These essays, written by distinguished colleagues, from different academic and professional backgrounds, give an updated and well informed overview of some of the ground-breaking online research methods, their strengths and shortcomings, examine and discuss important ethical and legal issues, and provide, when appropriate, practical guidance on how to conduct and apply each of these methods. For all these reasons, I trust the book will be useful for students, teachers, researchers and practitioners in the field of urban and planning studies, and in related disciplines.
