Using the citation, there are a few ways to search for the articles the citations point towards.
First, probably the easiest, is to search using just the article titlein Primo Pathfinder. If the article title is somewhat vague, you can adding the first author's last name (etc) to narrow it down.
Second, slightly more complicated but more specific, is to find the journal title and to go to the Journals & Periodicals search. From those results, find a database that has the journal/article, and then click the link and follow the page to get to the article you need (either by date or by "search inside publication", etc).
Third, if we do not have an article and you have used both methods above (and only after you have used both methods above), you can try and place an interlibrary loan request using the information from the citation.
