For this assignment, it is easier to start by finding the secondary article. You can either search for your topic in the "Search within this journal" box, or browse magazine issues by clicking a database link.
While you are scanning possible secondary articles, look for articles that mention a researcher, as well as possible keywords that will help you find the primary article.
Once you have clicked one of the magazine links above, click the "Search Inside" link. You will then be able to search for your topic within this magazine.
