The Crack In Space

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.
