Hefner's role in editing this book, specifically, is slightly in question. He was EIC of Playboy at the time, and was the active editor of the issues from which this book mined its contents. What's a little less clear is whether there was some "intermediate" editor of just this volume. In any case, without him editing Playboy as he did, there wouldn't have been this volume. He certainly deserves credit for editing the individual stories in this volume.
