Del Rey wrote the original (and much longer) version of this novella many years earlier, was unable to place it and only hauled it from the trunk when Horace Gold in mid-1950 solicited something for his new magazine. THE WIND BETWEEN THE WORLDS is at least in conception a standard ASTOUNDING problem-solving story (interstellar matter transmitter is sabotaged; Earth and alien ports are in danger, resourceful engineer-protagonist figures out the solution) with a standard STARTLING STORIES subplot (engineer and his pretty female assistant are deeply attracted but he's too dedicated to his job to get fresh). The premise however is ingenious—alien cultures intervene and as a result of this Earth is given the means for interstellar trade before the planet has even achieved space travel. Teleportation as an instrument of routine commerce (and profit) was a fairly original concept at the time this story was published. Del Rey's altered culture is lived-in, letting the story act as a letter from the future. Gold wanted the story significantly cut and del Rey of course complied; in THE EARLY DEL REY he used the original version and appended some notes on the nature of Horace's intervention.
