Honors 301: The Symposium: Primary & Secondary

Spring 2015 -- Dr. R. Anderson

What is a primary source?

"Primary sources are original materials/information on which other research is based. It includes journal articles of original research, conference papers, dissertations, technical reports, and patents. Primary sources are also sets of data, such as health statistics, which have been tabulated, but not interpreted."

-University of Minnesota Bio-Medical Library. (2010). Primary, secondary, and tertiary sources in the health sciences.

It's probably primary if...

...it presents new research. Look for a description of methodology - did they create new data, or are they examining data generated by other people or groups?

...tries to address a specific question. Are the authors finding an answer, or providing an overview?

...contains "raw data". Does the article present information directly (ie. tables, graphs), or does it only describe the information collected?

It's probably secondary if...

...it reviews data produced by others. Look for terminology such as "overview", "meta-analysis", or "literature review"

...provides a broad overview of a field. If it's not addressing a specific question, it is often a summary of work performed by others.

...provides a personal view. Editorials, analysis, responses to articles, and such - while these are often useful, they aren't presenting unbiased information that can be used by other parties without examination for bias.

If you'd like a refresher on what qualifies as a primary source, the American Journal of Nursing has provided guidelines as used by authors submitting to the journal.
