The folks at People For the American Way have set up this handy website  that practically writes a FOIA request for you. All you have to do is print and fax. Of course, whether and when the feds get back to you is another matter. 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.
Speaking of FOIA requests, Tom Hayden gave a talk up here in Saratoga Springs on Monday. While I quibbled with his choice of title Democracy or Empire: You Choose -- since US imperialism past and present may well go by the slogan Democracy AND Empire: No Choice -- he did launch into a fascinating digression on the contents of his voluminous FBI file. The most chilling words contained within: "How do we neutralize Hayden?" (At which point a colleague mumbled, "Give him a tenure track job.")
If anyone comes up with similar results let us (and your lawyer!) know.
