Does the article provide a detailed list of references? Scholarly and peer-reviewed research articles always include a bibliography or reference list of works consulted by the author and have clear in-text citations or footnotes about the sources used in the article.
Sources must be clearly indicated. There should be no question about who is responsible for the information, and where the information is coming from.
Avoid articles that contain spelling or grammatical errors.
Be aware of any bias on the part of the author or publisher, especially from non-scholarly sources such as newspaper editorials and opinion pieces.
