A periodical is a publication that is usually issued on a regular schedule, e.g. daily, weekly, monthly, or quarterly. Periodicals usually have dates and volumes/issue numbers. Examples of periodicals include newspapers, popular magazines, and scholarly journals.
When embarking upon a research project, college students may be required to use a wide variety of sources, depending on the professor's requirements. Often students must use only scholarly journal articles. Other times, news and other popular periodical articles may be appropriate. Determining whether or not an article is scholarly or popular can be challenging. This guide includes examples, images, and a video to help students learn to differentiate between types of periodicals. If there is any uncertainty, librarians are available at the library reference desk during these hours, and by email and chat.
