Because this book was published in 1987, it is not easy to get an eBook. A suggestion is to read the latest papers or the author's articles. I have searched the author in the Jstor database, but can't his paper.
According to http://en.wikipedia.org/wiki/Larry_R._Williams, most of his achievements iare books. Maybe you ask for those who are studying in USA for help, or write a letter to the author (WILLIAMS9252@YAHOO.COM).
