This open access book explores how digital tools and social media technologies can contribute to better participation and involvement of EU citizens in European politics. By analyzing selected representative e-participation projects at the local, national and European governmental levels, it identifies the preconditions, best practices and shortcomings of e-participation practices in connection with EU decision-making procedures and institutions. The book features case studies on parliamentary monitoring, e-voting practices, and e-publics, and offers recommendations for improving the integration of e-democracy in European politics and governance. Accordingly, it will appeal to scholars as well as practitioners interested in identifying suitable e-participation tools for European institutions and thus helps to reduce the EU's current democratic deficit. This book is a continuation of the book "Electronic Democracy in Europe" published by Springer.
