In reply to crimpsoplenty:
The publisher is Great Western Rock; there's a Facebook page at Wye Valley Sport Climbing.
Regarding the Wyndcliffe Quarry UKC page: there are no topos, but (although I say so myself) at least everything's there, in the right order, and almost all the routes have some sort of description; I would hope that not much deciphering is necessary - it could be a lot worse, anyway :0
