Herbert's interest in the desert setting of "Dune" and its challenges is attributed to research he began in 1957 for a never-completed article about a United States Department of Agriculture experiment using poverty grasses to stabilize damaging sand dunes, which could "swallow whole cities, lakes, rivers, and highways." Herbert spent the next five years researching, writing, and revising what would eventually become the novel "Dune", which was initially serialized in "Analog" magazine as two shorter works, "Dune World" (1963) and "The Prophet of Dune" (1965). The serialized version was expanded and reworked—and rejected by more than 20 publishers—before being published by Chilton Books, a printing house best known for its auto repair manuals, in 1965. "Dune" won the inaugural Nebula Award for Best Novel in 1965, and the 1966 Hugo Award. The novel has been translated into dozens of languages, and has sold almost 20 million copies. "Dune" has been regularly cited as one of the world's best-selling science fiction novels.
