Footnote

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.
