Referencing

This is mostly just for me, but The Nuts and Bolts of College Writing has an exhaustive page detailing how to reference just about everything. I was looking for info on how you footnote a quote from the US Constitution, and found not just that, but a whole lot of other useful stuff. Well worth a look if you use the Chicago style of referencing for your essays, and you don't own a copy of the Chicago Manual of Style!
