The information age has become a reality, and has brought with it many implications for public administration. New ICT's offer new opportunities for government and governing, but at the same time they pose challenges in some key areas of public administration, like trust, or the idea of checks and balances.This book is an examination of the developments and effects of ICT in public administration over the last 10 to 15 years. It represents a re-visiting of the 1998 IOS Press publication 'Public Administration in an Information Age: A Handbook'. As a point of departure, the authors of this new book have chosen the speed of the succession of theoretical approaches, represented by the 'phase of theories' which has appeared since 1998. This approach, which reflects that of the 1998 handbook, avoids the impression of technological determinism and provides an opportunity to focus on the phases of theory and technological developments.The book is divided into five sections. The first section examines key issues, and the second focuses on aspects of democracy. In the third section, the focus shifts towards structural conditions; the conditions that public administration has to meet in order to maintain its effectiveness and its legitimacy in the information age. Section four addresses some objects of implementation, like IT-inspired redesign, HRM and the phenomenon of Street Level Bureaucrats. Finally, the last section offers some concluding thoughts.
