Determining the Reliability of a Resource

Not sure where to begin?

We recognize that many students will begin their search by performing an internet search for their topic.  So, let's learn how to determine if the information you find on the web is appropriate to use in your research. 

  

Let this be a beginning step in your research, not the only step.

Is the resource you've found on the web a good resource?  How can we tell?

  • Use the SIFT method to determine the credibility of information found on the web.
    • Stop - do not engage with the text until you get enough context about the text to determine if it is worth engaging with.
    • Investigate the source -
      • who is the author? 
      • what is the purpose of the source?
      • is it possibly written with a bias?
      • has it been reviewed and approved by experts in the field of study?
    • Find better coverage - find other resources about the topic from reliable sources.
    • Trace claims, quotes and media to the original context - backward searching.

Why might an Internet search be a good place to start? Discovery 

  • Learn the basics about your topic
  • Use what you have learned to inform your research.
  • Create a list of keywords related to your topic.
  • Develop your keywords in relation to what you want to learn about your topic.
  • Use the library's databases to provide direct access to academic, peer-reviewed materials.

What makes a good resource?

Relevancy - Does this source deal specifically with your topic?

Scope - Does this source only mention your topic briefly or does a substantial portion of the resource discuss your topic?

Currency (as applicable to the topic) - When was this piece written? Does the age of the source affect its relevancy to your topic?

Credibility/Reliability - Who is the author?  Do they have the authority to speak about this topic?  What are the author’s credentials?  Has this resource been reviewed by other experts in this field of study?  

Purpose - Informative vs. Persuasive. What is the intention of this source? Is the author trying to persuade you or is the author presenting information? Is there a bias you should be mindful of?

When choosing a resource, it is important to determine the credibility and reliability of that resource.
To do that, we recommend the C.R.A.P. test: 

Currency 

  • What is the publication date?
  • and how does this date impact your topic of research?
    • Remember, newer doesn't always mean better.  The need for currency depends heavily on the topic of your paper. 
    • If you are evaluating a website, the publication or copyright date will help you determine if the site is current.  If you can't find a date on a website, beware; the information on the site might very well be out-of-date.  Broken links are another sign that the site has not been updated recently.  

Relevancy

  • Does this resource actually deal with your topic?  
    • Be careful that you aren't choosing a resource just because it has your keyword somewhere in the title or contents. Make sure the work has a substantial portion that directly addresses your research topic.
    • Ask yourself, "Does the resource primarily deal with the topic I am researching?"

Authority/Accuracy

  • Who is the author of the resource?  
  • Do they have substantial academic or professional experience and credentials that give them the authority to speak on this topic?
  • Does the resource provide references for the included information?
  • Was the resource published by a reputable organization?
  • When you are evaluating a website, web addresses that end in .gov and .edu are typically more authoritative than .com sites.  

Purpose/Point-of-view

  • Why was this resource written?  To inform?  To persuade?  
  • Consider the sponsoring organization associated with the resource. 
  • Be aware of any bias that the author may have toward your subject that could taint the authority and reliability of the information provided in their work.

 

Sources are divided into two main groups; primary and secondary.  

  • Primary sources provide a firsthand account or insider's look at a specific person, a specific time period, or a specific event.  If a primary source could speak to us it would say, “I was there; this is my experience or my experiment.”  Examples of primary sources include diaries, personal journals, autobiographies, memoirs, personal correspondence, interviews, speeches, newspaper articles or news footage from a specific time in history, official records, original photographs, creative works such as plays, poetry, music, or art, and also original research data.  Primary sources can be documents, photographs, film or video footage, and objects/artifacts. Please note that primary source does not necessarily equal factual source.  Primary sources provide firsthand accounts of an event, experience, or experiment.  It is up to you, the researcher, to evaluate each of those accounts individually to build an informed, knowledgeable, and well-rounded assertion about your topic.   

 

  • A secondary source is an interpretation or analysis of one or more primary sources.  If a secondary source could speak to us it would say, “I wasn’t there but I have studied the topic and these are my thoughts on the matter.”  Examples of secondary resources include such publications as biographies, commentaries, criticisms, textbooks, articles, and critical essays.  

Example:   

       

The first book on the left, I am Not Spock, was written by Leonard Nimoy and is his personal account of his experiences of portraying the character of Spock in the television series Star Trek.  The next book, Star Trek: Movie Memories, was written by William Shatner who portrayed the character of Captain James T. Kirk and discusses his experiences during the creation of the Star Trek films.  Each of these sources says to us, "I was there; this is my experience."  These are primary sources.

The last book, Star Trek as Myth, is a collection of essays about Star Trek.  This book is comprised of the different authors' interpretations and analysis of the mythology of the television series and films.  This book says to us, "I wasn’t there, but I watched Star Trek and these are my thoughts on the matter."  This book is a secondary resource.

Peer-reviewed simply means that the article’s content has been checked by other experts in that specific field of study for accuracy and reliability.  These resources are also often referred to as scholarly articles or academic articles.

5 Clues that the article is peer-reviewed:

  1. References – always look for a list of works cited, a bibliography, or a reference list
  2. Author – educational and professional credentials provided
  3. Abstract – a short summary highlighting the content of the article
  4. Audience – content written using specialized terminology
  5. Graphs and Charts – visually communicated empirical data
