are devoid of real life.
The novel did not gain a great deal of critical or commercial success until the book was adapted into a screenplay and shot as the movie Blade Runner , starring Harrison Ford. Dick, unfortunately, would not survive to see much of his work take on a second life in film, but today many of his works, including Do Androids Dream of Electric Sheep? , are considered classics of the science fiction genre. In 2005, Dick and his novel Electric Sheep were the first science fiction pieces to be anthologized in a Library of America volume.
