There is no short answer to this question. You can certainly find some information in library databases that is not reviewed by experts -- something from a newspaper opinion column, for instance. But a large majority of the information is in some way evaluated or reviewed for quality. That's why it's in the database and why the librarians have selected it as a resource for students.
However, as with any question, there are rarely black and white answers. I highly recommend looking at our tutorial, Begin Research, specifically the section on the Knowledge Cycle and Discovery Tools. These will help you better answer this question, as well as any others you might come across in your assignments.
