Here is a short story about why this specific guide is so legendary in the climbing community: The Heavy Weight of a Small Book
Elias stood at the base of a sprawling, hundred-year-old White Oak, his neck craned back so far his helmet nearly fell off. He was a "green" apprentice, and the canopy above looked like a chaotic web of impossible angles.

As he swung into the inner canopy, the world below shrinking, he felt the ghost of the manual’s advice guiding his hands. He wasn't just a guy with a rope anymore; he was a student of the craft.
By the time he touched ground, the little book was tucked into his own gear bag. It was battered, and the edges were curling, but Elias knew he’d never climb without that "companion" again.
