Q. How do I know if an article is peer-reviewed?
A. Not every article in a peer-reviewed journal is a peer-reviewed article. Some scholarly journals also publish letters, book reviews, conference notes, news items, etc. Look at the full text of the article you're interested in. A peer-reviewed article will show a string of dates, usually either near the abstract or at the bottom of the 1st page of the PDF version or at the end of the article, to indicate that the article was reviewed and usually revised.
