In reply to The Pylon King:
We have had this crop up on a few occasions over recent years from both sides - climbers not wanting their sensitive crag publicised, and land owners not wanting access to their land publicised.
In the latter case our line has always been that it is better to have clear and updateable access information, that can state that there is no right of access, than no information at all. This has always been accepted by the land owners seeking to protect access to their land.
The problem with a printed guidebook is that once it is out there, it can't be changed. The presence of a web site like UKC which can be updated I would see as a plus point in any access negotiations, especially where the guidebook was wrong.
There is of course also the BMC Regional Access Database which lists most of the crags as well so any discussion about the UKC Logbooks will also apply to the RAD.
There is also the reality that publicised access, and actual access are not always the same thing.
