Use Google to Locate Government Documents.
Google is a powerful way to access government documents posted online. If you know what you're looking for, customize your Google search: Use "site:.gov" to precede your search terms to find government agency sites that pertain to your topic. Placing your search terms in quotation marks may help as well.
