Research Tools: Evaluating Resources

Advice on Evaluating Sources

There are many different ways to evaluate sources and different
types of information require different evaluation categories. 
For example, you wouldn't evaluate a primary source you were
using in your History research task the same way that you would
evaluate a historian talking about the event afterward. 

Therefore, your Teacher Librarians have sorted through the various
methods of evaluation and list the ones we recommend below. 

Evaluating a Resource

The criteria to evaluate a resource: Currency, Relevance, Authority, Accuracy, Purpose and Bias.

Quick Tips

Ask Yourself:

1.  Who is the organisation behind the information?

2.  Is there an identifiable author?

3.  Can I find this information in two other reliable websites or books? 
     Cross-reference your information!

4.  When was this information last updated?

RESEARCH TIP! Ensure the information you are looking at is from a reliable source and is current. 

Look for information that is from the following:

  • A government website .gov
  • A Scientific website
  • An educational website .edu

Beware of information from forums and websites where people without qualifications are presenting information. E.g., Yahoo!Answers, and Wikipedia. 

Annotated Bibliography


  • Clear and concise annotation bibliography (Comment on the WHY you consider the resource to be reliable)


What makes a resource reliable?

  • WHO? From a reputable / reliable / authoritative source, e.g.  the government, a university, an expert in the area. Can you identify the author?
  • WHY? Try to determine the purpose behind the website: Is it to educate? To sell?
