Google Scholar looks a lot like "regular Google," but it only includes scholarly publications, mainly articles. It includes some (not all) of the articles you may find using the Libraries research databases, so use it in addition to databases.
Full-text access to many materials in Google Scholar is not available to everyone. Instructions for setting your Scholar preference, so that full-text links from Purdue Libraries will show up in your Google Scholar results, can be found on the Off-Campus Access webpage.
