Google Scholar is a time-saving, scholarly search interface. With Google Scholar, you can locate scholarly journal articles, books and book sections. For literature searching, specialized databases have more functionality and access more comprehensive results, but Google Scholar is a good tool to use for a search for a known item.
The next time you search scholar.google.com, the GetIt at NYU option will be available next to accessible article citations.
