The Wonderland Supplement included most routes, though Baxter's guide had one addition route and some aid eliminations. I have checked the VCC site and Rock magazines (since the Rock Guide was published) and there appears to have been no further routes published since Baxter's guide in 1999.
The document is my working notes so does not come with a guarantee of reliability! The document is public and anyone with the link can view. In my view, the route descriptions are also public and people are free to use them, though I would appreciate knowing where so they can be kept up to date. The aim is to move the routes onto a public route register, such as 'The Crag'.
The other thing that I would encourage is that any new routes and updates are published (or publicised) through the VCC. This makes pulling routes together and updating public route registers so much easier.
Joe, you are welcome to have edit rights to the document. (The diagram and photo on the ACA site are nice and it would be a shame for them to disappear with the site!) Leave a message here and PM me your details. You are also welcome to add the routes to 'The Crag' (or wherever) and work from there. What have you got in store for us at The Workshop? ;)
