By "completion" I don't mean I did any writing or original research. The book was a work in progress, and Elliot left behind some notes and ideas for how he planned to complete it. His plan called for a book three times the size of what was in the manuscript. All I did was add a few easing transitional phrases between sections and write a brief foreword. The rest is pretty much as Elliot left it.
It's been published now because more than anything else, Elliot wanted to be sure it could get into the hands of others who needed the information it provided. That's also why the price has been set extremely low (99 cents) -- as low as Amazon would allow, actually.
I will be back again later in September. In the meantime, we hope that this final work by Elliot will be a blessing to all who read it.
