What is information? Who are the information rich and who are the information poor? How can there be equality of access for users in the light of the political, economic and cultural pressures that are placed upon information creators, gatherers and keepers? Set against a broad historical backdrop, The Information Society explores the information revolution that continues to gather pace, as the understanding and management of information becomes even more important in a world where data can be transmitted in a split second. This latest edition of this standard work has been fully updated to take account of the changing landscape and technological developments since 2008. The social Web, or Web 2.0, is now embedded in daily life, and some of its applications have become the most popular forms of communication system. Even the predominance of email – one of the most familiar manifestations of the information revolution – is now threatened by texting and the use of such applications as Twitter. The ways in which we expect to interact with information – and how much we are willing to pay for access to it – are throwing up new opportunities and debates.
