Linking to other websites in articles

Hello, I am currently writing an article about the dangers of caffeine, and I thought it would be best to link to a scientific study within the article. I was wondering if this was allowed, or should the article be completely free of any links? Thank you.

If I'm adding links to resources used for research purposes, I'll make sure the link isn't active when I post it. Remove the http://www. part of the link so the rest of the URL is still visible if the client wants to use it.
