The first thing you should do when you have a research assignment is figure out what types of article sources are required or allowed. Some professors require you to use only scholarly peer-reviewed journals while others might let you use professional journals (also known as trade journals.
Scholarly article - written by an expert in the field and reviewed by peers who are experts in the same area. In many databases, you can limit your search to scholarly, peer-reviewed or refereed journals to weed out any non-scholarly content.
Popular journals - Written for a general audience rather than for professionals or scholars. Examples include The New Yorker, People, and Rolling Stone.
