House of Representatives has compiled a A Citizen’s Guide on Using the Freedom of Information Act and the Privacy Act of 1974 to Request Government Records (HR Report 109-226).
From section IV, How to Use this Guide:
This report explains how to use the Freedom of Information Act and the Privacy Act of 1974. It reflects all changes to the laws made since 1996. Major amendments to the Freedom of Information Act passed in 1974, 1986, and 1996. A major addition to the Privacy Act of 1974 was enacted in 1988.
This Guide is intended to serve as a general introduction to the Freedom of Information Act and the Privacy Act. It offers neither a comprehensive explanation of the details of these acts nor an analysis of case law. The Guide will enable those who are unfamiliar with the laws to understand the process and to make a request. In addition, the complete text of each law is included in an appendix.
