In another article in these pages, we discuss how you can use the Freedom of Information Act (FOIA) to help get a leg up on the competition. We have found a number of FOIA-related sites that can help you navigate the FOIA process.
If you want a guide to the Freedom of Information Act, check out this site (http://www.usdoj.gov/foia/04_3.html). A word of caution, however: it's pretty dense reading, prepared as it is by the US Department of Justice.
The DOJ also has a page with links to other agencies' FOIA pages. This is a good staring point if you want to wade in to deeper waters. (http://www.usdoj.gov/foia/other_age.htm)
A commercial site The FOIA Group On-Line (http://www.foia.com). They offer assistance in preparing FOIA requests (for a fee). We get no referral kickbacks; we only offer it as a link.
And for those of you for whom the X-Files are more than just a slightly shopworn TV show, you can go to the Office of the Secretary of Defense/Joint Staff Electronic Reading Room Documents Concerning UFO's (http://www.defenselink.mil/pubs/foi/ufo/).
You can purchase both "The Roswell Report: Fact vs Fiction in the New Mexico Desert" and "The Roswell Report: Case Closed." Be warned, however; these were prepared by the US Air Force, so consider the source. . .
