1. in wörtlicher Bedeutung heißt Information also das Versehen von etwas in einer Form, Gestaltgebung 2. in übertragenem Sinne heißt Information genau das gleiche wie unser Wort Bildung welches gleichfalls übertragen gebraucht wird... informatio als Bildung differenziert sich nun wieder in zwei Unterbedeutungen: a) Bildung durch Unterrichtung aa) informatio als Vorgang und ab) informatio als Ergebnis Zur Problematik zwischen Information und Wissen führt er auch die US-Zukunftsforscher Matthias Horx und den alten weisen Josef Weizenbaum an. Dessen scharfe und pointierte Kritik an der Internet-Euphorie liest man heute noch mit Vergnügen. Damit wird einer allzu simplen nationalen Zuweisungen von Vorlieben für Informationswirtschaft als "typisch amerikanisch" und allen kritiklosen Adepten einer Computergläubigkeit eine Absage erteilt. (S.41/42). Es ist erstaunlich, dass es Ratzek gelingt, den thematischen Umfang des Buches in nur drei großen Abschnitten unterzubringen, die er Teil A: Grundlagen, Teil B: Techniksynopse und Teil C: Visionen nennt. Die unter diesen Teilen aufgeführten Kapitel folgen ohne Abweichungen den vorgegebenen Themen. Die knapp gehaltenen Zusammenfassungen werden von sehr klaren und anschaulichen Grafiken unterstrichen. Um diese sehr stringente Einteilung nicht zu unterbrechen, gibt es bisweilen Exkurse, die kleine historische oder auch philosophische Ausflüge erlauben. Dies ist notwendig, denn Ratzek versucht nicht nur die von ihm vorgegebene Problematik immer wieder aufzunehmen, sondern er will diese auch auf allen Feldern der Informationstechnologie exemplifizieren. Dazu gehören nicht nur die Informationstechnologie und ihre diversen Apparate sowie die Netzwerke wie Telefon und Fernsehen, die letztendlich zu dem immer wieder durchscheinenden Credo des Autors führen: "...weil es eine Pflicht für Informationswissenschaftler ist, zu denen der Autor gehört, diesen Unterschied zu erkennen und darauf hinzuweisen, dass nicht die Informatisierung der Gesellschaft und Wirtschaft das Ziel sein kann, sondern der sinnvolle Umgang mit Information und Wissen." (S.177)

Chapter 12 on "Web Presence" is a useful discussion of what it means to have a Web site that is indexed by a spider from a major Web search engine. Chapter 13 on "Mobile Computing" is very well done and gives the reader a solid basis of what is involved with mobile computing without overwhelming them with technical details. Chapter 14 discusses the difference between pull technologies and push technologies using the Web that is understandable to almost anyone who has ever used the Web. Chapters 15, 16, and 17 are for the technically stout at heart; they cover "Dynamic Web Pages," " Embedded Scripts," and "Peer-to-Peer Computing." These three chapters will tend to dampen the spirits of anyone who does not come from a technical background. Chapter 18 on "Symbolic Services-Information Providers" and chapter 19 on "OnLine Symbolic Services-Case Studies" are ideal for class discussion and students assignments as is chapter 20, "Online Retail Shopping-Physical Items." Chapter 21 presents a number of case studies on the "Technical Constraints" discussed in chapter 3 and chapter 22 presents case studies on the "Cultural Constraints" discussed in chapter 4. These case studies are not only presented in an interesting manner they focus on situations that most Web users have encountered but never really given much thought to. Chapter 24 "A Better Model?" discusses a combined "formalized/unformalized" model that might make Web applications such as banking and booking travel work better than the current models. This chapter will cause readers to think about the role of formalization and the unformalized processes that are involved in any application. Chapters 24, 25, 26, and 27 which discuss the role of "Data Exchange," "Formalized Data Exchange," "Electronic Data Interchange-EDI," and "XML" in business-to-business applications on the Web may stress the limits of the nontechnically oriented reader even though it is presented in a very understandable manner. Chapters 28, 29, 30, and 31 discuss Web services, the automated value chain, electronic market places, and outsourcing, which are of high interest to business students, businessmen, and designers of Web applications and can be skimmed by others who want to understand ebusiness but are not interested in the details. In Part 5, the chapters 32, 33, and 34 on "Interfacing with the Web of the Future," "A Disruptive Technology," "Virtual Businesses," and "Semantic Web," were, for me, who teaches courses in IT and develops ebusiness applications the most interesting chapters in the book because they provided some useful insights about what is likely to happen in the future. The summary in part 6 of the book is quite well done and I wish I had read it before I started reading the other parts of the book.
