Google Scholar is another tool you can use to search for scholarly literature online. Google Scholar provides access to "peer-reviewed papers, theses, books, abstracts and articles, from academic publishers, professional societies, preprint repositories, universities and other scholarly organizations."
What Google Scholar does not contain, in most cases, is the fulltext of the articles -- but it does work with the library's Findit@VU service to help you get to the fulltext when available. If you are on campus, Findit@VU will automatically appear -- but if you are off campus it won't. Not clicking on Findit@VU may lead to you receiving a message indicating that you must purchase the article to view it.
Bookmark this link as your access point to Google Scholar to ensure that the Findit@VU links appears in your searches. Don't get caught paying for articles when you don't have to!
