When you start a research project, you need to understand the background of an issue.
Maybe you want to start your background search with Google or Wikipedia. If so, remember to treat them both as starting points not as definitive sources. Although it is much more reliable than in the past, Wikipedia alone is not a good source and faculty do not like to see it cited. Start with Wikipedia if you wish and then check "External links" at the bottom of the page to verify information.
