Finding Reliable Information Sources: How to Evaluate Sources

A guide to finding reliable sources and evaluating the information they provide.

Evaluating Data & Statistics Guide from University of Washington Libraries

The University Libraries at University of Washington has created a research guide to help determine the reliability of data and statistics. As one of the easiest types of information to manipulate to suit any agenda, it's important to evaluate statistical information and sources before you believe, use or share. The UW Libraries have developed SMART evaluation criteria to help:

The News Literacy Project

Using the ACCORD Model and CRAAP Test for Evaluation

You can evaluate your sources for news and information by considering the following points:

  • WHO (the source author's authority/credentials):
    Who wrote/published/sponsored the item? What are their credentials/background?
    • Look at the website’s “about us” page or search for a bio or other information about the author
  • WHEN (the date of the article or when it was written):
    How recently was it published? Has information about this topic changed or been updated?
    • Look for timeliness to the topic and to information that developed about the topic
  • WHERE (the URL or the article's citations or references):
    What’s the web address? Where is this source getting its information? What sources is it referencing?
    • Look for evidence or supporting information; notice if the resource cites references, and check them
  • WHY (the purpose of the article or website):
    Why or for whom was the information published? Is it objective or is it propaganda? 
    • Look at language (inflammatory, persuasive, neutral); look for intent (to teach, sell, or entertain)
  • HOW (the bias or perspective present):
    How is this information presented? Is there clear bias present? ​
    • Look for any political, cultural, or religious opinions or prejudices; take note of any sponsoring organization
  • Can the information be confirmed? Confirm it in at least two reputable sources!
