Some UK press on the launch of Europeana:
BBC online: European online library launches
Guardian: Dante to dialects: EU's online renaissance
Associated Press: European history, culture and art goes digital (well not really UK but never mind)
I'll keep editing this stuff as I find more. Plenty of concentration on the awesome content as well as the fact the site was brought to its knees by huge traffic, which I'd see as a success of sorts - best see how the traffic holds up over the next few weeks, though.
