‘Public affairs, and particularly lobbying, is still surrounded by images of mystery. This is harmful for the profession, and it is the profession itself that can improve reputation and elevate the field to more public recognition. With a more open approach to ways of influencing, goals and ethical principles and norms, public affairs can become a more socially responsible field of practice. One way to stimulate this is by bringing together scholars and practitioners to reflect on the ways and means of influencing public policy and making systematic learning more rewarding. This new Handbook written by an impressive group of scholars and practitioners addresses key topics and adds much to learning, both by students and practitioners in the field. Rather than a “how to do”-book, it is a book about ‘how to think and look’ and presents critical yet constructive perspectives on public affairs. It helps unveiling the mystery of lobbying.’
