Your professor has a list of preferred journals for you to find articles in. See below.
Not sure how to search a specific journal? Check out our Access Individual Journals & Specific Articles, linked in the list under the Research Tutorials tab here.
If you're searching a database and want to see if an article you found is from one of these preferred journals, look at the info page for the article. It will be there somewhere under a label like "Journal" or "Source."
