Portland
Steve Taylor/The Climbers' Club (2008)
The 2008 definitive guide, documenting most of the routes (including the few remaining trad routes) and a lot of the bouldering on the island. A spate of new bolting following (due to?) its publication means that quite a lot of routes, particularly in the lower (sub-5.10) grades were missed out. The guide also contains extensive information about the climbing around Lulworth.
The book is very clear, following the modern style of full-colour photo topos alongside the route descriptions. It is printed in a strange A5 landscape format, but this doesn't affect usability in any way.
