Once you locate a few good articles on your topic, be sure to review the references to other articles that are cited. Also look for the "cited by" link in some databases. This is a great way to locate related research articles on your topic. Many databases also provide a link to these articles if they are available. If a link is not available, use the Journal search from the library homepage to check if we have access to the publication. If we do not have it, you can request the the article using our awesome Interlibrary Loan Service.
It is usually a good idea to start out broadly, so using just one or two of your topic terms is a good way to begin. Once you have a set of results, you can begin narrowing down your results by entering one or more terms. Searching in a specific field such as "Subject" or "Title" will narrow or focus your results.
