Google Scholar provides a simple way to broadly search for scholarly literature on the open web.
BEWARE: Because Google Scholar is an open web search, you are unable to limit to "scholarly/peer-reviewed" literature as you can in a library database. Be sure to evaluate resources before using for your course research.
TIP: First, search library databases for scholarly literature. Second, use Google Scholar if an article it is not available in full-text through a library database.
