Q. How do I determine if an article from this journal is peer reviewed?

Try:

• Consulting Ulrichsweb Global Serials Directory to find out if the journal is refereed. Refereed is just another term for peer reviewed.
• If you can't access Ulrichs, visit the publisher's website for the journal to determine what the review process is for that specific journal [i.e. How an article is accepted for publication?].
• Talk with your professor or a Reference Librarian to find out if the quality of the source meets the requirements of your assignment.
