Review of "The Email Frontier" by blum & litwack. Most books on a technology simply cover the technical details. Few try to cover an enitre "industry" roaming the full terrain of technology and business. This is one of those efforts, looking at an industry which shows the peculiar characteristics of being twenty years old, yet oddly nascent in much of its service and product offerings. Unless the book were entirely incompetent, I would automatically recommend it by virtue of its scope and the importance of the industry. In fact, the book is quite competent. Truth in packaging: I was a compensated pre-publication reviewer for this book, with respect to its discussion of Internet email and the Internet standards process. I'd like to claim that this makes the book's coverage of those topics stellar but it isn't quite that good. The authors have extensive background in electronic mail consulting. Such a business is dominated by work with proprietary products and public messaging services, with interconnection dominated by X.400 technology. Until recently, there was essentially no "Internet email" industry. Therefore like most workers in the commercial sector of email, the authors had limited contact with the Internet. The book reflects that limitation, though not egregiously. In fact, the authors do an excellent job of attempting to overcome what one might call bad training. They do this by focussing on pragmatics. The usual failing of email discussions is the mystical hand-wave that promises the ultimate success of X.400, ignoring its astonishingly slow growth and the real and massive traffic dominance by Internet email. After more than 10 years, one must wonder at the style of thinking that allows one to ignore the power of a huge installed base, such as the Internet. E-Mail Frontier is broad, thorough and well-organized. It discusses business, marketing, product, service, technology, and standards issues, attempting to provide a pragmatic view of the entire industry. It largely succeeds. Don't rely on it as a definitive source for particular details. Instead, use it as a comprehensive introduction and a broad analysis of the messaging industry. If you are a communications manager, are involved in product marketing, or are otherwise concerned with global, distributed applications services, you should read Email Frontier.
