In reply to Jon Greengrass and Graham D:
Local guidebooks are great if you can get hold of them, and they are properly produced. Sadly this is frequently not the case in France where little local guidebooks, covering single crags, with poor topos and general information, is often the reality. For travelling climbers it is often hard to plan a trip when you can't get the guidebook before visiting the local shop or bar. French web sites are still in the 90s which doesn't help.
A guidebook like the one suggested in the OP could be very useful. Lots of crags covered in summary details, with a topo or two at each crag but not comprehensive cover. Such a book would probably open up many more French crags to visitors, increase local guide sales and take the traffic away from the better known venues. Guidebooks like this have exisited in the past and done fine, and also Jingowobbly's Sport Vertical is half-way there since it at least lists all the crags, but doesn't have much actual topo information.
This idea that you should support the local guidebook since it funds the bolting is at best a distortion of the truth and at worst just an excuse for a poor guidebook. No guidebook could possibly fund local bolting in its entirety, most could only make a small contribution to the process. In terms of people who make money out of bolted climbs existing, guidebook producers are well down the list of those raking the money in - think local gear shops, local accommodation, gear manufacturers, climbing walls, etc.
Additionally, the whole guidebook-funded-bolting thing is said to happen in loads of places where it doesn't and there is also little guarantee about what it is used for. For example, would people who bought guidebooks be happy about a guidebook-bolt-sub going to bolting new routes in some steep cave?
