To find peer-reviewed journals, search a library database such as SLUth Search Plus and limit your search results to peer-reviewed journals. Many databases (SLUth Search Plus, all EBSCO databases) offer this option.
You also always have the option to go to any particular journal's website to find out if it is peer-reviewed. Look for a section that includes author submission information. This should include information about the journal's review process.
