I'll give you a somewhat more concrete example. For example, in the United States, you may have heard of the Google project to digitize all literary works in the world. They have somewhat limited the agreement they signed, but they want to digitize all literary works. They take the works, they copy them, they digitize them and subsequently make them searchable so that people can find them on the Internet. Google claims that this use—which is an enormous use, as you'll agree with me—is fair in the American fair use sense.
So that will be very far from what people think or could try to put into this fair dealing context.
