I found this link very useful when I needed to complete a workcited page. Being a college student I write many papers and it was easier just to go to this link and put in the information then looking in my MLA format book. Though I use both sometimes. Just though It might help someone else out. Happy Writing!!!!!!!
When I was writing my grad school thesis I found a little program that did the same kind of thing, but you could store your citation list and generate a formatted works cited section with selections from your list. I bet somebody has a Word macro to do the same thing and you'd never have to cut/paste.
