POPULAR SOURCES: Popular sources contain articles on topics of popular interest written in a non-scholarly style, while journals contain articles of original research and commentary including footnotes and works cited. Avoid citing popular magazine articles in your work. If a magazine article contains compelling information, look for references in the article and then locate that reference source for use in your assignment.
TRADE PUBLICATIONS: Trade journals are aimed at readers who operate within a specific industry. Some journals are accessable online for free, and others require a subscription. The EKS Library provides access to databases that contain articles from an array of trade publicaitons.
SCHOLARLY JOURNALS: are peer-reviewed or refereed journals. Prior to publication, articles undergo a critical review process by experts / referees on the subject who evaluate the quality of the research.
