The folks at People For the American Way have set up this handy website that practically writes a FOIA (Freedom Of Information Act) request for you. All you have to do is print and fax.

The Justice Department maintains that simple requests take an average of 19 days, while complex ones can take up to a year -- though I've heard of journalists waiting much longer for their results.
