-Professionals read and keep current in their fields by reading journal articles and relating them to their practice.
-Most article/literature reviews use a basic introduction-body-conclusion structure; if your lit review is part of a larger paper, the introduction, and conclusion pieces maybe just a few sentences while you focus most of your attention on the body.
-If your article/literature review is a standalone piece, the introduction and conclusion take up more space and give you a place to discuss your goals, research methods, and conclusions separately from where you discuss the literature itself.
