Copy and paste with citation, including Bluebook. You can paste text
into your work product with the official citations -- including The Bluebook, ALWD, California, New York and other leading formats.
It seems that if you "copy with reference" it will include a Bluebook citation by default, and you can choose other formats by clicking on the preferences option at the bottom of the screen. I am looking forward to seeing a live preview of the new interface!
