To Use Or Not to Use?

"My professor says I can't use Web sources for my paper."

Ask your professor to clarify this, because there are basically 'two Webs.' There is the public Web that search engines find, and there's the "invisible Web," Web sources that search engines cannot pick up, which include resources that libraries such as Chabot purchase and make available such as online subscription databases.

An article you find using a periodical database such as EBSCOhost Academic Search Premier also exists in a journal in print. It's just delivered via the Web by the library to facilitate research.

If you still have questions, please contact the Library or get a clarification from your instructor.
