This Document is an updated version of the IPU guidelines for parliamentary websites from 2000. The Guidelines published by IPU in 2000 helped many parliaments to set up or develop their website. Now almost every parliament in the world is present online. Today's challenge is to make the most effective use of the Internet to enhance the relation between parliaments and citizens. The new edition of the Guidelines offers guidance on how to use the key elements of a successful website – content, tools, design, and management – in the parliamentary context. The revised Guidelines take into account changes in technology and lessons learned since 2000, and have been prepared in cooperation with the United Nations and the Global Centre for ICT in Parliament.
