    Abstract
    The National Science Foundation's (NSF) National Science, Mathematics, Engineering, and Technology Education Digital Library (NSDL) program seeks to create, develop, and sustain a national digital library supporting science, mathematics, engineering, and technology (SMET) education at all levels -- preK-12, undergraduate, graduate, and life-long learning. The resulting virtual institution is expected to catalyze and support continual improvements in the quality of science, mathematics, engineering, and technology (SMET) education in both formal and informal settings. The vision for this program has been explored through a series of workshops over the past several years and documented in accompanying reports and monographs. (See [1-7, 10, 12, and 13].) These efforts have led to a characterization of the digital library as a learning environments and resources network for science, mathematics, engineering, and technology education, that is: * designed to meet the needs of learners, in both individual and collaborative settings; * constructed to enable dynamic use of a broad array of materials for learning primarily in digital format; and * managed actively to promote reliable anytime, anywhere access to quality collections and services, available both within and without the network. Underlying the NSDL program are several working assumptions. First, while there is currently no lack of "great piles of content" on the Web, there is an urgent need for "piles of great content". The difficulties in discovering and verifying the authority of appropriate Web-based material are certainly well known, yet there are many examples of learning resources of great promise available (particularly those exploiting the power of multiple media), with more added every day. The breadth and interconnectedness of the Web are simultaneously a great strength and shortcoming. Second, the "unit" or granularity of educational content can and will shrink, affording the opportunity for users to become creators and vice versa, as learning objects are reused, repackaged, and repurposed. To be sure, this scenario cannot take place without serious attention to intellectual property and digital rights management concerns. But new models and technologies are being explored (see a number of recent articles in the January issue of D-Lib Magazine). Third, there is a need for an "organizational infrastructure" that facilitates connections between distributed users and distributed content, as alluded to in the third bullet above. Finally, while much of the ongoing use of the library is envisioned to be "free" in the sense of the public good, there is an opportunity and a need to consider multiple alternative models of sustainability, particularly in the area of services offered by the digital library. More details about the NSDL program including information about proposal deadlines and current awards may be found at <http://www.ehr.nsf.gov/ehr/due/programs/nsdl>.

    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). ...

    Rez. in: KO 31(2004) no.2, S.117-118 (D. Campbell): "This excellent volume offers 22 papers delivered at an IFLA Satellite meeting in Dublin Ohio in 2001. The conference gathered together information and computer scientists to discuss an important and difficult question: in what specific ways can the accumulated skills, theories and traditions of librarianship be mobilized to face the challenges of providing subject access to information in present and future networked information environments? The papers which grapple with this question are organized in a surprisingly deft and coherent way. Many conferences and proceedings have unhappy sessions that contain a hodge-podge of papers that didn't quite fit any other categories. As befits a good classificationist, editor I.C. McIlwaine has kept this problem to a minimum. The papers are organized into eight sessions, which split into two broad categories. The first five sessions deal with subject domains, and the last three deal with subject access tools. The five sessions and thirteen papers that discuss access in different domains appear in order of in creasing intension. The first papers deal with access in multilingual environments, followed by papers an access across multiple vocabularies and across sectors, ending up with studies of domain-specific retrieval (primarily education). Some of the papers offer predictably strong work by scholars engaged in ongoing, long-term research. Gerard Riesthuis offers a clear analysis of the complexities of negotiating non-identical thesauri, particularly in cases where hierarchical structure varies across different languages. Hope Olson and Dennis Ward use Olson's familiar and welcome method of using provocative and unconventional theory to generate meliorative approaches to blas in general subject access schemes. Many papers, an the other hand, deal with specific ongoing projects: Renardus, The High Level Thesaurus Project, The Colorado Digitization Project and The Iter Bibliography for medieval and Renaissance material. Most of these papers display a similar structure: an explanation of the theory and purpose of the project, an account of problems encountered in the implementation, and a discussion of the results, both promising and disappointing, thus far. Of these papers, the account of the Multilanguage Access to Subjects Project in Europe (MACS) deserves special mention. In describing how the project is founded an the principle of the equality of languages, with each subject heading language maintained in its own database, and with no single language used as a pivot for the others, Elisabeth Freyre and Max Naudi offer a particularly vivid example of the way the ethics of librarianship translate into pragmatic contexts and concrete procedures. The three sessions and nine papers devoted to subject access tools split into two kinds: papers that discuss the use of theory and research to generate new tools for a networked environment, and those that discuss the transformation of traditional subject access tools in this environment. In the new tool development area, Mary Burke provides a promising example of the bidirectional approach that is so often necessary: in her case study of user-driven classification of photographs, she user personal construct theory to clarify the practice of classification, while at the same time using practice to test the theory. Carol Bean and Rebecca Green offer an intriguing combination of librarianship and computer science, importing frame representation technique from artificial intelligence to standardize syntagmatic relationships to enhance recall and precision.
