Understanding Scholarly Sources

Peer Review in 3 Minutes

Superb 3-minute video by North Carolina State University Libraries on peer review, the process of determining whether an academic paper is suitable for publication in a scholarly journal.

PRIMARY SOURCES

-Report the results of experimental research
-Authored by the scientists conducting the experimental research
-Are usually the first appearance of experimental results
-Can comment on or respond to the work of other authors but must still contain substantive original content or experimental research
-Can include informal communication between researchers through email or presented at conferences

Examples:

  • Research articles* in scholarly journals
  • proceedings of meetings, conferences, and symposia 
  • dissertations 
  • technical reports
  • patents
  • data sets that haven’t been interpreted yet

Sample citation:  Nowinski, N., S. Trumbore, E. Schuur, M. Mack, and G. Shaver. 2008. Nutrient Addition Prompts Rapid Destabilization of Organic Matter in an Arctic Tundra Ecosystem. Ecosystems 11:16-25.

 

*Research articles present original results of a single study or experiment and are divided into sections with headings such as Abstract, Introduction, Materials and Methods, Results (with tables & figures), Discussion, References (Literature Cited). Scientific research articles are usually published in scholarly journals produced by learned societies (e.g., Ecological Society of America) or by commercial publishers (e.g., Elsevier, Wiley, Springer). Researchers submit an article to a journal. It is then refereed by an editorial board of experts in that field before being accepted or rejected for publication.

SECONDARY SOURCES

-Interpret, analyze, evaluate, and/or summarize the information reported by researchers in the primary literature, usually in an attempt to identify trends or draw broader conclusions

Examples:

  • Review articles*
  • Books
  • Magazine & newspaper articles (may also be primary)
  • Textbooks
  • Data compilations

Sample citation: Danovaro, R., P. V. R. Snelgrove, and P. Tyler. 2014. Challenging the paradigms of deep-sea ecology. Trends in Ecology & Evolution 29:465-475.

 

*A review article summarizes the results of several studies or experiments. Its author(s) is not the author(s) of most of the literature reviewed. Review articles appear in journals with titles such as:  

Annual Review of _____
Current Opinion in _____
Nature Reviews
Trends in ____
