Types of Articles
Articles used for research could come from popular magazines, such as Time or Sports Illustrated, trade journals, such as Advertising Age, or scholarly journals, such as The Journal of Business Ethics.
Popular magazines, like newspapers, are written for around an eighth-grade reading level in order to reach a broad audience. They are often printed on glossy paper, contain advertisements, and could be described as "flashy."
Trade journals combine aspects of popular magazines and scholarly journals. They are written specifically for people working in a particular field or trade, contain advertisements for products important to the trade, and may be printed on glossy paper and have a "flashy" feel.
Scholarly journals are written for a specialized, professional audience using formal, scientific, or complex language. They contain few advertisements but may contain charts and graphs. Articles are quite lengthy and generally include footnotes or a bibliography. They are often published quarterly or biannually, and page numbers may run continuously through an entire volume rather than start over with each issue.
Many scholarly journals are peer-reviewed, which means the articles have been vetted by professional peers to ensure that they are sufficiently scholarly and original prior to publication. All peer-reviewed journals are scholarly, but not all scholarly journals are peer-reviewed.
