I was researching a lot about NASA's Mars helicopter - Ingenuity and found couple of research papers, so I though I'll publish the list on my blog. List would include title of papers with appropriate links to PDFs. The PDFs are hosted _somewhere_ and they are easily reachable if you just google the research title. I gave up eventually since I'm not sure if this is legal or not.
A known counter-example was someone condemned mostly because of admitting browsing up the directory and realizing that the files were supposed to be protected by a login + password :
although some countries have these linking rules I don't think they generally apply to research, that is to say if they research is available it is legal to link to. Research from American governmental agencies is also paid for by American tax money and thereby, under the American model, owned by the public and publicly linkable.
