Here is a good, basic formula for getting started with your research:
Both scholarly and peer-reviewed articles are written by experts in academic or professional fields. Scholarly articles are published in journals for specific academic disciplines. Many scholarly journals are also peer-reviewed.
Peer-reviewed articles are submitted to reviewers who are experts in the field. Because the reviewers specialize in the same scholarly area as the author, they are considered the author’s peers (hence “peer review”).
Both scholarly and peer-reviewed articles are excellent places to find what has been studied or researched on a topic, as well as find references to additional relevant sources of information.
Popular sources are written for a general audience and are intended to inform readers on a broad range of topics, such as news events, topics of current interest, and the business and entertainment worlds. Examples include newspapers, magazines, best-sellers, and consumer-oriented websites. They can be useful for getting ideas for a topic or for background information. When used to document historical events, cultural practices, or public opinion, popular sources may be valuable to researchers as primary source material.
