There's an interesting website called governmentdocs.org that "was created to advance the values of open and accountable government." The site gathers government documents acquired through the Freedom of Information Act (FOIA) and other public disclosure laws and publishes them online. Once you register with the site (free registration) you can review and comment on any of the available documents, adding your "insights and expertise."
The website is a project of Citizens for Responsibility and Ethics in Washington (CREW). Thanks to Valerie Weiss, Faculty Services Librarian, for alerting me to this website.
