The work of William Collinge is amongst the best I've found too. It truly helped me to recover as much as possible; it guided me in many ways and gave me hope and guidance that I did not get anywhere else.
The book is titled "Recovering from Chronic Fatigue Syndrome: A Guide to Self-Empowerment"
There are also audio CD's to accompany the book. The book can be downloaded FREE from the following site: http://www.collinge.org/Cfs.htm
