Google Research

Something new is available in Google Docs! This is groovy. Once you open your document, you can go to Tools>Research and a search window will pop open on the right side of the screen.

You can search right there, while you are working on your document!

Then hover your mouse over the source on the right and you will see options to preview the source, Insert a link to the source, or get a citation for the source.
