    Abstract
    ADEPT is a 5-year project whose goals are to develop, deploy, and evaluate inquiry learning capabilities for the Alexandria Digital Library, an extant digital library of primary sources in geography. We interviewed nine geography faculty members who teach undergraduate courses about their information seeking for research and teaching and their use of information resources in teaching. These data were supplemented by interviews with four faculty members from another ADEPT study about the nature of knowledge in geography. Among our key findings are that geography faculty are more likely to encounter useful teaching resources while seeking research resources than vice versa, although the influence goes in both directions. Their greatest information needs are for research data, maps, and images. They desire better searching by concept or theme, in addition to searching by location and place name. They make extensive use of their own research resources in their teaching. Among the implications for functionality and architecture of geographic digital libraries for educational use are that personal digital libraries are essential, because individual faculty members have personalized approaches to selecting, collecting, and organizing teaching resources. Digital library services for research and teaching should include the ability to import content from common office software and to store content in standard formats that can be exported to other applications. Digital library services can facilitate sharing among faculty but cannot overcome barriers such as intellectual property rights, access to proprietary research data, or the desire of individuals to maintain control over their own resources. Faculty use of primary and secondary resources needs to be better understood if we are to design successful digital libraries for research and teaching.

    Abstract
    The current subject gateways have evolved over time when the discipline of Internet resource discovery was in its infancy. This is reflected by the lack of well-established, light-weight, deployable, easy-to-use, standards for metadata and information retrieval. We provide an introduction to the architecture, standards and software solutions in use by subject gateways, and to the issues that must be addressed to support future subject gateways

    Abstract
    NOVAGate is a subject-based information gateway covering electronic resources in the agricultural, veterinary and related fields. The service, which opened in July 1998, is produced by the veterinary and agricultural libraries of the 5 Nordic countries - Denmark, Finland, Iceland, Norway and Sweden - which serve the NOVA University. The gateway covers Nordic and European resources as well as the resources of international organizations, but being planned is a network of subject gateways which will give access to a wide range of international quality resources within the agricultural, veterinary and related fields. The service uses the ROADS software

    Abstract
    The Australian Academic Research Library Information Network (AARLIN) aims to provide seamless access to Australian and international information resources for researchers via their personal computers through a personally customisable portal. The project has funding from the Australian Govemment. AARLIN commenced in the year 2000 with a pilot project and will develop into a fully operational service in Australian universities over the next three years. During the pilot project Ex Libris' Metalib and SFX software have been used to trial the AARLIN portal concept with a group of researchers. The results of a survey of the researchers are presented. It is concluded that the portal has the potential to enhance the work of researchers by improving their success in information searching.

    Abstract
    Through out this book we showed that Semantic Digital Libraries are no longer an abstract concept; we have presented both underlying technologies, examples of semantic digital libraries, and their applications. However, the bright future of this technology only begins, and we expect more and more genuine applications of semantic digital libraries to emerge. In this section we will spotlight on three of, in our opinion, the most promising of applications: semantic museums, eLearning 2.0, and semantic digital libraries in enterprises.

    Abstract
    Purpose - One of the unresolved problems of the global information society is ensuring the long-term accessibility of digital documents. The project kopal tackles this problem head-on: in a three-year project kopal's objective is the practical testing and implementation of a cooperatively created and operated long-term archival system for digital resources. Design/methodology/approach - The system will be implemented in accordance with international standards for long-term archiving and metadata within the Open Archival Information System (OAIS) framework. The project partners, Die Deutsche Bibliothek (DDB), Göttingen State and University Library (SUB Göttingen), IBM Deutschland GmbH and the Gesellschaft für wissenschaftliche Datenverarbeitung mbH Göttingen (GWDG), will establish a cooperatively transferable solution for cultural heritage institutions, as well as for business and industry. Findings - Within the project, the project partners DDB and SUB Göttingen are developing software for the input and access of data, which will be released under an open-source license. Research limitations/implications - Long-term preservation methods and strategies will be discussed in general in the paper. Practical implications - The project will present a stable and reusable platform for additional partners and users, especially for cultural heritage organisations. Originality/value - The solution is based on Digital Information and Archiving System (DIAS), jointly devised by IBM and the National Library of The Netherlands in The Hague, and it will be adapted to the needs of the project with several extensions. Establishing a collaborative solution for long-term preservation is a milestone in the development of systems for the long-term availability of digital objects.

    Abstract
    A preliminary, purposive survey of definitions and current applications of facet analytical theory (FA) is used to develop a framework for the analysis of Websites. This set of guidelines may well serve to highlight commonalities and differences among FA applications an the Web. Rather than identifying FA as the terrain of a particular interest group, the goal is to explore current practices, uncover common misconceptions, extend understanding, and highlight developments that augment the traditional practice of FA and faceted classification (FC).

    Abstract
    Many subject specific portals were built during the last year. Most of these are simple user-interfaces to databases of subject specific information added with several lists of links. This centralised type of portal often looks fine with its consistent facing but is hard to keep up to date and high priced to maintain. Users expect a service be malntained and available 24 hours, 365 days for at least 10 years and this all free of charge. On the one hand, it seams to be impossible to set up a service matching all this demands, an the other hand, many institutions offer information and services which could be parts of a portal, which are maintained frequently and paid by public via these institutions. The idea is, to collect the existing information and present it in a structured and consistent way. This idea matches in an excellent way with the way knowledge is produced in Physics. Physicists work all over the world often an different continents an the same topic, knowing each others work only from their publications, conferences and online-communication. Information in Physics is published in quite different ways, by journal articles, which can be reviewed, sometimes by peer, or pre-prints. Many information is available in non-textual genres like software sources or datasets or mathematical formula. Distributed Portals make use of the existing information an the web. In the early days of the web, the very popular link-lists where a kind of portal, linking to (all) pages with information an the specific topic. Indeed, these link lists had many properties of modern portals, offering information in a structured and selected way. But they did not offer the information under a common layout (desktop) and did not offer user-specific views onto the information. Modern distributed portals combine the advantages of centralised portals (high information structure, common layout, easy navigation through all the information) with the possibilities of distributed portals (up to date information, low budget implementation, good knowledge coverage).

    Abstract
    The strongest tradition of IR systems evaluation has focused on system effectiveness; more recently, there has been a growing interest in evaluation of Interactive IR systems, balancing system and user-oriented evaluation criteria. In this paper we shift the focus to considering how IR systems, and particularly digital libraries, can be evaluated to assess (and improve) their fit with users' broader work activities. Taking this focus, we answer a different set of evaluation questions that reveal more about the design of interfaces, user-system interactions and how systems may be deployed in the information working context. The planning and conduct of such evaluation studies share some features with the established methods for conducting IR evaluation studies, but come with a shift in emphasis; for example, a greater range of ethical considerations may be pertinent. We present the PRET A Rapporter framework for structuring user-centred evaluation studies and illustrate its application to three evaluation studies of digital library systems.

    Abstract
    Do a search on AltaVista for "algebra". What do you get? Nearly 700,000 hits, of which AltaVista will allow you to view only what it determines is the top 200. Major search engines such as AltaVista, Excite, HotBot, Lycos, and the like continue to provide a valuable service, but with the recent growth of the Internet, topic-specific sites that provide some organization to the topic are increasingly important. It the goal of the Mathematics Archives to make it easier for the ordinary user to find useful mathematical information on the Web. The Mathematics Archives (http://archives.math.utk.edu) is a multipurpose site for mathematics on the Internet. The focus is on materials which can be used in mathematics education (primarily at the undergraduate level). Resources available range from shareware and public domain software to electronic proceedings of various conferences, to an extensive collection of annotated links to other mathematical sites. All materials on the Archives are categorized and cross referenced for the convenience of the user. Several search mechanisms are provided. The Harvest search engine is implemented to provide a full text search of most of the pages on the Archives. The software we house and our list of annotated links to mathematical sites are both categorized by subject matter. Each of these collections has a specialized search engine to assist the user in locating desired material. Services at the Mathematics Archives are divided up into five broad topics: * Links organized by Mathematical Topics * Software * Teaching Materials * Other Math Archives Features * Other Links

    Abstract
    Purpose - The purpose of this paper is to report an investigation into the ways in which Canadian digital library collections have incorporated knowledge organization systems into their search interfaces. Design/methodology/approach - A combination of data-gathering techniques was used. These were as follows: a review of the literature related to the application of knowledge organization systems, deep scanning of Canadian governmental and academic institutions web sites on the web, identify and contact researchers in the area of knowledge organization, and identify and contact people in the governmental organizations who are involved in knowledge organization and information management. Findings - A total of 33 digital collections were identified that have made use of some type of knowledge organization system. Thesauri, subject heading lists and classification schemes were the widely used knowledge organization systems in the surveyed Canadian digital library collections. Research limitations/implications - The target population for this research was limited to governmental and academic digital library collections. Practical implications - An evaluation of the knowledge organization systems interfaces showed that searching, browsing and navigation facilities as well as bilingual features call for improvements. Originality/value - This research contributes to the following areas: digital libraries, knowledge organization systems and services and search interface design.

    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
    This chapter describes not so much what digital libraries are but what digital libraries with semantic support could and should be. It discusses the nature of Knowledge Organization Systems (KOS) and how KOS can support digital library users. It projects a vision for designers to make and for users to demand better digital libraries. What is a digital library? The term \Digital Library" (DL) is used to refer to a range of systems, from digital object and metadata repositories, reference-linking systems, archives, and content management systems to complex systems that integrate advanced digital library services and support for research and practice communities. A DL may offer many technology-enabled functions and services that support users, both as information producers and as information users. Many of these functions appear in information systems that would not normally be considered digital libraries, making boundaries even more blurry. Instead of pursuing the hopeless quest of coming up with the definition of digital library, we present a framework that allows a clear and somewhat standardized description of any information system so that users can select the system(s) that best meet their requirements. Section 2 gives a broad outline for more detail see the DELOS DL Reference Model.

    Abstract
    Purpose - The purpose of this article is to introduce the digital libraries of the future, their enabling technologies and their organisational models. Design/methodology/approach - The paper first discusses the requirements for the digital libraries of the future, then presents the DILIGENT infrastructure as a technological response to these requirements and, finally, it discusses the role that libraries can play in the organisational framework envisioned by DILIGENT. Findings - Digital libraries of the future will give access to a large variety of multimedia and multi-type documents created by integrating content from many different heterogeneous sources that range from repositories of text, images, and audio-video, to scientific data archives, and databases. The digital library will provide a seamless environment where the co-operative access, filtering, manipulation, generation, and preservation of these documents will be supported as a continuous cycle. Users of the library will be both consumers and producers of information, either by themselves or in collaborations with other users. Policy ensuring mechanisms will guarantee that the information produced is visible only to those who have the appropriate rights to access it. The realisation of these new digital libraries requires both the provision of a new technology and a change in the role played by the libraries in the information access-production cycle. Practical implications - Digital libraries of the future will be core instruments for serving a large class of applications, especially in the research field. Originality/value - The paper briefly introduces one of the most innovative technologies for digital libraries, and it discusses how it contributes to the realisation of a novel digital libraries scenario.

    Abstract
    Grounded on a strong belief that ontologies enhance the performance of information retrieval systems, there has been an upsurge of interest in ontologies. Its importance is identified in diverse research fields such as knowledge engineering, knowledge representation, qualitative modeling, language engineering, database design, information integration, object-oriented analysis, information retrieval and extraction, knowledge management and agent-based systems design (Guarino, 1998). While the role-played by ontologies, automatically lends a place of legitimacy for these tools, research in this area gains greater significance in the wake of various challenges faced in the contemporary digital environment. With the objective of overcoming various pitfalls associated with current search mechanisms, ontologies are increasingly used for developing efficient information retrieval systems. An indicator of research interest in the area of ontology is the Swoogle, a search engine for Semantic Web documents, terms and data found on the Web (Ding, Li et al, 2004). Given the complex nature of the digital content archived in digital libraries, ontologies can be employed for designing efficient forms of information retrieval in digital libraries. Knowledge representation assumes greater significance due to its crucial role in ontology development. These systems aid in developing intelligent information systems, wherein the notion of intelligence implies the ability of the system to find implicit consequences of its explicitly represented knowledge (Baader and Nutt, 2003). Knowledge representation formalisms such as 'Description Logics' are used to obtain explicit knowledge representation of the subject domain. These representations are developed into ontologies, which are used for developing intelligent information systems. Against this backdrop, the paper examines the use of Description Logics for conceptually modeling a chosen domain, which would be utilized for developing domain ontologies. The knowledge representation languages identified for this purpose are Web Ontology Language (OWL) and KArlsruhe ONtology (KAON) language. Drawing upon the various technical constructs in developing ontology-based information systems, the paper explains the working of the prototypes and also presents a comparative study of the two prototypes.

    Abstract
    This article describes two approaches for searching heterogeneous resources, which are explained as they are used in two corresponding existing systems-RIRS (Resource Integration Retrieval System) and HRUSP (Heterogeneous Resource Union Search Platform). On analyzing the existing systems, a possible framework-the MUSP (Multimetadata-Based Union Search Platform) is presented. Libraries now face a dilemma. On one hand, libraries subscribe to many types of database retrieval systems that are produced by various providers. The libraries build their data and information systems independently. This results in highly heterogeneous and distributed systems at the technical level (e.g., different operating systems and user interfaces) and at the conceptual level (e.g., the same objects are named using different terms). On the other hand, end users want to access all these heterogeneous data via a union interface, without having to know the structure of each information system or the different retrieval methods used by the systems. Libraries must achieve a harmony between information providers and users. In order to bridge the gap between the service providers and the users, it would seem that all source databases would need to be rebuilt according to a uniform data structure and query language, but this seems impossible. Fortunately, however, libraries and information and technology providers are now making an effort to find a middle course that meets the requirements of both data providers and users. They are doing this through resource integration.

    Abstract
    Der Fachinformationsdienst (FID) Pharmazie verfolgt das Ziel, die Informationsinfrastruktur und die Literaturversorgung für die pharmazeutische Hochschulforschung nachhaltig zu verbessern. Das Projekt wird seit dem 1. Januar 2015 von der Deutschen Forschungsgemeinschaft gefördert. Eine Besonderheit stellt die Kooperation zwischen der Universitätsbibliothek Braunschweig und dem Institut für Informationssysteme (IfIS) der TU Braunschweig dar, wodurch aktuelle Forschung auf dem Gebiet der Informatik in die Implementierung innovativer FID-Dienste mündet. Im Zentrum des Projektes steht der nutzerzentrierte Aufbau einer erweiterbaren und personalisierbaren Informationsinfrastruktur. Das vom FID entwickelte Discovery System "PubPharm" zur pharmaziespezifischen Recherche basiert, als Weiterentwicklung des beluga-Systems der SUB Hamburg, auf der Open Source Software VuFind. Als Datengrundlage enthält es u.a. die Medline Daten, erweitert durch Normdaten, die unter anderem die Suche nach chemischen Strukturen erlauben. Gleichzeitig werden vom Institut für Informationssysteme innovative Suchmöglichkeiten basierend auf Narrativer Intelligenz untersucht und perspektivisch in das Retrieval des Discovery Systems eingebunden. Im Rahmen von sog. FID-Lizenzen bietet der FID Pharmazie Wissenschaftlern/innen Volltextzugriff auf pharmazeutische Fachzeitschriften. Bestandteil der Lizenzen ist das Recht zur Langzeitarchivierung. Bei deren technischer Umsetzung kooperiert der FID mit der TIB Hannover. Der FID Pharmazie koppelt seine Aktivitäten eng an die pharmazeutische Fachcommunity: unter anderem begleitet ein Fachbeirat die Entwicklungen. Im Rahmen der Öffentlichkeitsarbeit werden Nutzer/innen umfassend über die Angebote informiert, u.a. in Webcasts und im PubPharm Blog.

    Abstract
    Purpose - The general science portal "vascoda" merges structured, high-quality information collections from more than 40 providers on the basis of search engine technology (FAST) and a concept which treats semantic heterogeneity between different controlled vocabularies. First experiences with the portal show some weaknesses of this approach which come out in most metadata-driven Digital Libraries (DLs) or subject specific portals. The purpose of the paper is to propose models to reduce the semantic complexity in heterogeneous DLs. The aim is to introduce value-added services (treatment of term vagueness and document re-ranking) that gain a certain quality in DLs if they are combined with heterogeneity components established in the project "Competence Center Modeling and Treatment of Semantic Heterogeneity". Design/methodology/approach - Two methods, which are derived from scientometrics and network analysis, will be implemented with the objective to re-rank result sets by the following structural properties: the ranking of the results by core journals (so-called Bradfordizing) and ranking by centrality of authors in co-authorship networks. Findings - The methods, which will be implemented, focus on the query and on the result side of a search and are designed to positively influence each other. Conceptually, they will improve the search quality and guarantee that the most relevant documents in result sets will be ranked higher. Originality/value - The central impact of the paper focuses on the integration of three structural value-adding methods, which aim at reducing the semantic complexity represented in distributed DLs at several stages in the information retrieval process: query construction, search and ranking and re-ranking.

    Abstract
    Digital libraries have become one of the most important Web services for information seeking. One of their main drawbacks is their global approach: In general, there is just one interface for all users. One of the key elements in improving user satisfaction in digital libraries is personalization. When considering personalizing factors, cognitive styles have been proved to be one of the relevant parameters that affect information seeking. This justifies the introduction of cognitive style as one of the parameters of a Web personalized service. Nevertheless, this approach has one major drawback: Each user has to run a time-consuming test that determines his or her cognitive style. In this article, we present a study of how different classification systems can be used to automatically identify the cognitive style of a user using the set of interactions with a digital library. These classification systems can be used to automatically personalize, from a cognitive-style point of view, the interaction of the digital library and each of its users.
