http://www.adobe.com/ As for Haynes, it's more of a numpties book that gives step-by-step instructions on how to pull things apart, then tells you that "reassembly is the reverse of dissassembly" which is why they are known as the Book Of Lies.
The workshop manual is far more in depth giving tolerances and settings in minute detail, but once you open the book you'll see what I mean.
There shouldn't be too much difference between yours and the manual, it certainly will be the same for all the basic stuff that you're likely to do yourself anyway.
But for 20 notes a Haynes manual isn't too bad.
