The official website for the United States Senate features a list of all the current senators. The list is in alphabetic order and includes the address, phone number and other contact information for each senator.
The list of senators is sortable by the name, state or party of the senator. The site also lets a user narrow the list down by state, name or class. The names of each senator on the list are also hot links that lead straight to the senators' websites. The site also features an organizational chart that includes pictures of the senators and information about each senator's standing in the Senate.
