Users experience the usability of a web site before they have committed to using it and before making any purchase decisions. The web is the ultimate environment for empowerment, and he or she who clicks the mouse decides everything. Designing Web Usability is the definitive guide to usability from Jakob Nielsen, the world's leading authority. Over 250,000 Internet professionals around the world have turned to this landmark book, in which Nielsen shares the full weight of his wisdom and experience. From content and page design to designing for ease of navigation and users with disabilities, he delivers complete direction on how to connect with any web user, in any situation. Nielsen has arrived at a series of principles that work in support of his findings: 1. That web users want to find what they're after quickly; 2. If they don't know what they're after, they nevertheless want to browse quickly and access information they come across in a logical manner. This book is a must-have for anyone who thinks seriously about the web.

This guide segments discussions of Web usability into page, content, site, and intranet design. This breakdown skillfully isolates for the reader many subtly different challenges that are often mixed together in other discussions. For example, Nielsen addresses the requirements of viewing pages on varying monitor sizes separately from writing concise text for "scanability." Along the way, the author pulls no punches with his opinions, using phrases like "frames: just say no" to immediately make his feelings known. Fortunately, his advise is some of the best you'll find.

One of the unique aspects of this title is the use of actual statistics to buttress the author's opinions on various techniques and technologies. He includes survey results on sizes of screens, types of queries submitted to search portals, response times by connection type and more. This book is intended as the first of two volumes--focusing on the "what." The author promises a follow-up title that will show the "hows" and, based on this installation, we can't wait. --Stephen W.
