In fact, it is so distinctive as to make comparison with other glossaries very difficult. Like Weik (cf. BKCMSTDC.RVW) and Shnier (cf. BKCMPDCT.RVW), a number of the entries are more encyclopedic than simply defining. The subject range is quite broad. Many fields of communications are covered, but there is also ample coverage of the computer domain and of scientific realms touching (sometimes quite tangentially) on communications. The strongest emphasis in this work is the historical background, giving information on a great deal of early development, as well as quick biographies of pioneers in the area. It is difficult to determine an area of professional specialization in this work. Telephony and radio get good overviews, but more in past development. Current technologies are not examined in great depth, although history is. A number of popular historical myths are corrected, although there are some assertions with which I'm not quite comfortable, and for which I would have liked to see specific references. Slang is included. At times this may lead to some dispute over the definitions which are, after all, rather informal. For example, cheapernet is defined as any inexpensive LAN technology, while I always heard it used referring specifically to the thinner (RG-58 and RG-62) version of coaxial cable that became popular for Ethernet (and, for a brief time, ARCnet). (And "spam" makes no mention of Vikings.) I was delighted at the number of entries for Canadian technology and inventors. (Not surprised, of course, but delighted.) The entries for "top level" national Internet domains seem to be a bit of a waste of space, especially since the domains are listed in Appendix D. Not all of the explanations are functionally complete. For example, Daniel Bernoulli is described as having done work with fluid dynamics, and Bernoulli's Theorem mentions the constant sum of the pressure head, velocity head, and height. The Bernoulli box is described as using technology pioneered by Bernoulli, but this material does not explain the use of a high speed air jet which maintains an air gap while keeping it vanishingly small. Since Bernoulli's bio also mentions electronics, some readers could be forgiven for assuming that this was his contribution to the Bernoulli drive, rather than the same principle that keeps planes in the air. I noted a slight, but general, weakness in regard to the UNIX operating system, and systems derived from it. (UNIX has, of course, a great many connections to modern networking, and particularly the Internet, so there are a number of related entries.) Explanations are not necessarily incorrect, but are often clumsy, in a manner very similar to those given by people not quite familiar with the technology. Virus is not defined: it isn't even included. The cookie monster program is characterized as a virus, when the program described was a completely non-reproducing prank which had to be initiated by a colleague (generally while you left the terminal unattended but logged on). (There was a Spanish "cookie" [galleta] virus, but it ran on MS-DOS rather than VMS.) A trojan horse is described only as a password collector. Worm is defined only as the Internet Worm, which is defined as a virus, and refers one to virus. Which is not defined ... Errors, additions, and corrections will be noted at http://www.abiogenesis.com/telecomdict/Docs/notes.html. CRC Press is not exactly common on bookstore shelves (and this cover isn't snappy), which is a great pity, because this book is written at the right level, and with the right scope, for the home market. Get this as a present for your favorite techie, and I can pretty much guarantee that they will not be disappointed. Old ham operators and telephone workers will be ecstatic. Professionals may or may not find it useful in their work, but they will most certainly find it fascinating reading, with a great many historical points and canned biographies. Despite the gaps, I hope a bunch of you buy it, because I am dying to see what the author can do with good sales and some feedback on topics to include. copyright Robert M.
