Libkey Nomad is a browser extension that allows you quick access to journals and articles, even when you are browsing online and outside of SUSS Library's search.
When you are on the article page, a blue button on the bottom left corner will show up.
Click on the button, and you will be granted access to the article.
We must preface this to say Wikipedia is not a reliable source (here's why), and you cannot cite from Wikipedia. However, you may refer to the list of references used, and evaluate for yourself whether these articles are credible, useful, relevant to you.
In the citation section of Wikipedia, you would see various access options (in the blue buttons) in the list of references.
