One of the biggest benefits of using library resources is the ability to refine your search to narrow down your results. You can do this using limiters. In Scopus, these limiters appear on the left side of your search results.
For this project, you'll want to use the Year limiter to look at only the most recent results and the Document Type limiter to see only journal articles. You might also consider the Language limiter to see only English-language publications and the Subject Area limiter to focus down on the results you want.
