A very good guide. Contains a multitude of climbs on every crag covered (most classics and star climbs, poss. all), over 900 climbs on Stanage alone. If you bought the definitive guides for each crag covered you would not get a great deal more for your money. There are enough climbs to keep an average climber going for 20 years or more. The photographic topo's and crag maps are very good. Crags covered :- Wharncliffe, Rivelin, Dovestone Tor, Bamford, Stanage, Burbage North and South, Higgar Tor, Millstone, Lawrencefield, Yarncliffe, Froggatt, Curbar, Baslow, Gardoms, Birchen, Chatsworth, Cratcliffe and Black Rocks (over 2900 routes in total).
