The United States House of Representatives is one of the two chambers of the United States Congress; the other is the Senate. Each state receives representation in the House proportional to its population but is entitled to at least one representative; the most populous state, California, currently has 53 representatives. The total number of representatives is currently fixed at 435.[1] Each representative serves for a two-year term. The presiding officer of the House is known as the Speaker, and is elected by the members. This book concentrates on the Committees, Rules and Procedures involved in running this complex organisation.
