Elaine Scott has written numerous award-winning nonfiction books for children, including several on planets and space. About her research process for When Is a Planet Not a Planet? The Story of Pluto, she says: “This book was written as experts struggled with the definition of a planet, and therefore, Pluto’s fate. With no books on Pluto’s new status to consult, I relied upon daily news briefings from NASA and the International Astronomical Union. I consulted their websites, along with the sites of Caltech and Dr. Mike Brown. And I talked with many people. It was an exhausting but worthwhile process!” Elaine Scott lives in Houston, Texas.
