I think the issue of it being a charity is irrelevant and shouldn't be an issue at all. I don't want to see charities "allowed" to link to others and everyone else not allowed.<p>This is just links. How does the World Wide Web work without linking? It doesn't.<p>What is the current legal status of linking?

At least there, there is a question to evaluate if it is fair use or not.<p>If referencing articles through hyperlinks is determined to be a copyright violation, then it is also a copyright violation to cite sources in the footnotes of an academic paper.
