What makes information "scholarly"

Instructors often ask students to find “scholarly”, “academic”, or “peer reviewed” sources of information for their research.  These terms all refer to the same type of information – sources based on in-depth research, and are considered higher in quality and more reliable for your research. 

These sources can range from chapters within books or entire books, or journal articles, but all have common characteristics that can help you recognize that type of information.
