Types of Sources

In order to be successful you will need to know how to identify a peer-reviewed or "scholarly" source. These videos can help you learn the difference between the different types of sources, can help you identify the differences between primary and secondary research, and introduce you to the different types of data. This page also provides information on important questions to ask as you determine the quality of the sources you find.

When looking at an information source, try asking yourself the Five W's. 

  • Who? Who wrote this? Can you even tell? Are they an authority in this topic? Credentials are important, but first-hand accounts are also important. Most importantly, who stands to benefit if you believe this source?
  • What? What kind of resource is this? Is it an advertisement? Newspaper article? Scholarly research article? Also, what kind of information does it present? Does the content match up with what you already know about this topic? Are there a bunch of advertisements, either related or unrelated to the topic of the article?
  • When? How up to date is the information? And how soon after the event was this published? (We've all seen false reports and misinformation happen shortly after major events like school shootings.) Also, how up to date do you need the information to be? Looking for reviews of classic movies that came out shortly after the cinematic debut versus critical acclaim that came years later can make a big difference.
  • Where? Country of origin?  How different is the information provided by CNN versus BBC versus Al-Jazeera? Also, where is this information in relation to the structure of the website? Is it on the front page? Is it buried?
  • Why? What's the purpose of the source? Is it trying to sell you something? Convince you of something? Also, why are you looking at this source? Entertainment? Medical research? Academic need?

Currency: the timeliness of the information

  • When was the information published or posted?
  • Has the information been revised or updated?
  • Is the information current or out of date for your topic?
  • Are the links functional?

Relevance: the importance of the information for your needs

  • Does the information relate to your topic or answer your question?
  • Who is the intended audience?
  • Is the information at an appropriate level (i.e. not too elementary or advanced for your needs)?
  • Have you looked at a variety of sources before determining that this is one you will use?
  • Is this source appropriate for a research paper?

Authority: the source of the information

  • Who is the author/publisher/source/sponsor?
  • Are the author's credentials or organizational affiliations given?
  • What are the author's qualifications to write on the topic?
  • Is there contact information, such as a publisher or e-mail address?
  • Does the URL reveal anything about the author or source?
    • examples: .com (commercial), .edu (educational), .gov (U.S. government), .org (nonprofit organization), or .net (network)

Accuracy: the reliability, truthfulness, and correctness of the content

  • Where does the information come from?
  • Is the information supported by evidence?
  • Has the information been reviewed or refereed?
  • Can you verify any of the information in another source or from personal knowledge?
  • Does the language or tone seem unbiased and free of emotion?
  • Are there spelling, grammar, or other typographical errors?

Purpose: the reason the information exists

  • What is the purpose of the information? To inform? Teach? Sell? Entertain? Persuade?
  • Do the authors/sponsors make their intentions or purpose clear?
  • Is the information fact? Opinion? Propaganda?
  • Does the point of view appear objective and impartial?
  • Are there political, ideological, cultural, religious, institutional, or personal biases?

By scoring each category on a scale from 1 to 10 (1 = worst, 10=best possible) you can give each site a grade on a 50 point scale for how high quality it is!

45 - 50 Excellent | 40 - 44 Good | 35 - 39 Average | 30 - 34 Borderline Acceptable | Below 30 - Unacceptable
