Anyone with an interest in the way information systems and communication methods have developed - and continue to develop - will find significant value in this book.
Whether that interest is academic or personal, from a historical or scientific background, the clarity of the writing (and lack of jargonese) allows the reader to absorb many useful concepts without draining the whole of the brain's attention (i.e. leaving one with enough thought process remaining to simultaneously consider the implications for your own area of study).
As a scientist with a very different angle on signals and information, it seems bizarre to me that the field of information history should have only emerged in the last 20 years, and that this would be the first book dedicated to it - let alone that the author should need to argue in academic circles for the validity of the field (which I understand has been the case).
It appears all the more relevant in what continues to be a rapid acceleration of the "information age" in the last 5-10 years, as global communications expands such that we have access to information on anything available to us anywhere.
Who among us predicted the popularity of text messaging, or the sudden trend surges of different Internet fora, particularly MySpace and Facebook? And what will be the next? Will it all be based on media hype, a brand new technology, or will it fall down to the same subtle information needs for human communication which have been evolving for centuries?
Overall, a thought provoking book, with sections dedicated to different angles and perspectives, such as the "origins of the information society", "how do we avoid imposing order understandings on the past?", and looking ahead to "the next 10 years..." Highly recommended.
