Note: • Publisher's Note: This novel has a complicated history. It was first published in magazine form in 1964, under the title The Unteleported Man. For its book publication, in 1966, Philip Dick wrote a further 30,000 words, but in the event this extra material was not used. The published book was the same as the magazine version. Many years later, Dick reread the unpublished material and arranged for publication in the USA of the complete edition, with extensive revisions. Then he died, suddenly and tragically, in 1982. At the time there was no evidence that he had made the intended revisions, and so the novel was reissued in 1983 in the USA in its full 1966 version, with gaps in the text where four manuscript pages had gone missing during the long years in storage. Then, in November 1983, while British publication was being arranged, Dick's literary executor found among the author's papers his revised and retitled typescript. It is this version which is published here for the first time. Two gaps, each of one manuscript page, still remained, and for this edition John Sladek—an author Dick greatly admired—has written short linking passages to create a continuous narrative. For the benefit of literary detectives, Sladek's contributions are to be found on pp. 143 and 168-9. [from page 199 of the 1984 Gollancz edition] • Dick's original "missing pages" text for both of these expanded versions was then discovered and published in 1985 in the Philip K. Dick Society Newsletter #8. In 2004, the novel was reprinted in the USA using Dick's later revised "Lies, Inc." version of the text, and corrected for the first time to include the "missing pages" text rather than Sladek's bridging text.
