Bias refers to how an author may be prejudiced to favor or oppose something. Ask yourself the following questions to determine if the information source is neutral or opinionated:

• Does the resource cite its sources?
• Does the resource advertise products or services?
• Does the resource try to educate readers, sell them a product, or provide balanced information?

Analyze the content of the information source to help you evaluate if it will help you with your assignment. Think about the following questions:

• Does the information source meet all of your professor's requirements; for example, is the source a peer-reviewed article?
• To what extent is the resource connected to your research question?
• Will this resource help you make a recommendation at the end of your report? 

When you are evaluating an information source, use the following questions to help you determine if the information presented is current:

• Does the resource have a publication date? Keep in mind, the publication date may be different from the copyright date.
• Does your instructor require you to use a source that was written within a specific time frame such as the past five years?
• Does the age of the resource affect the strength of your argument or recommendations?
