The book is rich with recommendations and tips, scientific evidence and examples of Web surveys, and challenges facing the future of the science ... Those interested in research on Web surverys will find many useful suggesttions for future research in this book ... The greatest strength of The Science of Web Surverys, however, is its plethora and synthesis of current scientific evidence on chapter topics, many times including the authors' own studies. Almost every practical tip, recommendation, and solution to Web surveys in the book is supported by research evidence.
