Google Scholar provides a simple way to broadly search for scholarly literature.
From one place, you can search across many disciplines and sources: articles, theses, books, abstracts, and court opinions, from academic publishers, professional societies, online repositories, universities, and other web sites.
Google Scholar aims to rank documents the way researchers do, weighing the full text of each document, where it was published, who it was written by, as well as how often and how recently it has been cited in other scholarly literature.
Google Scholar's motto 'Stand on the shoulders of giants' is derived from Sir Isaac Newton's statement: "If I have seen further, it is by stand on the shoulders of giants."
That phrase is our acknowledgment that much of scholarly research involves building on what others have already discovered.
