The fourth book in the series is devoted to the registers kept by mountain huts and hotels, and to the Fuhrerbuchs, or 'testimonials', kept by mountain guides, diaries written in a spontaneous and informal hand that conserve the tales of great mountaineers, simple hikers or day-trippers and that stand witness to a climb or holiday.
