I have just returned from my 2nd trip to the Dolomites. I used this book on both occasions and found it to be very helpful. We found the descriptions for the routes we did to be very accurate. The timings for us were a little ambitious, though, we found we could only just keep to them on some of the routes, by keeping breaks very short. I like the way they grade the routes, and group them by where you start, rather than mountain group. Although there is an index in the back by mountain group, and grade, so you can refer to those if you're looking for something specific. Otherwise, I think it's useful to go to the section of where youre staying and find all the closest routes together. I thought it would have been helpful if the maps in the book had labelled the trails by number, but then I realised they may have avoided this so that people were not tempted to rely on the book alone and not carry a map, which would not be a good idea.
The book has a very useful section on kit etc at the beginning, and provides enough info for a novice to start climbing from scratch, I would say, as long as you start with easy routes. But if in doubt, get someone to show you the ropes!
