The companion book for the series, The Power of Myth, (Joseph Campbell, Bill Moyers, and editor Betty Sue Flowers) was released in 1988 at the same time the series aired on PBS. In the editor's note to The Power of Myth, Flowers credits Jacqueline Kennedy Onassis, as "the Doubleday editor, whose interest in the ideas of Joseph Campbell was the prime mover in the publication of this book." The book follows the format of the documentary and provides additional discussions not included in the original six hour release.
