Das Buch besteht aus zwei Teilen: Section 1 - Accessibility and Why It Matters Section 2 - Strategies and Techniques for Maximum Accessibility Im ersten Teil geben die Autoren eine knappe Einführung, in der sie erläutern, was Accessibility bedeutet, und stellen die gesetzlichen Grundlagen in den USA vor. Daneben werfen sie aber auch einen kurzen Blick auf die Situation in Kanada, Australien, der Europäischen Union (EU) und Großbritannien (das interessanterweise nicht zur EU gezählt, sondern gesondert behandelt wird). Der Schwerpunkt USA und die dortige Gesetzeslage ist auch für Leser aus dem deutschsprachigen Raum durchaus interessant dargestellt, erlaubt er doch den Vergleich mit der gesetzlichen Lage in der EU, die durchaus nicht einheitlich ist-in einigen Staaten gelten die Vorschriften der Barrierefreiheit auch für kommerzielle Web-Angebote, z. B. in Großbritannien. In den weiteren Kapiteln wird ein breites Spektrum abgedeckt: Es werden verschiedene Initiatitiven zur Barrierefreiheit in den USA vorgestellt ebenso wie ein business case, der zeigt wie der return an Investment für Barrierefreiheit in einem konkreten Fall aussehen kann. Slatin und Rush gehen davon aus, dass Barrierefreiheit für jedes Unternehmen aus Geschäftsinteresse sinnvoll ist, weil immer mehr Menschen immer älter werden und damit die Wahrscheinlichkeit von körperlichen Beeinträchtigungen zunimmt. Dann liefern sie eine Reihe von Argumenten, warum sich Barrierefreiheit für Unternehmen rechnet. Im Anschluss geben sie einen Überblick, wie man WebSites auf Barrierefreiheit testet, wobei sie betonen, dass automatisierte Prüfwerkzeuge nur in Kombination mit einer Evaluation durch Gutachter bzw. UsabilityTests verwendet werden sollten. Allerdings, so räumen Slatin und Rush ein, helfen diese Werkzeuge und Methoden nicht, die absolute Barrierefreiheit für jeden einzelnen Benutzer oder unter allen Umständen zu erreichen. Anhand von Beispielen zeigen Slatin und Rush, dass Textversionen der Inhalte keine wirkliche Alternative zu tatsächlich barrierefreien Inhalten sind und wie Alternativen für die barrierefreie Präsentation multimedialer Inhalte zur Verfügung stehen. Im ersten Teil sind verschiedene Kapitel mit Erfahrungsberichte des blinden John Slatin eingebunden, die praxisbezogen und anschaulich zeigen, auf welche Probleme Blinde und Sehbehinderte im Web stoßen, so zum Beispiel - dass es für einen blinden Benutzer in der beschriebenen Version praktisch unmöglich war, bei der beschriebenen Version von Amazon online einzukaufen. - dass sich bei ÖPNV-Web-Angeboten trotz des Einsatzes assistiver Technologien wie beispielsweise eines Bildschirmvorleseprogramms (screen reader) erhebliche Probleme mit Tabellen ergeben, die durch ihre zweidimensionale Struktur zwar für die Wahrnehmung mit dem Auge geeignet sind, nicht aber für die Wahrnehmung mit dem Ohr. Allerdings zeigen Screenshots, dass einige dieser Fahrpläne auch sehende Benutzer vor visuelle und intellektuelle Herausforderungen stellen, weil ihr Informationsdesign schlecht gemacht ist.

Chapter 2 (Technology and People) focuses an several theories of technological acceptance and diffusion. Unfortunately, Bruce's presentation is somewhat confusing as he moves from one theory to next, never quite connecting them into a logical sequence or coherent whole. Two theories are of particular interest to Bruce: the Theory of Diffusion of Innovations and the Theory of Planned Behavior. The Theory of Diffusion of Innovations is an "information-centric view of technology acceptance" in which technology adopters are placed in the information flows of society from which they learn about innovations and "drive innovation adoption decisions" (p. 20). The Theory of Planned Behavior maintains that the "performance of a behavior is a joint function of intentions and perceived behavioral control" (i.e., how muck control a person thinks they have) (pp. 22-23). Bruce combines these two theories to form the basis for the Technology Acceptance Model. This model posits that "an individual's acceptance of information technology is based an beliefs, attitudes, intentions, and behaviors" (p. 24). In all these theories and models echoes a recurring theme: "individual perceptions of the innovation or technology are critical" in terms of both its characteristics and its use (pp. 24-25). From these, in turn, Bruce derives a predictive theory of the role personal perceptions play in technology adoption: Personal Innovativeness of Information Technology Adoption (PIITA). Personal inventiveness is defined as "the willingness of an individual to try out any new information technology" (p. 26). In general, the PIITA theory predicts that information technology will be adopted by individuals that have a greater exposure to mass media, rely less an the evaluation of information technology by others, exhibit a greater ability to cope with uncertainty and take risks, and requires a less positive perception of an information technology prior to its adoption. Chapter 3 (A Focus an Usings) introduces the User-Centered Paradigm (UCP). The UCP is characteristic of the shift of emphasis from technology to users as the driving force behind technology and research agendas for Internet development [for a dissenting view, see Andrew Dillion's (2003) challenge to the utility of user-centerness for design guidance]. It entails the "broad acceptance of the user-oriented perspective across a range of disciplines and professional fields," such as business, education, cognitive engineering, and information science (p. 34).
