The UKC Logbook database has over 150,000 routes on over 14,000 crags across the World and it is growing all the time. The system is hosted by UKClimbing.com but the information is supplied mostly from users who contribute missing routes and moderate crags.
All UKClimbing Registered Users can have a Logbook and you don't need to do anything special to set it up, just click on the Logbook tab in the menu bar and get started.
