I find this book by Bernard Marr a masterpiece for any one interested in the field of intellectual capital. Marr systematically and thoroughly walks the reader through the broad spectrum of constructs that form part of this multi-disciplinary research field (economics, strategy, accounting, human resources, information technology, etc.). The target audience of this book is anybody interested in the field of intellectual capital, from readers relatively novel in the field, to researchers. Marr has done a terrific job in putting together this book with contributions from top experts in intellectual capital, bridging the gap between the academic and the practitioner's worlds. I enjoyed the book in its entirety, but I found the last chapter particularly enlightening, in that Marr offers an interdisciplinary overview of the evolution of intellectual capital. The chapter is the first published document I have come across that attempts to create a holistic understanding of the subject, bringing together the different perspectives. I am hopeful that this book will further enhance awareness across many related disciplines, and therefore open doors for future research cross-fertilization and collaboration. As an executive, I also highly recommend this book to anyone interested in furthering his or her thinking in a field that is critical to every business.
