Types of Periodicals
Scholarly Journals, magazines, newspapers, and trade publications: what's the difference?
Check out this video on "Magazines and Scholarly Journals" from the University of Arkansas Libraries.
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.

Classification of Resources
Primary, Secondary, and Tertiary: what's the difference?
Check out this video on "Primary, Secondary, Tertiary Resources" from the Beam Library at Oklahoma Christian University.
PRIMARY: materials represent an original work (text, painting, or item) and/or document an event at its occurence (photograph, diary entry, or letter).
SECONDARY: sources are analyses of, commentary on, critiques about, or responses to Primary Sources. Reputable secondary materials have been well-vetted via the peer-reviewed process. Subject specific encyclopedias are often considered seondary sources and great for consulting during initial research, however you generally do not want to use such sources for direct citation.
TERTIARY: items are often compilations of excerpts from Secondary Sources and can be used to identify themes or threads pertaning to concepts in a discipline.
