The Congressional Record is the official record of the proceedings and debates of the United States Congress. It is published daily when Congress is in session. The Congressional Record began publication in 1873. Debates for sessions prior to 1873 are recorded in The Debates and Proceedings in the Congress of the United States (1789-1824), the Register of Debates in Congress (1824-1837), and the Congressional Globe (1833-1873)

This book explores why some members of Congress are more effective than others at navigating the legislative process and what this means for how Congress is organized and what policies it produces. Craig Volden and Alan E. Wiseman develop a new metric of individual legislator effectiveness (the Legislative Effectiveness Score) that will be of interest to scholars, voters, and politicians alike. They use these scores to study party influence in Congress, the successes or failures of women and African Americans in Congress, policy gridlock, and the specific strategies that lawmakers employ to advance their agendas.
