This book promises to "take all the hassle out of implementing web menus, in whatever style and technology you wish". It doesn't deliver.
First, I would have expected more about what a "usable Web menu" is. The twelve rules and the brief section on information architecture are pedestrian. The authors recommend usability testing but don't give test results for their own designs. The authors mention "the excellent book 'Web Site Usability'" and then violate its emprically determined recommendations. Rule 2, "Menus must be distinct from content", is a case in point. It contradicts an observation from "Web Site Usability": that "Navigation and content are inseparable".
Second, I would have expected "hooks" between the usability section (design) and the technical section (implementation). The usability section ends on p. 53, and the technical section, which continues for another 150 pages, makes few references to it.
Third, I would have expected suggestions for basic, universally accepted, HTML-only menus. The authors illustrate Rule 12, "Menus must work on multiple browsers", by showing what a fancy graphical menu reduces to in Lynx, the text-only Web browser. Lynx is never heard from again, and every example in the book requires JavaScript, Dynamic HTML, Flash, or, worse yet (for other reasons), server-side scripting.
Fourth, I would have expected information about accessibility. Rule 11, "Menus must be accessible to the handicapped", suffers from outdated diction and a total lack of coverage. The rule is introduced on pp. 31 - 32 but never mentioned again. "Accessiblity" isn't even in the index. Due to heavy use of JavaScript, Dynamic HTML, and Flash, the examples in the book are not accessible. (Incidentally, Web accessibility is often a legal requirement. Any project involving federal money must comply with Section 508 of the Rehabilitation Act.)
Fifth, I would have expected a more professional approach. The tone of the book is informal and sloppy. Sometimes, this covers up the authors' laziness. For example, it's easier to mention an information source (like "Web Site Usability" or the W3C's Web Content Accessibility Guidelines) and call it "excellent" or "eye-opening" than it is to actually read the material, quote from it, and use it.
"Constructing Usable Web Menus" is a diappointment. I'm glad I borrowed it from the library instead of buying it.
