It's often difficult to tell the difference between original research articles and review articles. Here are some explanations and tips that may help:
Primary research articles are written accounts of research conducted by the authors. The articles can be identified by a commonly used format. Primary research articles contain:
Abstract - summarizes the research findings and is a tool to help determine the type of article. If there is no abstract at all, that in itself may be a sign that it is not a primary source. If it is primary research, the article will discuss steps and tests done in their research or experiment, much like you write up a lab report.
Review articles summarize, analyze, and evaluate current research related to a specific topic, field, or problem. They are often lengthy with a large number of citations. Since they review previously published material, review article are considered secondary sources. They can be of great value for identifying potentially good primary sources, but they aren't primary themselves.
