Verfassungsblog, Germany’s blog “on matters constitutional” started five years ago. Initially Maximilian Steinbeis’ solo effort, it has evolved into a joint venture with Wissenschaftskolleg zu Berlin and Humboldt Universität Berlin. In addition, more and more content is published in German and English, making Verfassungsblog a unique resource for current debates on constitutional matters in Germany and the European Union, such as the TTIP debate. All the best, Verfassungsblog!
