This book examines the issue of free access to information as part of the openness and transparency principles. The free access to public information has become one of the most hotly contested aspects of contemporary government and public administration. Many countries in Europe have well-established Freedom of Information laws (FOIAs), while others have adopted them more recently. The problems that occur in the implementation of FOIAs are different due to the legal and institutional context; nevertheless, patterns of best practices and malfunctioning are comparable. The book analyses in comparative and empirical perspective the respective main challenges. Whilst the existing literature focusses on the legal provisions, this book offers practical insights through 13 national profiles and the EU level, on how effective the legal provisions of FOIAs really prove to be.
