kindle The historical information within this site, while constantly updated, is drawn largely from the book, FOR THE GOOD OF MANKIND: A History of the People of Bikini and their Islands, Second Edition, published in September of 2001 by Jack Niedenthal. This book tells the story of the people of Bikini from their point of view via interviews, and the author's more than two decades of firsthand experiences with elder Bikinians.
