We walked the Ridgeway in May 08 and found this book invaluable especially as between the 3 of us we had no sense of direction or distance travelled. This book gave us enough information step by step. There were one or two inaccuracy's that we noticed, but mainly landmarks like the Double Decker bus near Sparsholt Down, which was no longer there because the owner had moved on. If you were limited with space in your backpack and required a comprehensive reference to the Ridgeway, I would certainly make room for this travelling companion. This publication was definitely our 4th member of the team!
