The Free Web is made up of web pages you can find using Google and other Free web search engines. Some assignments do not allow free web resources. Good material may be found here, but also a lot of information that may be inappropriate for academic writing. Evaluate carefully!
The Fee Web (also known as the Hidden, Invisible, or Deep Web) includes subscription databases. You'll usually find better information here--including those scholarly and peer-reviewed articles often required--since most database content went through a more rigorous publication process.
