Fifty log books, 1961- 2008, recording Hamish Brown's climbing activities (including the many expeditions he led from Braehead School, Fife), but also his endeavours in many different fields, the logs are also travel journals notably of visits to Morocco, and diaries recording daily life. The meticulously kept notebooks have been bound together to make manuscript volumes. The notebooks include verse together with numerous pasted in photographs, sketches, press-cuttings, postcards, verse and letters. Correspondents include Janet Adam Smith, 1968, and the climber, Jim Gaitens, 1976.
