Once you have gathered and evaluated all of your information sources, the final question to ask is if the information you found satisfies your research or information need.

Think about your information need and your topic question.

Have you answered it sufficiently?

Does the information you found provide enough evidence to support your thesis?

Are there gaps in the information you retrieved?

Do you need to revise your search strategy or your terminology to gather more support for your thesis or topic question?

Do you need to change your topic altogether?
