Links and Law und Links and Law: Myths
The ability to refer to a document (or a person or any thing else) is in general a fundamental right of free speech to the same extent that speech is free. Making the reference with a hypertext link is more efficient but changes nothing else.
When the "speech" itself is illegal, whether or not it contains hypertext links, then its illegality should not be affected by the fact that it is in electronic form.
Users and information providers and lawyers have to share this convention. If they do not, people will be frightened to make links for fear of legal implications.
Tim Berners-Lee, April 1997
