Journal
One of the best places to find out if a journal is peer-reviewed is to go to the journal website. Most publishers have a website for a journal that tells you about the journal, how authors can submit an article, and what the process is for getting published.
If you find the journal website, look for the link that says information for authors, instructions for authors, submitting an article or something similar.
