In reply to DaveX:
of the more recent books that have come out I highly recommend 'In Some Lost Place' by Sandy Allan, for real commitment, so many hard days above 7000m on Nanga Parbat;
for classics, I second pretty much anything by Shipton and Tilman, those guys were 'hard' and the miles they got through in such tough conditions with only very basic kit, were incredible;
for a bit of a 'who done it' have a look at 'Dead Mountain: The Untold true story of the Dyatlov Pass Incident' by D Eichar, in 1959 nine hikers died in the Ural Mountains in mysterious circumstances;
for Munro planning I always used 'The High Mountains of Britain & Ireland' by I Butterfield, a far better book than the SMC Guide or any others;
for fiction, it has to be 'The Ascent of Rum Doodle' by W Bowman, I've just found a first edition with d/w for an incredibly cheap price, so feeling very pleased with myself!
