Understanding the purpose helps to see if there are any biases that may affect the way the information is presented.  

It's important to ask:

• What are the aims of the material? To inform? To persuade? To add to the field of knowledge?
• Is this information clearly biased in one way or another? 
• Does this source present multiple points of view on the topic?
• Is the language used meant to evoke a strong emotional response? 

Additional Internet Consideration:
