In reply to Donotello:
Wye Valley Sport is the closest thing to gospel for sport climbs at WQ - there's just a couple of more recent additions. It only has a small selection of the trad routes though. The UKC database has all the trad. Those two sources are the only ones worth using for WQ - everything else is hopelessly out-of-date.
I moderate WQ for UKC, and it's my local crag: I try to keep it up-to-date. All the routes are there, both sport and trad, including the most recent, and they're in the correct order. More than can be said for many UKC crag pages! I haven't given photos more than a cursory glance, though - if you could let me know which you think are wrong I'll try to do something about it.
Not sure what you mean about Housequake/Croeso .... there are no routes between those two. Housequake enters the groove in the arete from the left, goes up it, and exits slightly right to the common lower-off. Croeso ... (too recent for the WV Sport book) takes the arete on its right-hand side. It's slightly eliminate because it uses a foothold in the groove to get started, and (possibly) borrows some crimps from the pre-existing trad route The 51st State just to the right. It's a bit squeezed in but definitely exists as a route in its own right .......
...... Unlike What Name! I'm willing to be told different, though, if anyone who's climbed it wants to make the case for its inclusion - but I can't see it myself.
