How to tell if journal is "peer-reviewed" or "refereed"
Most databases allow the user to limit by peer-reviewed journals or some databases index only peer-reviewed materials.
Search at the journal's homepage page by looking at the editorial statement or instructions to authors to determine if the journal is peer-reviewed. Be careful as some journals claim to be peer-reviewed but do not have a true peer review process.
