This guide explains primary and secondary sources and provides information specific to the three styles used most at MUSC- AMA, APA, and Vancouver; specifically:
Defining what primary and secondary sources are to distinguish and identify sources by their characteristics.
Determining the most appropriate source type for your research that is needed to provide the best possible support for your argument.
A primary/secondary source in the humanities or social sciences will look different from a primary/secondary/tertiary source in the sciences or medicine or nursing research, Quality improvement, or clinical practice. The purpose of how one will use the information like the topic will drive which category a source is categorized.
Tertiary sources provide overviews and context, like textbooks, or point of care search engines ( e.g. DynaMed, UpToDate, and StatPearls.) It is a great starting point to familiarize oneself with a topic and may include references to specific research articles. Tertiary sources can also be used as a citation in a paper depending on the context of the paper; however, in clinical practice, it is preferred that one uses primary and secondary sources to support clinical decisions.
