We've got the original 2009 books, to be honest haven't used them in anger for years.... but a good insight to potential areas.
Instead look up Bergsteigen.com, select 'Tours' and then 'Klettersteig', use the map view option and zoom into the area in the Dolomites you want to go. There you will find virtually all the Via Ferratas in the Cicerone guide plus some more, an up-to-date description and route timings, all the information you need on parking, approaches, descents, huts etc. It's in German, but Google translate is pretty reasonable. Best of all there are usually plenty of photos and a detailed topo you can download and print off. It grades each part of the route, so you can see how easy or hard each bit is. It uses just a single letter, A (Easy) to F (hard!) as grades, think French sports grade to British 'trad' grade on a climb as a comparison.
Been using this site for years - they have loads of Alpine and winter climbs, mountain and ski ascents as well, find everything pretty accurate and up to date.
