Peer-review is the key distinction between scholarly and non-scholarly sources.
In contrast to popular newspapers, magazines, websites, and books, scholarly sources are written by experts in a particular field and then reviewed (evaluated) by other experts in that field prior to publication.
Why? It is important to critically evaluate information that you are using, either in a paper, webpage, or for decisions in your personal life. This is not always easy.
