    Abstract
    The National Science Foundation's (NSF) National Science, Technology, Engineering, and Mathematics Education Digital Library (NSDL) program comprises a set of projects engaged in a collective effort to build a national digital library of high quality science, technology, engineering, and mathematics (STEM) educational materials for students and teachers at all levels, in both formal and informal settings. By providing broad access to a rich, reliable, and authoritative collection of interactive learning and teaching resources and associated services in a digital environment, the NSDL will encourage and sustain continual improvements in the quality of STEM education for all students, and serve as a resource for lifelong learning. Though the program is relatively new, its vision and operational framework have been developed over a number of years through various workshops and planning meetings. The NSDL program held its first formal funding cycle during fiscal year 2000 (FY00), accepting proposals in four tracks: Core Integration System, Collections, Services, and Targeted Research. Twenty-nine awards were made across these tracks in September 2000. Brief descriptions of each FY00 project appeared in an October 2000 D-Lib Magazine article; full abstracts are available from the Awards Section at <http://www.ehr.nsf.gov/ehr/due/programs/nsdl/>. In FY01 the program received one hundred-nine proposals across its four tracks with the number of proposals in the collections, services, and targeted research tracks increasing to one hundred-one from the eighty received in FY00. In September 2001 grants were awarded to support 35 new projects: 1 project in the core integration track, 18 projects in the collections track, 13 in the services track, and 3 in targeted research. Two NSF directorates, the Directorate for Geosciences (GEO) and the Directorate for Mathematical and Physical Sciences (MPS) are both providing significant co-funding on several projects, illustrating the NSDL program's facilitation of the integration of research and education, an important strategic objective of the NSF. Thus far across both fiscal years of the program fifteen projects have enjoyed this joint support. Following is a list of the FY01 awards indicating the official NSF award number (each beginning with DUE), the project title, the grantee institution, and the name of the Principal Investigator (PI). A condensed description of the project is also included. Full abstracts are available from the Awards Section at the NSDL program site at <http://www.ehr.nsf.gov/ehr/due/programs/nsdl/>. (Grants with shared titles are formal collaborations and are grouped together.) The projects are displayed by track and are listed by award number. In addition, six of these projects have explicit relevance and application to K-12 education. Six others clearly have potential for application to the K-12 arena. The NSDL program will have another funding cycle in fiscal year 2002 with the next program solicitation expected to be available in January 2002, and an anticipated deadline for proposals in mid-April 2002.

    Abstract
    This article describes an approach for linking geographically distributed collections of metadata so that they are searchable as a single collection. We describe the infrastructure, which uses standard Internet protocols such as the Lightweight Directory Access Protocol (LDAP) and the Common Indexing Protocol (CIP), to distribute queries, return results, and exchange index information. We discuss the advantages of using linked collections of authoritative metadata as an alternative to using a keyword indexing search-engine for resource discovery. We examine other architectures that use metadata for resource discovery, such as Dienst/NCSTRL, the AHDS HTTP/Z39.50 Gateway, and the ROADS initiative. Finally, we discuss research issues and future directions of the project. The Internet Scout Project, which is funded by the National Science Foundation and is located in the Computer Sciences Department at the University of Wisconsin-Madison, is charged with assisting the higher education community in resource discovery on the Internet. To that end, the Scout Report and subsequent subject-specific Scout Reports were developed to guide the U.S. higher education community to research-quality resources. The Scout Report Signpost utilizes the content from the Scout Reports as the basis of a metadata collection. Signpost consists of more than 2000 cataloged Internet sites using established standards such as Library of Congress subject headings and abbreviated call letters, and emerging standards such as the Dublin Core (DC). This searchable and browseable collection is free and freely accessible, as are all of the Internet Scout Project's services.

    Abstract
    In fall 2004, the National Science Foundation's (NSF) National Science, Technology, Engineering, and Mathematics Education Digital Library (NSDL) program made new grants in three tracks: Pathways, Services, and Targeted Research. Together with projects started in fiscal years (FY) 2000-03 these new grants continue the development of a national digital library of high quality educational resources to support learning at all levels in science, technology, engineering, and mathematics (STEM). By enabling broad access to reliable and authoritative learning and teaching materials and associated services in a digital environment, the National Science Digital Library expects to promote continual improvements in the quality of formal STEM education, and also to serve as a resource for informal and lifelong learning. Proposals for the FY05 funding cycle are due April 11, 2005, and the full solicitation is available at <http://www.nsf.gov/publications/pub_summ.jsp?ods_key=nsf05545>. Two NSF directorates, the Directorate for Geosciences (GEO) and the Directorate for Mathematical and Physical Sciences (MPS) have both provided significant co-funding for over twenty projects in the first four years of the program, illustrating the NSDL program's facilitation of the integration of research and education, an important strategic objective of the NSF. In FY2004, the NSDL program introduced a new Pathways track, replacing the earlier Collections track. The Services track strongly encouraged two particular types of projects: (1) selection services and (2) usage development workshops. * Pathways projects provide stewardship for educational content and services needed by a broad community of learners; * Selection services projects identify and increase the high-quality STEM educational content known to NSDL; and * Usage development workshops engage new communities of learners in the use of NSDL and its resources.

    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.
