The independent web developers of this 2.0 world have done a great job in making federal legislative information available in new ways; see GovTrack.us andOpenCongress.org for examples. The same is happening with federal regulatory information. New, free, nongovernment resources have come online to complement the official U.S. government regulatory information sites, RegInfo.gov andRegulations.gov. For this bounty, we can thank innovative developers and the relatively new availability of a free XML version of the Federal Register that can be downloaded in bulk. The Federal Register has long been available for searching and viewing for free, but subscribing to the data in bulk–necessary for meaningful repurposing–carried a cost that discouraged entrepreneurial individuals. In the meantime, both RegInfo.gov and Regulations.gov have been redesigned and continue to provide content and functionality not available on the other free sites mentioned in this article.
