Here is a new tool that we can send our students (and ourselves to) - Google Scholar!
From the website: What is Google Scholar?
"Google Scholar provides a simple way to broadly search for scholarly literature. From one place, you can search across many disciplines and sources: peer-reviewed papers, theses, books, abstracts and articles, from academic publishers, professional societies, preprint repositories, universities and other scholarly organizations. Google Scholar helps you identify the most relevant research across the world of scholarly research. ... It's our acknowledgement that much of scholarly research involves building on what others have already discovered. This invitation is taken from Sir Isaac Newton's famous quote, 'If I have seen further, it is by standing on the shoulders of giants.'"
