Distinguish types of articles found in scholarly journals. Your professor might ask you to find a specific type of scholarly article and now you can be confident in your selection.
Scholarly journals will publish some types of articles that are not peer reviewed or based on research.
Remember that not every article in peer-reviewed journals is a peer-reviewed research article.
Editorials: Often times the editor of a journal will write an article with his or opinion or summary of the article. This can lead you to good sources but are not appropriate for most research papers.
