I think a lot of copyright issues differ a lot from one country to the other. Therefore, the best advice I can give you is to consult a lawyer specialised on online issues and/or intellectual property.
One example: A full page of my website was translated 1:1 for a daily paper in Austria without permission or even consultation. When I asked a lawywer about this, he said that because the paper gave the URL, there was nothing we could do. So unhappily, I didn't follow up on it. I guess I could have taken legal action in many other countries (at least respectable ones).
