Google Scholar searches for references to scholarly articles and research papers. Sometimes the full text is posted online and linked, other times users will see a "Find It at Sac State" option next to the Google Scholar listing (see explaination above). For all but the most simple queries, using Google Scholar Advanced Search (click on the arrow in the Google Scholar search box to get Advanced Search Form) is recommended.
