In reply to SteveHolmes:
AFAIK the one I linked is the only 'overview' guidebook to bouldering in Spain, although I'd be delighted to be told otherwise. It was made by some visiting Germans, who toured Spain for a year hunting out the best spots in their opinion. I have visited the majority of the spots that the book lists in Catalonia, and they are all worth a visit; though it's true that the book leaves out several other areas near me which are also worth visiting.
Spain is still quite 'old-school' in its attitude to guides/topos, with much information found in local bars or now, increasing, online. So you will certainly find stuff if you hunt. And there are several comprehensive books for Albarracín, Savassona, Targassone (technically in France, but only just!) and elsewhere.
Re: Portugal: despite having been there dozens of times I'm afraid I know very little about the bouldering, other than to say the climbing there is limited compared to the endless volumes of rock in its Iberian neighbour.
