It is now 50 years since industrial archeologists published one of the most important on mining in the Pennines. The book of the above name- no not the 50!, was the work of A. Raistrick and B. Jennings.
At the time it was a dramatic book, since it it showed two maps, of interest to all mine explorers, a diagram of the integrated Nenthead mines set up and also a similar one of the Arkengarthdale/Swaledale mines. It also gave us some ideas about the social background of the miners. It is still worth a read.
On reading it again one question arose in mind what happened to Raistrick's own documents? Many of these relate to the early years of the L.L.C. and so the whereabouts of them would be of interest to many on this site.
