Any of the books by Ronald Turnbull are worth reading.

His "Long Days In Lakeland" is a classic, with photographs that rival Stolly's.

His three Guide Books for Walkers and Fellrunners should be on everybodies bookshelf:-

Lakeland Mountain Challenges
The Welsh Three Thousand Foot Challenges
Across Scotland On Foot
