Professors will often ask you to find articles that are scholarly.  What does that mean? Journal articles are usually "scholarly" while magazine articles are "popular".  Trade publications are specific publications that are targeted to people who work in specific industries for example: the advertising business.  Most databases supply a tab or filter to allow you to select scholarly and "peer-reviewed" articles.
