Some of the library's online databases offer the option to limit search results to articles from peer-reviewed journals. This should weed out articles from magazines, newspapers, and non-peer-reviewed journals.
NOTE: Not everything published in a peer reviewed journal is a peer reviewed article. Peer reviewed journals typically include letters to the editor, commentaries or book reviews. These are not considered peer reviewed articles. Look carefully at the articles in your list of results to make sure they have the criteria for a scholarly article.
There are two major types of periodicals: Scholarly/Academic or Popular.
Some scholarly journals are peer reviewed. Most databases offer this as a filter. Use the limiter if "peer review" is a criteria an instructor requires for your assignment.
The physical appearance of print sources can help you identify the type of source as well. Popular magazines and trade publications are usually glossy with many photos. Scholarly journals are usually smaller and thicker with plain covers and images, In electronic sources you can check for bibliographies and author credentials or affiliations as potential indicators of scholarly sources.
