A day at Keyworth revealed that, contrary to its computerised index and the protestations of the librarian, the British Geological Survey does indeed have an almost complete set of 'List of Mines' and probably quarries from 1854 to 1950. Part of the problem was (and it might well apply at other libraries) that they had bound the list together with that year's statistics and (in older editions at least) the list of abandonment plans - it thus appeared in the BGS catalogue as "Memoirs of the Geological Survey Mineral Statistics of the United Kingdom of Great Britain and Ireland". In the older editions, the 'List of Mines' title is not used and the lists of coal pits appear as "Collieries in the United Kingdom". I've still not got the full story on Buile Hill stuff. The Lancashire Record Office now suggests that it only got the true archive material and the published stuff, including the List of Mines, should still be with the Manchester Museum of Science and Industry. They have promised to get back to me. Mike Gill
