- Abstract
- The book's central thesis is that information literacy, information architecture, and usability are all critical components of this new world order. Hand in hand with that is the contention that only by planning and designing the best possible software, devices, and Internet, will we be able to maintain this connectivity in the future. Morville's book is highlighted with full color illustrations and rich examples that bring his prose to life. Ambient Findability doesn't preach or pretend to know all the answers. Instead, it presents research, stories, and examples in support of its novel ideas. Are w truly at a critical point in our evolution where the quality of our digital networks will dictate how we behave as a species? Is findability indeed the primary key to a successful global marketplace in the 21st century and beyond. Peter Morville takes you on a thought-provoking tour of these memes and more -- ideas that will not only fascinate but will stir your creativity in practical ways that you can apply to your work immediately.

- Rez. in: nfd - Information Wissenschaft und Praxis 57(2006) H.3, S.177-178 (D. Lewandowski): "Wohl unbestritten ist, dass die Suche in Informationsbeständen eine immer größere Bedeutung erhält. Wir suchen nicht nur noch explizit, indem wir ein Informationssystem anwählen und dort eine Suche absetzen, sondern verwenden Suchfunktionen innerhalb von Programmen, auf Websites, innerhalb des Betriebssystems unseres Computers oder sogar ziemlich unbewusst, indem wir Informationen maßgeschneidert aufgrund einer einmal hinterlegten Suche oder eines automatisch erstellten Suchprofils erhalten. Man kann also in der Tat davon sprechen, dass wir von der Suche umgeben werden. Das ist mit dem Konzept der "Ambient Findability" gemeint. Angelehnt ist diese Bezeichnung an den Begriff der "Ambient Music" (in den 70er Jahren durch Brian Eno geprägt), die den Hörer umgibt und von ihm oft gar nicht aktiv wahrgenommen wird. Um eine Vorstellung von dieser Musik zu bekommen, eignet sich vielleicht am besten der Titel einer Platte eben von Brian Eno: "Music for Airports". Peter Morville, bekannt als Co-Autor des empfehlenswerten Buchs "Information Architecture for the World Wide Web"', hat sich nun mit der Veränderung der Suche auseinandergesetzt. Sein Buch bedient sich in ganz unterschiedlichen Disziplinen, um die Prozesse des Suchens, Stöberns und Findens aufzuzeigen. So finden sich Betrachtungen über die Orientierung des Menschen in unbekannten Umgebungen, über die Interaktion mit Informationssystemen, über das soziale Verhalten der Web-Nutzer (Stichworte: Content-Tagging, Folksonomies, Social Networking) und über technische Veränderungen durch die Verfügbarkeit von Informationssystemen in allen Lebenskontexten, vor allem auch über mobile Endgeräte. Das Buch ist in sieben Kapitel gegliedert. Das erste, "Lost and Found" betitelt, bietet auf wenigen Seiten die Definitionen der zentralen Begriffe ambient und findability, erläutert kurz das Konzept der Information Literacy und zeigt, dass die bessere Auffindbarkeit von Informationen nicht nur ein schöner Zusatznutzen ist, sondern sich für Unternehmen deutlich auszahlt.

- Abstract
- The task facing the designers of information retrieval (IR) systems can be stated very simply: to produce the right kind of system with the right components at the right price. In practice, however, this task is greatly hindered by a lack of understanding and communication between the different groups of specialists working on different parts of the system - a problem exacerbated by the fact that each group uses a different jargon, so preventing the exchange of ideas and expertise. There is thus a need for a comprehensive, unified overview of practical computer-based retrieval, and this book provides one. It describes the various parts and their alternative forms, the relationships between them and how these affect the working of the system as a whole. Topics covered include: user, software, knowledge representation, expert systems, database management systems, hardware, user interfaces.

- Rez. in: JASIST 54(2003) no.12, S.1166-1167 (Brenda Chawner): "Kochtanek and Matthews have written a welcome addition to the small set of introductory texts an applications of information technology to library and information Services. The book has fourteen chapters grouped into four sections: "The Broader Context," "The Technologies," "Management Issues," and "Future Considerations." Two chapters provide the broad content, with the first giving a historical overview of the development and adoption of "library information systems." Kochtanek and Matthews define this as "a wide array of solutions that previously might have been considered separate industries with distinctly different marketplaces" (p. 3), referring specifically to integrated library systems (ILS, and offen called library management systems in this part of the world), and online databases, plus the more recent developments of Web-based resources, digital libraries, ebooks, and ejournals. They characterize technology adoption patterns in libraries as ranging from "bleeding edge" to "leading edge" to "in the wedge" to "trailing edge"-this is a catchy restatement of adopter categories from Rogers' diffusion of innovation theory, where they are more conventionally known as "early adopters," "early majority," "late majority," and "laggards." This chapter concludes with a look at more general technology trends that have affected library applications, including developments in hardware (moving from mainframes to minicomputers to personal Computers), changes in software development (from in-house to packages), and developments in communications technology (from dedicated host Computers to more open networks to the current distributed environment found with the Internet). This is followed by a chapter describing the ILS and online database industries in some detail. "The Technologies" begins with a chapter an the structure and functionality of integrated library systems, which also includes a brief discussion of precision versus recall, managing access to internal documents, indexing and searching, and catalogue maintenance. This is followed by a chapter an open systems, which concludes with a useful list of questions to consider to determine an organization's readiness to adopt open source solutions. As one world expect, this section also includes a detailed chapter an telecommunications and networking, which includes types of networks, transmission media, network topologies, switching techniques (ranging from dial up and leased lines to ISDN/DSL, frame relay, and ATM). It concludes with a chapter an the role and importance of standards, which covers the need for standards and standards organizations, and gives examples of different types of standards, such as MARC, Dublin Core, Z39.50, and markup standards such as SGML, HTML, and XML. Unicode is also covered but only briefly. This section world be strengthened by a chapter an hardware concepts-the authors assume that their reader is already familiar with these, which may not be true in all cases (for example, the phrase "client-Server" is first used an page 11, but only given a brief definition in the glossary). Burke's Library Technology Companion: A Basic Guide for Library Staff (New York: Neal-Schuman, 2001) might be useful to fill this gap at an introductory level, and Saffady's Introduction to Automation for Librarians, 4th ed. (Chicago: American Library Association, 1999) world be better for those interested in more detail. The final two sections, however, are the book's real strength, with a strong focus an management issues, and this content distinguishes it from other books an this topic such as Ferguson and Hebels Computers for Librarians: an Introduction to Systems and Applications (Waggawagga, NSW: Centre for Information Studies, Charles Sturt University, 1998). ...
