What are Scholarly/Academic/Peer-reviewed Sources?

Scholarly/academic/peer-reviewed sources are sources written by experts and are reviewed by experts in the field before the article is published.

Why Do I Need to Evaluate Scholarly Sources?

You may consider scholars with subject expertise have authority in the area of your research topic and thus produce only good sources. However, like all types of sources and authorities, scholarly sources vary a lot by date, scope, method, and etc, making only some of them appropriate to cite in your research. Scholarly sources may have totally valid evidence but not so relevant to your research. 

How Do I Evaluate Scholarly Sources?

Finding a good scholarly source to use can sometimes be a messy process, but below are some questions you can ask yourself in order to determine if the academic article is worth using in your research.

• Date: Some topics, such as those in the health sciences, require current information. Other subjects, such as geology, value older material as well as current. Know the time needs of your topic and examine the timeliness of the article; is it:
  • up-to-date,
  • out-of-date, or
  • timeless?
• Usefulness: Is the article relevant to the current research project? A well-researched, well-written, etc. article is not going to be helpful if it does not address the topic at hand. Ask, "is this article useful to me?" If it is a useful article, does it:
  • support an argument
  • refute an argument
  • give examples (survey results, primary research findings, case studies, incidents)
  • provide "wrong" information that can be challenged or disagreed with productively
• Impact: Scholars have combined standard research metrics, like scholarly output and citation counts, into formulas to measure and assess author and journal impact in new ways. There are usually different types of metrics for different purposes, but in general, you can pay attention to
  • the number of times an article was cited to evaluate the scholarly output of a scholar
  • the number of times articles published for a journal to evaluate the impact of a journal
  • metrics in databases as shown below

Internet Resources

Internet resources can be even more challenging to evaluate because dates and authors are not always readily available. Plus, we all know that anyone can create a website. The following are some important things to consider when reviewing internet sources. 

Who Created the Information?

Websites do not always have authors so you'll need to find information on who or what organization is responsible for creating and updating the webpage. The following are links to look for on webpages that should provide more information on who is behind the website.

• "About Us": usually provides information about the organization or company that is responsible for the webpage.
• "Mission Statement": this will provide information on what the organizations values or goals are. 
• "Contributors": provides information on who contributes content to the website, sometimes they'll even list the qualifications of their contributors. This section may also provide information on who funds either the website or the organization. *Beware of websites like Wikipedia where anyone can create an account and edit webpages.

Publication Dates

Finding the date a website was created or last updated can be difficult sometimes. If you can't find a date on a particular webpage, click around and look at the other resources on their website, can you find a date anywhere? Are there links to other sources that are out of date or dead links?

URL Domain Extensions

The following is a list of the most popular domain extensions, which can be used to help determine authority and objectivity. However, domain extensions alone cannot determine if a web source is quality or if it's right for your research.

.gov - Government. The intent of the site is to present official information collected by or about the workings of a government.

.edu - Educational institution. The intent of the site is to educate as well as present information collected by or about the educational institution. *Look out for student work or papers that haven't been published in an authoritative source.

.com - Commercial. The intent of the site is to sell goods or services, as well as provide information about the company.

.org - Organization, usually non-profit. The intent of the site is to present information collected by or about the organization. Sometimes, the intent of the site is to promote a particular point of view. *For more information about the organization check out Idealist.org. 

.net - Network, usually personal Web pages. The intent of the site is as varied as the individual(s) responsible for the content. *Usually not scholarly in nature, so if it is a personal page then make sure you research who that person is and what their qualifications are.
