From Dr Nicholas Ardizzone I put your query to my wife who is a clever television researcher: I paraphrase her advice here, but first a little background might help. Assuming you are looking worldwide, the best UK source is in the records of the National Coal Board, which ran the nationalised coal industry here since just after WWII until it was de-nationised during the Thatcher convulsion recently. As will happen, the visual collections, film and stills, were hived off to whoever bid for them and, tragically have become fragmented but, mostly, still are traceable. The British Film Institute have fine stuff, but Antoinette suggests a good first port of call could be: Beamish Open Air Museum County Durham DH9 0RG Phone 44 1207 231811 x208 Fax 44 1207 290933 e-m [log in to unmask] Best Nick Please Antoinette's website http://members.aol.com/antgraves/homeag.htm
