In reply to Tony the Blade:
> The best book by a country mile (imho) is The Mont Blanc Masiff by Gaston Rebuffat, it's one of my favorite books, ever!
Second vote for the Rebuffat book. It is a little dated now, and some of the route descriptions do need comparing with more recent guidebooks, but in terms of purely inspirational mountain porn, this book is the business.
The most up to date route information can be found in the Guide's Office in Chamonix, so you can always go there to browse and then photocopy etc.
The full Rebuffat route list is here
