I feel that right now is about the time that the majority of us are working of essays, papers, research, etc. So to make stuff eaiser, I'll give you this gift: a site that does all kinds of citations for you. http://citationmachine.net/index2.php?start=# This thing's really saving my ass right now. It's not an advertisement, i'm just offering help for others.
I just use the Reference tab in Microsoft Word. Then Manage Sources, set it to MLA, and then there's Insert Citation. Of course, you have to edit each citation with page number yourself, though, but it makes your works cited for you, lets you know which sources you've yet to use, and everything. Just make sure you fill in all possible info and fill it in right (i.e., put quotes around article titles; it won't do that for you.)
