Defining Article Types

Research Articles

"A research article reports the results of original research, assesses its contribution to the body of knowledge in a given area, and is published in a peer-reviewed scholarly journal." - Pen & the Pad

The study design of research articles may vary, but in all cases some form of raw data have been collected and analyzed by the author(s).

Review Articles

"A review article, also called a literature review, is a survey of previously published research on a topic. It should give an overview of current thinking on the theme and, unlike an original research article, won’t present new experimental results." - Taylor & Francis Author Services

Review articles provide a comprehensive foundation on a topic, and, as such, they are particularly useful for helping student researchers get an overview of the existing literature on a topic. 

Differences between Research and Review Articles

Conducts an experiment and reports what was found. Discusses what is already known and identifies gaps.
Contains NEW original research data. No original data are presented.
