Popular: Sources published in newspapers and magazines intended for general audience.
Scholarly: Well researched sources that have been written for scholars, students, and experts in the discipline area.
Peer Reviewed: Articles that have been evaluated by other professionals in the field to check for accuracy and adherence to disciplinary standards.
Know the Difference
Article: Articles are the individual "stories" published in a newspaper, magazine, or journal. For example, the story about the Rangers published in Sports Illustrated is an article.
Journal: Journals contain several articles published about a specific subject area and are typically scholarly. For example, the article about stem cells was published in the Journal of Medical Ethics.
Database: Databases index millions of articles published in thousands of newspapers, magazines, and journals. There are databases that index sources from many different discipline areas, while others are subject specific. For example, the New York Times can be accessed by searching the database Nexis Uni.
The CRAAMP test is a valuable tool for helping you determine if an article you are reading is credible and a good fit to use as a source for your research paper. As you read, pay attention to the 6 following criteria.
Use the template below to chart each of these criteria in the articles you use for your research paper.
Peer Review is a critical part of evaluating information. It is a process that journals use to ensure the articles they publish represent the best scholarship currently available, and articles from peer reviewed journals are often grounded in empirical research. When an article is submitted to a peer reviewed journal, the editors send it out to other scholars in the same field (the author's peers) to get their assessment of the quality of the scholarship, its relevance to the field, its appropriateness for the journal, etc. Sometimes, you'll see this referred to as "refereed."
Publications that don't use peer review (Time, Cosmo, Salon) rely on an editor to determine the value of an article. Their goal is mainly to educate or entertain the general public, not to support scholarly research.
Most library databases will have a search feature that allows you to limit your results to peer reviewed or scholarly sources.
Different types of studies are considered to have different levels of quality of evidence. The pyramid below shows the general ranking of studies by the quality of evidence they are anticipated to contain.
