Abstract

Millions of dollars have been invested into the development of digital libraries. There are many unanswered questions regarding their evaluation, in particular, from users' perspectives. This study intends to investigate users' use, their criteria and their evaluation of the two selected digital libraries. Nineteen subjects were recruited to participate in the study. They were instructed to keep a diary for their use of the two digital libraries, rate the importance of digital library evaluation criteria, and evaluate the two digital libraries by applying their perceived important criteria. The results show patterns of users' use of digital libraries, their perceived important evaluation criteria, and the positive and negative aspects of digital libraries. Finally, the relationships between perceived importance of digital library evaluation criteria and actual evaluation of digital libraries and the relationships between use of digital libraries and evaluation of digital libraries as well as users' preference, experience and knowledge structure on digital library evaluation are further discussed.

Abstract

Digital libraries have become commodity in the current world of Internet. More and more information is produced, and more and more non-digital information is being rendered available. The new, more user friendly, community-oriented technologies used throughout the Internet are raising the bar of expectations. Digital libraries cannot stand still with their technologies; if not for the sake of handling rapidly growing amount and diversity of information, they must provide for better user experience matching and overgrowing standards set by the industry. The next generation of digital libraries combine technological solutions, such as P2P, SOA, or Grid, with recent research on semantics and social networks. These solutions are put into practice to answer a variety of requirements imposed on digital libraries.

Abstract

Digital Libraries currently face the challenge of integrating many different types of research information (e.g. publications, primary data, expert's profiles, institutional profiles, project information etc.) according to their scientific users' needs. To date no general, integrated model for knowledge organization and retrieval in Digital Libraries exists. This causes the problem of structural and semantic heterogeneity due to the wide range of metadata standards, indexing vocabularies and indexing approaches used for different types of information. The research presented in this paper focuses on areas in which activities are being undertaken in the field of Digital Libraries in order to treat semantic interoperability problems. We present a model for the integrated retrieval of factual and textual data which combines multiple approaches to semantic interoperability und sets them into context. Embedded in the research cycle, traditional content indexing methods for publications meet the newer, but rarely used ontology-based approaches which seem to be better suited for representing complex information like the one contained in survey data. The benefits of our model are (1) easy re-use of available knowledge organisation systems and (2) reduced efforts for domain modelling with ontologies.

Abstract

The Digital Public Library of America brings together the riches of America's libraries, archives, and museums, and makes them freely available to the world. In order to do this, DPLA has had to build elements of the national digital platform to connect to those institutions and to serve their digitized materials to audiences. In this article, we detail the construction of two critical elements of our work: the decentralized national network of "hubs," which operate in states across the country; and a version of the Hydra repository software that is tailored to the needs of our community. This technology and the organizations that make use of it serve as the foundation of the future of DPLA and other projects that seek to take advantage of the national digital platform.

Abstract

The concept for the German Digital Libraries Program is imbedded in the Information Infrastructure Program of the German Federal Government for the years 1996-2000 which has been explicated in the Program Paper entitled "Information as Raw Material for Innovation".3 The Program Paper was published 1996 by the Federal Ministry for Education, Research, and Technology. The actual grants program "Global Info" was initiated by the Information and Communication Commission of the Joint Learned Societies to further technological advancement in enabling all researchers in Germany direct access to literature, research results, and other relevant information. This Commission was founded by four of the learned societies in 1995, and it has sponsored a series of workshops to increase awareness of leading edge technology and innovations in accessing electronic information sources. Now, nine of the leading research-level learned societies -- often those with umbrella responsibilities for other learned societies in their field -- are members of the Information and Communication Commission and represent the mathematicians, physicists, computer scientists, chemists, educational researchers, sociologists, psychologists, biologists and information technologists in the German Association of Engineers. (The German professional librarian societies are not members, as such, of this Commission, but are represented through delegates from libraries in the learned societies and in the future, hopefully, also by the German Association of Documentalists or through the cooperation between the documentalist and librarian professional societies.) The Federal Ministry earmarked 60 Million German Marks for projects within the framework of the German Digital Libraries Program in two phases over the next six years. The scope for the German Digital Libraries Program was announced in a press release in April 1997,4 and the first call for preliminary projects and expressions of interest in participation ended in July 1997. The Consortium members were suggested by the Information and Communication Commission of the Learned Societies (IuK Kommission), by key scientific research funding agencies in the German government, and by the publishers themselves. The first official meeting of the participants took place on December 1, 1997, at the Deutsche Bibliothek, located in the renowned center of German book trade, Frankfurt, thus documenting the active role and participation of libraries and publishers. In contrast to the Digital Libraries Project of the National Science Foundation in the United States, the German Digital Libraries project is based on furthering cooperation with universities, scientific publishing houses (including various international publishers), book dealers, and special subject information centers, as well as academic and research libraries. The goals of the German Digital Libraries Project are to achieve: 1) efficient access to world wide information; 2) directly from the scientist's desktop; 3) while providing the organization for and stimulating fundamental structural changes in the information and communication process of the scientific community.

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

European digital libraries have existed in diverse forms and with quite different functions, priorities, and aims. However, there are some common features of European-based initiatives that are relevant to non-European communities. There are now many more challenges and changes than ever before, and the development rate of new digital libraries is ever accelerating. Delivering educational, cultural, and research resources-especially from major scientific and cultural organizations-has become a core mission of these organizations. Using these resources they will be able to investigate, educate, and elucidate, in order to promote and disseminate and to preserve civilization. Extremely important in conceptualizing the digital environment priorities in Europe was its cultural heritage and the feeling that these rich resources should be open to Europe and the global community. In this book we focus on European digitized heritage and digital culture, and its potential in the digital age. We specifically look at the EU and its approaches to digitization and digital culture, problems detected, and achievements reached, all with an emphasis on digital cultural heritage. We seek to report on important documents that were prepared on digitization; copyright and related documents; research and education in the digital libraries field under the auspices of the EU; some other European and national initiatives; and funded projects. The aim of this book is to discuss the development of digital libraries in the European context by presenting, primarily to non-European communities interested in digital libraries, the phenomena, initiatives, and developments that dominated in Europe. We describe the main projects and their outcomes, and shine a light on the number of challenges that have been inspiring new approaches, cooperative efforts, and the use of research methodology at different stages of the digital libraries development. The specific goals are reflected in the structure of the book, which can be conceived as a guide to several main topics and sub-topics. However, the author?s scope is far from being comprehensive, since the field of digital libraries is very complex and digital libraries for cultural heritage is even moreso.

Rez.: ZfBB 52(2005) H.1, S.52-53 (N. Lossau: "Service-Gedanke Digitale Bibliotheken gehören heute bereits zum selbstverständlichen Vokabular von Bibliothekaren und es gibt wohl kaum einen Internetauftritt von Bibliotheken, der nicht eine Digitale Bibliothek beinhaltet. Fast ebenso vielfältig wie die Vorkommen sind auch die Ausprägungen und Definitionen von Digitalen Bibliotheken, weshalb man mit einer Mischung aus Interesse und Skepsis das vorliegende Buch in die Hand nimmt. »The ultimate digital library«, ein ambitionierter Titel, vom Autor und der American Library Association, in deren Reihe die Publikation erschienen ist, wohl nicht zuletzt aus Marketinggründen wohlbedacht gewählt, suggeriert dem Leser, dass hier die vollendete, perfekte Form einer Digitalen Bibliothek beschrieben wird, die sich seit den goer Jahren mit rasantem Tempo entwickelt hat. Es dauert eine ganze Weile, bis der Leser auf die Definition von Pace stößt, die sich als roter Faden durch sein Werk zieht: »The digital library - a comprehensive definition will not be attempted here - encompasses not only collections in digital form, but digital services that continue to define the library as a place.« (S.73) Pace konzentriert sich auf den ServiceAspekt von Digitalen Bibliotheken und zielt damit auf eine Entwicklung ab, die in der Tat als zukunftsweisend für Bibliotheken und Digitale Bibliotheken zu gelten hat. Zu lange haben Bibliotheken sich schwerpunktmäßig auf die digitalen Sammlungen und ihre Produktion (durch Digitalisierung) oder Kauf und Lizenzierung konzentriert, wie Pace zu Recht an der gleichen Stelle beklagt. Die Zukunft mussfür Bibliotheken in der Entwicklung und Bereitstellung von digitalen Services liegen, die den Endnutzern einen echten Mehrwert zu bieten haben. Darin liegt sein Verständnis einer ultimativen Digitalen Bibliothek begründet, ohne dass er die Definition ausführlicher thematisiert. Pace räumt in diesem Zusammenhang auch mit einem Mythos auf, der die Digitalen Bibliotheken lediglich als »Hilfsdienste« einer traditionellen Bibliothek betrachtet. Wesentlich sympathischer und realistischer erscheint dem Leser die folgende Charakterisierung des Verhältnisses: »The digital-traditional relationship is symbiotic, not parasitic: digital tools, services, and expertise exist to enhance the services and collections of libraries, not necessarily to replace them.« (S. 73) Kooperation mit SoftwareAnbietern Der inhaltliche Leitgedanke der digitalen Services ist auch eine ideale Basis für eine weitere Botschaft von Pace, die er mit seinem Buch vermitteln möchte: Bibliothekare und Anbietervon BibliotheksSoftware müssen bei der Entwicklung dieser Services eng zusammenarbeiten. Glaubt man dem Vorwort, dann stellt das Verhältnis von »libraries and vendors« [Bibliotheken und Anbietern] die Ausgangsthematik für die Publikation dar, wie sie von der American Library Association bei Pace in Auftrag gegeben wurde. Dieserverfügt offensichtlich über den geeigneten Erfahrungshintergrund, um eine solche Beschreibung abzuliefern. Nach seinem Studiumsabschluss als M.S.L.S. begann er seine berufliche Laufbahn zunächst für mehr als drei Jahre bei der Firma für Software zur Bibliotheksautomatisierung, Innovative Interfaces,woer unteranderem als Spezialist zur Produktintegration von z.B. WebPAC,Advanced Keyword Search arbeitete. Heute ist Pace »Head of Systems« an den North Carolina State University Libraries (Raleigh, N.C.) und ständiger Kolumnist in dem Magazin Computers in Libraries.
