Yes there are two sources I know of: RootsWeb WorldConnect database "bschultz" and World Family Tree vol 22 tree 0573. You can download a GEDCOM from the RootsWeb database. There are a lot of quotes from the book, shown as notes in the genealogy. There is also an email address for B Schultz shown at RootsWeb. But I don't know how to get a copy of the book.
