The Preserving Machine

Well known as one of the major science fiction novelists of the decade, Philip K. Dick has concurrently built an almost “underground” reputation for his powerful, unpredictable short stories, novelettes and novellas.
Now, in this first major collection of Dick’s shorter work, you will find:
•    Robot psychiatrists activated by twenty-dollar coins
•    The Veterans of Unnatural Wars
•    Unicephalon 40-D, the computer President of the United States
•    Deceptive “toys” sent to Earth from Ganymede
•  •  • plus time-warps, homeostatic newspapers, “web-foots” and-“crows,” unseen alien creatures among us, half-human mutations: a gallery of sparkling invention in a book you’ll never forget.
