I have the 2005 version of that massive guide. It is a thick double book shaped folder, with maps, French and English overviews and French route details and several other pamphlets. It includes a plastic map case to wear around your neck.
We bought it after spending a night in Vezelay and our way by car to LePuy. The trail from Vezelay looked so great we almost started there, and have had the route on our list ever since.
When we do the trip, the only part that will come with us is perhaps the French part on history and buildings, and the lodging lists. We'll put the route and maps in the GPS.
