The other user helping with this article is an academic expert. So I wanted to make the references simple as could be and just did them like this <ref>Rotter (1954)</ref> or like this <ref>Millon (2004), p. 353</ref> The list of books and websites is at the bottom of the page. With websites as links, this does not work an obviously simple way, though.
With that you have to follow the footnote, read the short form of the reference and then manually find the long form. With only a few references, it's not too bad, but that system certainly doesn't scale to pages with dozens of references.
