Q. Which journals have peer-reviewed articles?
A. To find out if a journal is peer reviewed (also known as refereed), you can use the Ulrich's International Periodicals Directory. Search by journal title, ISSN, etc. and look for the tiny referee shirt as an indicator.
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, 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.
Example: Manuscript received November 9, 2007; revised March 5, 2008. Published September 4, 2008.
