Dream Makers

Publisher's description (via Google Cache): "When Charles Platt set out to answer the question, "Who writes science fiction?" he interviewed almost all the writers who molded the field during the 1960s, 1970s, and 1980s. The profiles that Platt wrote have become a definitive source of information about the lives and careers of Isaac Asimov, Jerry Pournelle, Frank Herbert, Frederik Pohl, and dozens more. Originally published in two volumes, the profiles collected here have been specially updated with afterwords written in 2017."
