Abstract

The increasing volume of information in the contemporary world entails demand for efficient knowledge management (KM) systems; a logical method of information organization that will allow proper semantic querying to identify things that match meaning in natural language. On this concept, the role of an information manager goes beyond implementing a search and clustering system, to the ability to map and logically present the subject domain and related cross domains. From Knowledge Abstraction to Management answers this need by analysing ontology tools and techniques, helping the reader develop

Rez. in: JASIST. 54(2003) no.9, S.908-909 (L. Ennis): "This is a timely and important addition to the growing body of work an libraries and digital collections. Both Deegan and Tanner bring a wide array of experience and knowledge to the work creating a valuable resource for librarians and digital collection managers. The book is the first in what the authors hope will become a series of volumes covering various issues of digital futures. Digital Futures: Strategies for the Information Age contains nine main chapters divided into sections, an introduction, a conclusion, a bibliography, a glossary, and an index. Each chapter begins with a quote or two and an introduction to help set the stage for the rest of the chapter. The first chapter, "Digital Futures in Current Context," outlines the myriad of changes in information technology from the past 50 years and the impact of those changes an libraries, library practices, and publishing. The book is written for people with little or no prior knowledge of information technology, so technologically savvy readers may find the first chapter a little elementary. For instance, the chapter includes a good bit of the history and workings of the Internet and World Wide Web. However, without the chapter included in the text, the work world lack a real starting point for the narrative and possibly alienate readers just starting their voyage into information science. The second chapter, "Why Digitize?" discusses why libraries and librarians should consider digital projects as a means of providing access. While the concentration is an the benefits of digital projects, the authors are also careful to point out various pitfalls and stumbling blocks to creating, managing, and preserving a digital collection. To help demonstrate their point, the authors include examples of a number of active projects covering newspapers, photo collections, books, and periodicals, and provide URLs so readers can visit the projects an their own. This chapter gives the reader a good overview of the various issues surrounding digitization as well as practical examples. While the first two chapters are a good introduction to the subject and examine theoretical issues, the next two chapters begin take an more practical issues. In Chapter Three, "Developing Collections in the Digital World," and four, "The Economic Factors," the authors explore how digital collections work with traditional library collecfions and how collection development for digital resources differs from collection development of non-digital resources. One of the most interesting topics of these chapters covers the issues surrounding serials using JSTOR and Project MUSE as examples. E-books and their impact an libraries is also discussed. The remaining chapters are by far the most timely and important parts of the work. Chapter Five, "Resource Discovery, Description and Use," examines the growing area of metadata and its importance for libraries and librarians. The chapter begins with a look at how the World Wide Web works and the problems with search engines and then evolves into a discussion of what metadata is, the types of metadata, and metadata creation. The authors explain that one of the biggest problems with the World Wide Web is that the construction and description of web pages is imprecise. The solution for bettering retrieval is metadata.
The most common definition for metadata is "data about data." What metadata does is provide schemes for describing, organizing, exchanging, and receiving information over networks. The authors explain how metadata is used to describe resources by tagging item attributes like author, title, creation date, key words, file formats, compression, etc. The most well known scheme is MARC, but other schemes are developing for creating and managing digital collections, such as XML, TEI, EAD, and Dublin Core. The authors also do a good job of describing the difference between metadata and mark-up languages like HTML. The next two chapters discuss developing, designing, and providing access to a digital collection. In Chapter Six, "Developing and Designing Systems for Sharing Digital Resources," the authors examine a number of issues related to designing a shared collection. For instance, one issue the authors examine is interoperability. The authors stress that when designing a digital collection the creators should take care to ensure that their collection is "managed in such a way as to maximize opportunities for exchange and reuse of information, whether internally or externally" (p. 140). As a complement to Chapter Six, Chapter Seven, "Portals and Personalization: Mechanisms for End-user Access," focuses an the other end of the process; how the collection is used once it is made available. The majority of this chapter concentrates an the use of portals or gateways to digital collections. One example the authors use is MyLibrary@NCState, which provides the university community with a flexible user-drive customizable portal that allows user to access remote and local resources. The work logically concludes with a chapter an preservation and a chapter an the evolving role of librarians. Chapter Eight, "Preservation," is a thought-provoking discussion an preserving digital data and digitization as a preservation technique. The authors do a good job of relaying the complexity of preservation issues in a digital world in a single chapter. While the authors do not answer their questions, they definitely provide the reader wich some things to ponder. The final chapter, "Digital Librarians: New Roles for the Information Age," outlines where the authors believe librarianship is headed. Throughout the work they stress the role of the librarian in the digital world, but Chapter Nine really brings the point home. As the authors stress, librarians have always managed information and as experienced leaders in the information field, librarians are uniquely suited to take the digital bull by the horns. Also, the role of the librarian and what librarians can do is growing and evolving. The authors suggest that librarians are likely to move into rotes such as knowledge mediator, information architect, hybrid librarian-who brings resources and technologies together, and knowledge preserver. While these librarians must have the technical skills to cope with new technologies, the authors also state that management skills and subject skills will prove equally important.

Abstract

"How to Build a Digital Library" is the only book that offers all the knowledge and tools needed to construct and maintain a digital library, regardless of the size or purpose. It is the perfectly self-contained resource for individuals, agencies, and institutions wishing to put this powerful tool to work in their burgeoning information treasuries. The second edition reflects new developments in the field as well as in the Greenstone Digital Library open source software. In Part I, the authors have added an entire new chapter on user groups, user support, collaborative browsing, user contributions, and so on. There is also new material on content-based queries, map-based queries, cross-media queries. There is an increased emphasis placed on multimedia by adding a 'digitizing' section to each major media type. A new chapter has also been added on 'internationalization', which will address Unicode standards, multi-language interfaces and collections, and issues with non-European languages (Chinese, Hindi, etc.). Part II, the software tools section, has been completely rewritten to reflect the new developments in Greenstone Digital Library Software, an internationally popular open source software tool with a comprehensive graphical facility for creating and maintaining digital libraries. As with the First Edition, a web site, implemented as a digital library, will accompany the book and provide access to color versions of all figures, two online appendices, a full-text sentence-level index, and an automatically generated glossary of acronyms and their definitions. In addition, demonstration digital library collections will be included to demonstrate particular points in the book. To access the online content please visit our associated website. This title outlines the history of libraries - both traditional and digital - and their impact on present practices and future directions. It is written for both technical and non-technical audiences and covers the entire spectrum of media, including text, images, audio, video, and related XML standards. It is web-enhanced with software documentation, color illustrations, full-text index, source code, and more.

Abstract

Libraries have always been an inspiration for the standards and technologies developed by semantic web activities. However, except for the Dublin Core specification, semantic web and social networking technologies have not been widely adopted and further developed by major digital library initiatives and projects. Yet semantic technologies offer a new level of flexibility, interoperability, and relationships for digital repositories. Kruk and McDaniel present semantic web-related aspects of current digital library activities, and introduce their functionality; they show examples ranging from general architectural descriptions to detailed usages of specific ontologies, and thus stimulate the awareness of researchers, engineers, and potential users of those technologies. Their presentation is completed by chapters on existing prototype systems such as JeromeDL, BRICKS, and Greenstone, as well as a look into the possible future of semantic digital libraries. This book is aimed at researchers and graduate students in areas like digital libraries, the semantic web, social networks, and information retrieval. This audience will benefit from detailed descriptions of both today's possibilities and also the shortcomings of applying semantic web technologies to large digital repositories of often unstructured data.

Abstract

The authors, hoping to stimulate interest in XML (Extensible Markup Language) and explain its value to the library community, offer a fine introduction to the topic. The opening chapter defines XML as "a system for electronically tagging or marking up documents in order to label, organize, and categorize their content" and then goes on to describe its origins and fundamental building blocks. Subsequent chapters address related technologies, schema development, XML-based tools, and current and future library uses. The authors argue persuasively for increased XML use, emphasizing its advantages over HTML in flexibility, interoperability, extensibility, and internationalization. Information is detailed, deftly written, and supported by numerous examples. Readers without a technological bent may find the text daunting, but their perseverance will be richly rewarded. Particularly recommended for webmasters and those working in library information systems and technical services.

Ein besonders interessanter Aufsatz widmet sich der Frage, wie Bibliotheken ihre Web-Angebote (hier: vor allem die Seiten zu digitalisierten Werken) so optimieren können, dass sie von Google und anderen Suchmaschinen optimal indexiert werden können. Dies wird leicht verständlich erklärt und dürfte für viele Bibliotheken, deren entsprechende Websites noch suboptimal gestaltet sind, eine gute Hilfestellung sein. Auch sehr praktisch orientiert ist der letzte Beitrag des Bandes, der verschiedene Quellen vorstellt, die sich mit aktuellen Entwicklungen bei Google (bzw. bei Suchmaschinen allgemein) beschäftigen, diese einzeln bewertet und Empfehlungen abgibt, welche man regelmäßig und welche man ab und zu lesen sollte. Die Bedeutung ist hier klar: Wenn Bibliotheken sich mit Google messen (oder darüber hinaus gehen?) möchten, müssen sie die Konkurrenz und ihre aktuellen Produkte kennen. Interessant wäre gewesen, noch den einen oder anderen Beitrag zu Suchprodukten von Bibliotheksseite zu lesen. Wie sollten solche Produkte beschaffen sein, um den Google-Nutzer zu den Bibliotheksangeboten zu führen? Welche Angebote gibt es hier bereits? Wie sehen die Anbieter von OPACs und Bibliothekssystemen die Zukunft der Bibliotheksrecherche? Und auch auf die nach Meinung des Rezensenten zurzeit wohl wichtigste Frage im Google-Kontext wird nicht eingegangen: Wie kann es den Bibliotheken gelingen, ein System (oder Systeme) zu schaffen, das nicht nur versucht, die Stärken der Suchmaschinen zu adaptieren, sondern ihnen einen Schritt voraus zu sein? Diese Kritik soll aber nicht darüber hinwegtäuschen, dass es sich bei dem vorliegenden Werk um eine gut lesbare Zusammenstellung von Aufsätzen handelt, die allen empfohlen werden kann, die sich einen Überblick zur Thematik verschaffen wollen, die Diskussion in den internationalen Fachzeitschriften aber nicht sowieso minutiös verfolgen."
