There are varying degrees of expertise:
Popular – Popular newspaper and magazine articles (such as The Washington Post, the New Yorker, and Rolling Stone) are meant for a large general audience, are generally affordable, and are easy to purchase or available for free. They are written by staff writers or reporters for the general public.
Additionally, they are:
- About news, opinions, background information, and entertainment.
- More attractive than scholarly journals, with catchy titles, attractive artwork, and many advertisements.
- References may be hyperlinks rather than formal APA citations.
- Sources cited may be people instead of journal articles.
- Published by commercial publishers.
- Published after approval from an editor.
