Question: Why would you use Google Scholar?
Answer: Google Scholar identifies scholarly research materials from a broad range of subject areas.
Google Scholar lso offers a "cited by" feature - it will display a list of documents which cited the document you originally retrieved. This can be useful in determing how influential a source has been. The list only includes documents available in Google Scholar, though.
