Cantata-140
The first seven chapters of Philip K. Dick's The Crack in Space were first published as Cantata-140 in Fantasy and Science Fiction (07/1964). Cantata-140 was expanded from the short story Stand-By (Amazing 10/1963). The Gollancz 2003 edition of Cantata-140 is the text of The Crack in Space, not the novella published in 1964.

Philip K. Dick
Philip Kindred Dick was an American novelist, short story writer, and essayist whose published work during his lifetime was almost entirely in the science fiction genre. Dick explored sociological, political and metaphysical themes in novels dominated by monopolistic corporations, authoritarian governments, and altered states. In his later works, Dick's thematic focus strongly reflected his personal interest in metaphysics and theology. He often drew upon his own life experiences and addressed the nature of drug abuse, paranoia and schizophrenia, and transcendental experiences in novels such as A Scanner Darkly and VALIS.
