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.
- Download PDF: this directly downloads the article PDF for you.
- Article Link: this will lead you to the direct link of the article, where you would be able to download the PDF.
- Access Options: this leads you back to SUSS Library's search for a list of available options. If you are unable to access the article via SUSS Library's search, you can click on the DOI number/link, which will lead you directly to the article link. From there, you would be able to click on the blue button on the bottom left corner, and get access to the article.
