"Google is always looking for ways to enhance user experience and they are particularly good at integrating more tools into their existing products. This time they are offering some useful refinements to Google Docs. If you’re a researcher you’re gonna love this.
Now when you are composing in Google Docs you will have access to a research pane which can bring up information relevant to what you are writing about. So if you are writing a paper about George Washington and you forgot to document a fact about his life, all you have to do is go into tools and bring up the research pane."
I have tested this tool and it allows you to quickly find additional information without leaving the document you are working on. For many students this would prove valuable.
