Very hard to find now, but there is a great handbook, gathering all 4000m alpine peaks, called :
"4000 des Alpes" by Richard Goedeke - Oct. 2003
(ISBN : 2907781634)
Yes, I own this book in the German version.
Thanks for the idea to add a book section.
I made a book list about South-America. It would be good to have the same for the Alps one day.
you can change the link of Breithorn / Roccia Nera to my page if you want:
it's not an important peak but it's interesting
