Google Scholar focuses on the scholarly literature available on the Internet. This includes, articles, theses, books, abstracts, U.S. court opinions, and patents, found on the websites of academic publishers, professional societies, online repositories, universities and more.
Links to the full text will display if you begin the search from the list of library databases and if the Consortium Library subscribes to the journal title, or if it's from an open access journal, or if the researcher posted the article on her/his website.
Google has a broader scope and looks for all information found on websites.
Google uses a program to identify scholarly works, not a real person. So be careful and double-check that what you find is in fact scholarly.
