An der faktisch gegebenen Positionierung als Textbuch für Information Retrieval, einigen Themenfeldern der Informationsvermittlung und des Bibliothekswesens ist zwar grundsätzlich nichts auszusetzen. Leider führt aber die Vielzahl der behandelten Themen dazu, dass trotz des Umfangs von gut 500 Seiten manche für das IR wichtige Themen nur sehr knapp abgehandelt wurden. Diese thematische Überbreite macht den Band leider als generelle Einführung für Leser ohne fachlichen Hintergrund in Informations- oder Bibliothekswissenschaft ungeeignet, denn für diese ist ein großer Teil des Buches nicht ausreichend verständlich.

    Rez. in: JASIST 55(2004) no.2, S.178-179 (M.-Y. Kan): "In their latest book, Chowdhury and Chowdhury have written an introductory text an digital libraries, primarily targeting "students researching digital libraries as part of information and library science, as well as computer science, courses" (p. xiv). It is an ambitious work that surveys many of the broad topics in digital libraries (DL) while highlighting completed and ongoing DL research in many parts of the world. With the revamping of Library and Information Science (LIS) Curriculums to focus an information technology, many LIS schools are now teaching DL topics either as an independent course or as part of an existing one. Instructors of these courses have in many cases used supplementary texts and compeed readers from journals and conference materials, possibly because they feel that a suitable textbook has yet to be written. A solid, principal textbook for digital libraries is sorely needed to provide a critical, evaluative synthesis of DL literature. It is with this in mind that I believe Introduction to Digital Libraries was written. An introductory text an any Cross-disciplinary topic is bound to have conflicting limitations and expectations from its adherents who come from different backgrounds. This is the rase in the development of DL Curriculum, in which both LIS and computer science schools are actively involved. Compiling a useful secondary source in such Cross-disciplinary areas is challenging; it requires that jargon from each contributing field be carefully explained and respected, while providing thought-provoking material to broaden student perspectives. In my view, the book's breadth certainly encompasses the whole of what an introduction to DL needs, but it is hampered by a lack of focus from catering to such disparate needs. For example, LIS students will need to know which key aspects differentiate digital library metadata from traditional metadata while computer science students will need to learn the basics of vector spare and probabilistic information retrieval. However, the text does not give enough detail an either subject and thus even introductory students will need to go beyond the book and consult primary sources. In this respect, the book's 307 pages of content are too short to do justice to such a broad field of study.
    Chapter 2 examines the variety and breadth of DL implementations and collections through a well-balanced selection of 20 DLs. The authors make a useful classification of the various types of DLs into seven categories and give a brief synopsis of two or three examples from each category. These categories include historical, national, and university DLs, as well as DLs for special materials and research. Chapter 3 examines research efforts in digital libraries, concentrating an the three eLib initiatives in the UK and the two Digital Libraries Initiatives in the United States. The chapter also offers some details an joint research between the UK and the United States (the NSF/JISC jointly funded programs), Europe, Canada, Australia, and New Zealand. While both of these chapters do an admirable job of surveying the DL landscape, the breadth and variety of materials need to be encapsulated in a coherent summary that illustrates the commonality of their approaches and their key differences that have been driven by aspects of their collections and audience. Unfortunately, this summary aspect is lacking here and elsewhere in the book. Chapter 2 does an admirable job of DL selection that showcases the variety of existing DLs, but 1 feel that Chapter 3's selection of research projects could be improved. The chapter's emphasis is clearly an UK-based research, devoting nine pages to it compared to six for EU-funded projects. While this emphasis could be favorable for UK courses, it hampers the chances of the text's adoption in other courses internationally. Chapter 4 begins the core part of the book by examining the DL from a design perspective. As a well-designed DL encompasses various practical and theoretical considerations, the chapter introduces much of the concepts that are elaborated an in later chapters. The Kahn/Wilensky and Lagoze/Fielding architectures are summarized in bullet points, and specific aspects of these frameworks are elaborated on. These include the choice between a federated or centralized search architecture (referencing Virginia Tech's NDLTD and Waikato's Greenstone) and level of interoperability (discussing UNIMARC and metadata harvesting). Special attention is paid to hybrid library design, with references to UK projects. A useful summary of recommended standards for DL design concludes the chapter.
