In reply to rnotman67:
The best one for you is called Escalade en Brianconnais, haut val durance & queyras by Yann, Martine et Jean-Jacques Rolland.
It covers most of the lower sport crags in the valley and has English translations. There's loads of variety from limestone to granite slabs to quartzite, but don't miss the amazing Mont Dauphin conglomerate.
I've not seen the guide available in this country, but is readily available in the valley.
