Books that I have are on Slovenian that is why I didn't mention them. Most important of them is certainly Julijske Alpe (Julian Alps, obviously :-) guide by Tine Mihelic. As you asked I've checked on UK Amazon and found there are books on English, like: Walks in the Julian Alps by Simon Brown. How good is it I don't know. There are also books and maps on German Amazon (if you speak German :-).
Bitte Diego :-) Anyway, till you decide to visit Julian Alps I think every peak will be covered on SummitPost and no book guide is good like this site is. It is just nice to have a book in hands. Imagine SummitPost encyclopedia printed, that would look awesome!
Now this is nicer page Sasha because there are described all three Mojstrovka. I will try to describe today the section about Nad Sitom glavo today and I will send you. I see that I can add also the photos of Mala, Velika and Zadnja Mojstrovka. I will add it.
