Considering WinRunner is now at version 9.2, and that book you list is crap to begin with, you should stop trying to locate it.
Why specifically WinRunner? Why not focus on the skills needed in general to move to Automation. How many years of Manual testing have you done? Enough to be proficient in the general policies and procedures? Have you put a good amount of practice into testing and what to go to the next level or are you jumping into something becuase it pays more?
Automation is something to be built on manual testing experience and a good foundation of knowledge of QA policies and procedures. Programming ability is also required to become successful and not just a record and play back scripter that is for the most part useless.
THe book you reference as LynneM points out is only delivered with the Application. There is another book that was published out of India that for the most part couldn't reference the application directly due to copyright, and was very light on anything truly WinRunner specific.
