When Doug Nash died last year, the incredible collection of Derbyshire caving and mining material accumulated over decades by himself and John Beck was bequeathed to the BCRA, who in turn passed it to the British Caving Library. Much of the mining material, including the Nellie Kirkham's collection was then passed to the Peak District Mines Historical Society, and the rest is now in our Glutton Bridge premises awaiting detailed cataloguing. More detail is available here:
