This book examines user perceptions of European Union institutions and compares them to perceptions communicators within these institutions have of their users. Analysing the images both sides have through their interaction on the EUROPA website (www.europa.eu) helps to to show where communicator intentions and user perceptions do or do not overlap.The timeliness of this issue could not be more striking than in the current internal and external debates surrounding the EU (e.g., the "No" votes on the common constitution). With this in mind, every possible way of interaction should be reconsidered, in order for citizens to get more involved and feel more connected. Next to mass media, the Internet plays an increasingly important role in people's lives. Even though the Internet may not currently be a dominant source of information about the RU relative to other mass media outlets , it continues to increase in importance as part of most people's everyday life, in particular for the younger generation who turn to it for information. The main focus of this book is on the integration of both the user and the communicator perspectives. By looking at user needs in comparison to the production processes that determine the information structure of a Web site, the usability of a Web site is defined. The user experience online in turn determines the users' perceptions of the institutions and their attitudes towards the European Union.
