For other researchers who merely want to do research on William Story and his descendants and are not as particular about having the physical book, a related book by a different author has been digitized and is available for short-term loan at the Internet Archive. That book is Descendants of William Story and Sarah Foster of Ipswich, Essex County, Massachusetts, compiled by Betty Andrews Storey.
On the title page, Ms. Storey comments:
The Descendants of William Story and Sarah Foster of Ipswich, Essex County, Massachusetts is a result of the help of many individuals that I have corresponded with over the years. . . . I have included charts to show my two lines of descent from William Story and Sarah Foster.
I refer to "The Descendants of William Story Who Came to Ipswich, Massachusetts in 1637" by Robert L. Pratt. Published in 2000 by Gateway Press, 1001 N. Calvert Street, Baltimore, MD 21202 in my compilation.
The first half of Ms. Storey's book contains nearly 150 footnotes citing Pratt's book. Ms. Storey's book begins with pedigree charts for her family's ancestry back to William Story and Sarah Foster, but the bulk of the book is a NGSQ System report of William Story and his descendants.
Ms. Storey provides her contact information (as of April 2004) on the title page.
