In reply to ford23:
I've used "Passages Pyrénéens" which is pretty good for the areas it covers (central Pyrenees, French side) but I think its out of print & someone has my copy. The only climbing guide I've seen in English is old, only covered a few areas and best avoided.

"Pyrenées, les 100 plus belles courses et randonnées" by Patrice de Bellefon might be of interest,

The same website has sections on climbing & walking guides (not just the Pyrenees) which may be of interest (e.g. Sommets des pyrénées, Les plus belles courses de F à D; Petit crapahut, Dans les Hautes-Pyrénées, en pays Toy, Gavarnie, Troumouse, Barège, Tourmalet, Mongie; Pyrénées, randonnées insolites; Escalades à Ordesa, Escaladas en Ordesa )
