What are primary sources in science?

MLWGS science teachers sometimes require students to consult scholarly, primary research about a topic in order to develop a hypothesis, design an experiment, or write a persuasive paper.  To be considered a primary source in the sciences, an article must convey original research findings made by the scientists who wrote the article.

What is Original (Primary) Research?  (concise answer and glossary from UNF Libraries)

Here’s a quick video tutorial from Hartness Library System in VT that explains how to distinguish between primary and secondary sources too:
Traits of primary (original) research articles
Some common traits (not all of which are mentioned in the video) include the following:
  • Discusses experiments or modeling the researchers conducted themselves
  • Has sections like materials, methods, results, and conclusion/discussion/analysis
  • Includes charts, diagrams, tables, and data sets of original data
  • Has a lengthy reference list
  • Uses a formal, technical writing style
  • Has a title that describes experiment/findings (versus one that sounds like a catchy headline)
  • Authored by a team of scientists with expert credentials

Examples of primary and secondary sources

  1. Primary source (open web) – research study – UC Irvine
  2. Primary source (Gale) – research report – Coastal Education and Research Foundation
  3. Secondary source (JSTOR) – news article found in scholarly database
  4. Secondary source (found with Highwire) – review article

Finding Primary Research Articles

Many sources in the Delving Deeper list below may contain primary research about your topic.  As you budget your time, remember that you can only access full-text articles in Science Direct while on campus.  When you search Science Direct, use the Journal Search (click Search on the top toolbar, then click the Journal tab of the search box) and limit your search to the last five years.  For the most features, view the HTML version of the article (by clicking on the article title in your search results list rather than the PDF icon).  Features available in the HTML version include related articles, related terms, hyperlinked reference lists, quick access to figures and tables, and more.

See the section below that reviews important search limiters in Science Direct.

Reading Research Articles

How to Read a Scientific Article (PDF) – once located, reading scientific articles can be a challenge.  To improve your reading, use this method from Mary Purugganan, Ph.D., and Janice Hewitt, Ph.D..
Are you a visual learner? Here’s a reading tips video (best viewed full screen) for scientific articles. There’s no audio, but it covers useful information.

Setting Limiters in Science Direct

Our subscription only includes journals for the most recent five years. To avoid muddling your search results with articles to which you do not have full-text access, open Advanced Search, click on the Journals tab, and set the date to begin five years ago (e.g. in 2017, with 2012). To increase the chances that the articles will be primary research articles, further limit to Articles instead of other document types.
