Most popular journals, such as Time and Esquire are not academically or research- focused. On the other hand, American Literature, ELH , or The Journal of Modern Literature are examples of scholarly, peer-reviewed journals that are generally preferred by researchers.
Features of a Peer-Reviewed Journal
Articles submitted to peer-reviewed journals for publication consideration are sent by the editor to several reviewers who are experts in the field covered by the article. These experts then contact the editor with a recommendation to publish or not to publish. This rigorous review process gives articles credibility and intellectual prestige.
Most popular magazine articles written contemporaneously to the time studied are considered primary sources.
