Soon, Herbert’s research into dunes became research into deserts and desert cultures. It overpowered his article about the heroism of the men of the USDA (proposed title “They Stopped the Moving Sands”) and became two short SF novels, serialised in Analog Science Fact & Fiction, one of the more prestigious genre magazines. Unsatisfied, Herbert industriously reworked his two stories into a single, giant epic. The prevailing publishing wisdom of the time had it that SF readers liked their stories short. Dune (400 pages in its first hardcover edition, almost 900 in the paperback on my desk) was rejected by more than 20 houses before being accepted by Chilton, a Philadelphia operation known for trade and hobby magazines such as Motor Age, Jewelers’ Circular and the no-doubt-diverting Dry Goods Economist.
An interesting 50-year retrospective of Dune.
