The only problem with Mike's suggested alternative name is that COPD attempts to describe the caves exhaustively together with any mines of special interest to cavers. If it were to be called "Caves & Mines of the Peak District" it would then have to try to describe all the mines exhaustively as well - this would be a very different animal!
It wouldn't be a guide book of several volumes - more a Library!
I don't think anyone knows precisely how many mines (lead or otherwise) there are in the Peak District, much less enough detail to include much about all of them in a large set of guide books.
At a talk given in our village hall (Winster) last year or the year before by a mine historian there was a map showing locations of mineshafts in Derbyshire.
These were represented by three different kinds of circles. There were many of the first type representing shafts whose location is known and are capped because they are near Public Footpaths, etc.
There were a
lot more representing shafts whose location was known but were largely not capped as they were not near any Public Footpaths.
Third, were the circles representing shafts which were known of from mine records but whose location was not precisely known. These were so numerous it looked like the map had spent years hanging up In a pub behind the dartboard! Of course there will also be a lot more whose details are lost.
Of course many caves in the Peak are also part mine and many mines are part cave and these are included in "Caves of the Peak District". If COPD were to include only natural caves, it would be a very slim volume indeed.
