Ryan Alcock's MLA package
Ryan Alcock authored a package that makes typesetting MLA format papers in LaTeX a snap. Little preamble and very easy to use.
Here's the link to Alcock's style file. Copy the whole page, paste into a text editor and save as mla.sty. Once that's done, you can always invoke the package in your document.
MLA Template
Here's my template for MLA papers in LaTeX. You can easily customize this and make changes to adapt to other formats. I discovered Alcock's package while doing this.
\documentclass[12pt]{article}
%
%Margin - 1 inch on all sides
%
\usepackage[letterpaper]{geometry}
\geometry{top=1.0in, bottom=1.0in, left=1.0in, right=1.0in}

\usepackage{setspace}
\doublespacing
%
%Babel package for multiple language typesetting

%\usepackage[english,german]{babel}
%\usepackage[T1]{fontenc}
%\usepackage[latin1]{inputenc}
%
%Setting the font

%To make sure we actually have header 0.5in away from top edge
%12pt is one-sixth of an inch. Subtract this from 0.5in to get headsep value
\setlength\headsep{0.333in}

% - from Ryan Alcock's MLA style file
%
