Explanation:
If the topic of what you will be writing is covered by the site produced by a reputable university, then you may use it as long as you include it in your paper for copyright purposes, like in your bibliography or footnotes in any case. Since the site is made from a "reputable" university and I emphasis the word in quoted marks, that it is legit and proven to be valid because a famous university will not try anything to squander their reputation, hence the issue of whether it is true or not has less doubt than any other site with no credentials.
So, yes. You may use that option as long as the content is what you've been looking for.
There are no restrictions on using works that are in the public domain, which means you can use them however you want—short of claiming that you created them yourself.
Hope this helps
