Here's three utter, utter classics which just have to be posessed:
1. The Seven Mountain Travel Books, in a single volume by H W Tilman
2. The Six Mountain Travel Books, in a single volume by Eric Shipton
And, something completely different:
3. Cold Climbs: The Great Snow & Ice Climbs Of The British Isles, compiled by Ken Wilson et al.
This is not a climbing guide book, its coffee table size and entirely with b&w photographs and "stories" written by some very famous climbers for each route. A classic chapter is The Tower Ridge Rulebook (Ben Nevis)Check it out
