Use the RADAR framework when using a new source to determine its legitimacy.
Relevance: How is this information relevant to your assignment?
Authority: Who is the author? This can be either a person or an organization.
Date: When was the information published?
Appearance: Appearance is not always the best clue (see All About Explorers for an example of a fake site that looks legitimate), but is the information presented in a serious, professional manner?
Reason for Writing: Why was this information published?
This framework is not the only way to tell if a source is legitimate, but it is a useful starting point for students.
