Alpine Ski Montaineering contains excellent information, maps, and photos in a sensible format - flexible plastic covers, which goes into your rucksack. Of course, you do need local maps for detailed navigation, but this book pulls together the plan for the day and provides an overview. The route descriptions are not overlong, but this helps keep the size of the book down. I have skied some of this terrain, and look forward to more.
I really look forward the the volume which covers the far East, from Innsbruck on past Grossglockner.
