Types of Sources

There are three main types of publications that may appear in the advanced search results of many social and behavioral sciences databases. These are:

  • Scholarly sources -- intended for use in support of conducting in-depth research, often containing specialized vocabulary and extensive references to sources. The content has been reviewed by academic peers to ensure the reliability of methods used and the validity of findings. Scholarly sources help answer the "So What?" question in academic writing and lay the foundation for discovering connections between variables, issues, or events.
  • Popular sources -- intended for a general audience of readers and are written typically to entertain, inform, or persuade. Popular sources help you answer who, what, when, and where questions and are essential for finding information about current events or issues. Popular sources range from research-oriented [but lacking complete citations to sources] to special interest, agenda-driven publications.
  • Trade publications -- intended to share general news, trends, and opinions among practitioners in a certain industry or profession. Although generally written by experts, they are not considered scholarly because they do not focus on advancing new knowledge discovery or reporting research results and are not peer-reviewed. Trade journals, however, are an essential source of information in the field of business and specialized industries [e.g., tourism, environmental studies, agriculture, etc.].

Scholarly Journals versus Popular Publications

Below is a chart developed by the USC Libraries instruction team that can help you distinguish between a scholarly [a.k.a., peer-reviewed or academic] journal article and a popular, general interest publication. Note that trade journals are an important type of resource in business and industry intended to inform practitioners and professional leaders about current news and trends in a specific area of manufacturing, service, or other trade activity. They are not considered scholarly because the articles are not reviewed by scholars before publication.
