Access to Government Information
This section of the legal guide outlines the wide-array of information available to you from government sources. These sources range from your local city council all the way up to the largest agencies in the federal government. In fact, you might be quite surprised at how much information is available to you. And the best part is that you generally don't need to hire a lawyer or file any complicated forms -- you can access most of this information simply by showing up or filing a relatively simple request. Moreover, you don't need to be a professional journalist to share what you find with others who are interested in these issues; with nothing more than an Internet connection, you can make the information available to anyone in the world.
