I stumbled over europeanpages.org about a week ago and I have to admit the site is extremely useful! I wish google and the others would follow suit. Europeanpages have broken down their site into 5 different sectors that can be selected from the front page. If you can't find what you need then they have more search options. I have used this site many times over the past week and have found it very user friendly, I just wish more people knew about this site, it looks like a lot of work has gone into it with very little recognition.
I managed to find the admin email address and they have a sneaky trick up their sleeve so people searching through their site can actually earn money while doing so :)
