First, check with your instructor!
If you are planning to "google" the Web for your research, any sources that you find should be authenticated. The sites you locate might contain deceptive, biased, or incorrect information. It will be your job to determine which information meets the rigors of academic research. For this reason instructors and librarians often encourage you to use only the library's Web resources, where much of the authentication has already been done for you.
Wikipedia is a free online encyclopaedia containing millions of articles. Anyone can write and edit the articles. It's a great place to start looking for information, but it's usually not acceptable as an information source for academic work.
Ask your instructor if Wikipedia is appropriate for your assignment!
You may have grown up with the Internet and feel very confident using Google or Wikipedia. But, do you really know how to conduct academic research on the Web?
You can find some great information out there, but using the Web for academic research requires diligent evaluation.
