Many libraries are creating raster images of paper maps and making them available over the Internet. This presentation provides an overview of imaging technology for map librarians and administrators considering such projects. References in footnotes and the bibliography enable those interested to explore technical questions in depth. There are…

There are now major efforts being undertaken throughout the world to digitize and preserve significant materials. Digital acquisition, which is the conversion of physical materials into a digital format, allows the possibility of efficient dissemination, and serves as a means of preservation. This paper presents research focused on developing new…

Discusses 3 D imaging as it relates to digital representations in virtual library collections. Highlights include X-ray computed tomography (X-ray CT); the National Science Foundation (NSF) Digital Library Initiatives; output peripherals; image retrieval systems, including metadata; and applications of 3 D imaging for libraries and museums. (LRW)

Describes a seven-year experience with developing the Tufts Health Sciences Database, a database-driven information management system that combines the strengths of a digital library, content delivery tools, and curriculum management. Identifies major effects on teaching and learning. Also addresses issues of faculty development, copyright and…

Discussion of weighted index terms in information retrieval focuses on a method for adjusting index weights by processing text in digital libraries that has been highlighted by users. Considers weights in query processing; feedback sources; active reading while accessing digital documents; collaborative information retrieval; and improving index…

Explores factors in the history of the Open Archives Initiative (OAI) that have contributed to the positive response of the digital library and information community toward version 2 of the OAI Protocol for Metadata Harvesting. Factors include focus on a defined problem statement, an operational model in which strong leadership is balanced with…

Describes the use of the Open Archives Initiative (OAI) Protocol for Metadata Harvesting in the National Science Foundation's (NSF) National Science Digital Library (NSDL). Describes the implementation experience and early practical tests. The overall conclusion is optimism that the OAI will be a successful part of the NSDL. (Author/AEF)

Highlights the importance of conceptual and theoretical work in designing information retrieval systems. Examines two epistemological positions leading to different solutions in digital library design: the information transfer perspective and the social constructionist knowledge production perspective. Suggests that noun-based approaches can be…

Discusses the development of digital collections and digital libraries. Topics include digitization of cultural heritage information; broadband issues; lack of compelling content; training issues; types of materials being digitized; sustainability; digital preservation; infrastructure; digital images; data mining; and future possibilities for…

Discusses digital collections and digital libraries. Topics include broadband availability; digital rights protection; content, both non-profit and commercial; digitization of cultural content; sustainability; metadata harvesting protocol; infrastructure; authorship; linking multiple resources; data mining; digitization of reference works;…

Presents a conceptual framework for digital library development and discusses how to move from isolated digital collections to interoperable digital libraries. Topics include a history of digital libraries; user-centered architecture; stages of technological development; standards, including metadata; and best practices. (Author/LRW)

Takes a fanciful journey into the digital library imagined by Jorge Luis Borges, and uses it as a metaphor to examine what sort of library the World Wide Web is. Examines how digital libraries are growing and what they mean for literacy education. Includes a description of a particular Web page, and a glossary. (SR)

Explains how to build World Wide Web home pages using frames-based HTML so that librarians can manage Web-based information and improve their home pages. Provides descriptions and 15 examples for writing frames-HTML code, including advanced concepts and additional techniques for home-page design. (Author/LRW)

Discusses problems in creating indices and thesauri for digital libraries of geo-spatial multimedia content and proposes a scalable method to automatically generate visual thesauri of large collections of geo-spatial media using fuzzy, unsupervised machine-learning techniques. Uses satellite photographs as examples and discusses texture-based…

Discusses the design of the National Taiwan University Digital Library and Museum that addresses both content and knowledge management. Describes a two-tier repository architecture that facilitates content management, includes an object-oriented model to facilitate the management of temporal information, and eliminates the need to manually…
