Google Scholar provides a familiar interface and method for searching scholarly literature across a wide array of disciplines and sources. You can find articles, theses, books, abstracts and other documents that are buried in Kresge Library databases or stored in academic institutional repositories around the world.
Google Scholar is not Google. Google Scholar is not searching the web at large, but a set of trusted resources that specifically focus on scholarly literature. Google Scholar is a good place to start to get a sense of where the scholarly literature on your topic is located.
You can also set Google Scholar up to link directly into the Library databases that you have access to as a Ross and UM student.
