This month has seen major changes to two important resources for Congressional/legislative research.
ProQuest Congressional, one of Yale's subscription databases, has a brand new look. ProQuest Congressional provides full-text access to many different types of Congressional documents--bills, laws, the Serial Set, the Congressional Record, and more. Some of these materials are available back to the 19th century, which makes PQ Congressional an important resource for historical research, too. Check out the new search interface, and take a look at these helpful guides and webinars for more information about constructing great searches and finding the Congressional documents you need.
If you've ever used THOMAS (from the Library of Congress) to get access to the text of recent bills and other legislative documents, you'll want to know that THOMAS is going away in 2013. Its successor, Congress.gov, was released in beta on September 19, 2012, and while it doesn't yet have the full contents of THOMAS (see this guide that compares Congress.gov's coverage to that of THOMAS), these materials are being integrated into the new system.
Finally, if you're interested in following federal legislation and regulations--or legislation at the state level--have you tried Scout? This tool from the Sunlight Foundation provides easy access to the text of bills, regulations, and more, and if you create an account (it's free!), you can set up alerts to track the legislative and regulatory actions that interest you.
