Information that is believable and convincing. Tends to be fact-based, produced by a reputable source, possibly written by an easily identified expert(s) in the field, current or timely for your topic.
Peer-reviewed
Prior to publication in a journal (typically), articles are reviewed by experts (i.e. peers of the author) within the research field. This extended process assesses the quality, significance, and validity of the manuscript before publication is approved. It is more intensive than proofreading or fact-checking.
Scholarly
Information produced by an expert for other experts to report on research or literature reviews on a topic. Scholarly articles published in journals, while high in quality, may or may not be peer-reviewed.
