In reply to TommyK:
Not sure why you think maintaining info on guidebook coverage and availability is the CC's responsibility any more than anyone else's?
UKC/Rockfax have any equally hit and miss approach in this area.
For future reference, the only organisation that has consistently made any successful attempts in this regard is Needlesport. They've maintained near comprehensive availability of all UK climbing guidebooks as a point of principle for decades.

"We stock every British Climbing Guide Book in print that we know of, and also list as well, a few just out of print ones. This is (as far as we are aware) the only site containing this information that is kept up to date. Please let us know of anything we have missed."
