Periodical is a term used to describe any publication that is published multiple times (periodically). Periodicals include materials such as popular magazines, scholarly journals, and newspapers.
It is important to understand the difference between a popular and a scholarly periodical. When you are doing research, most of your sources should be scholarly.
Often popular periodicals are called magazines and scholarly periodicals are called journals. Many times it will be acceptable to use some popular material, but research papers should not be based solely on popular literature.
