Within the last decade more and more legal information has become available online. The same is true when it comes to federal agencies, which tend to contain all primary sources -- statutes, rules, and administrative decisions -- and extensive background analysis of those primary sources which define their function.

For example, let's take a tour of the US Environmental Protection Agency (http://www.epa.gov/). What types of documents are available on this site? Primary or secondary sources? What types of primary sources are available? Statutes? Cases? Administrative rules? What type of analysis?

The EPA website contains both primary and secondary materials. For instance, there are statutes, regulations, executive orders, administrative decisions, and position papers, as well as educational materials for children, and scientific studies. As primary materials, it contains links to statutes and regulations -- the EPA does not carry the actual statute or regulation on its website – it reroutes to FDSys. However, it does provide its own statutory summaries (see, e.g. summary of the Atomic Energy Act or the summery of the Clean Air Act (42 USC 7401 et seq.). The EPA site also contains all EPA regulations, which are easily located by following the Regulations link. Similarly, for regulations the site functions as a portal, rerouting users to various official and unofficial FR and CFR sites, such as the e-CFR. Perhaps the most difficult to find are the EPA administrative orders and decisions. The site covers the EPA's decisions since 1989 to date, but they are not easily accessible from the home page. The EPA decisions can be located through a Google search and then researched if you know the year of the decision and at least the name of one party.
