I learned of a new search engine to get at information from the federal government. It is in beta but may be some use and interest to you. Here is how the site describes itself:
Welcome to the first phase of LOUIS - the Library Of Unified Information Sources, a project of the Sunlight Foundation, and an effort, to paraphrase Justice Louis Brandeis, to illuminate the workings of the federal government. Our ultimate goal is to create a comprehensive, completely indexed and cross-referenced depository of federal documents from the executive and legislative branches of government. We are not there yet, but we can now offer these documents organized in a user-friendly interface, with a powerful search engine.I have had no time to really play with it but if you, please feel free to leave something in the comments section. Here is the link to the site.
