Relevance has to do with the importance of the information for your specific needs.

Questions to ask [from Chico]:

• Does the information relate to your topic or answer your question?

• Who is the intended audience?

• Is the information at an appropriate level (i.e. not too elementary or advanced for your needs)?

• Have you looked at a variety of sources before determining this is one you will use?

• Would you be comfortable using this source for a research paper?

Additional Questions:

• Is the information credible or logical?

• Is there supporting evidence?
  
  • Is there a list of references used?
  • Are there links to other credible sources?

• Is it written in a style that you can understand?
