We are often asked about Google Scholar. It is a search engine that tries to act like a database. Instead of searching the free Web, it searches a collection of scholarly materials (journal articles, conference proceedings, …) It is one of many resources you have available to you, and may or may not be the best to answer your question.
Google Scholar provides another way to find references to scholarly material. GWU uses the FindIt@GWU Libraries link to take you to the full text of the item, if available.
