    Abstract
    There are many advantages for Digital Libraries in indexing with classifications or thesauri, but some current disincentive in the lack of flexible retrieval tools that deal with compound descriptors. This demonstration of a research prototype illustrates a matching function for compound descriptors, or multi-concept subject headings, that does not rely on exact matching but incorporates term expansion via thesaurus semantic relationships to produce ranked results that take account of missing and partially matching terms. The matching function is based on a measure of semantic closeness between terms.The work is part of the EPSRC funded FACET project in collaboration with the UK National Museum of Science and Industry (NMSI) which includes the National Railway Museum. An export of NMSI's Collections Database is used as the dataset for the research. The J. Paul Getty Trust's Art and Architecture Thesaurus (AAT) is the main thesaurus in the project. The AAT is a widely used thesaurus (over 120,000 terms). Descriptors are organised in 7 facets representing separate conceptual classes of terms.The FACET application is a multi tiered architecture accessing a SQL Server database, with an OLE DB connection. The thesauri are stored as relational tables in the Server's database. However, a key component of the system is a parallel representation of the underlying semantic network as an in-memory structure of thesaurus concepts (corresponding to preferred terms). The structure models the hierarchical and associative interrelationships of thesaurus concepts via weighted poly-hierarchical links. Its primary purpose is real-time semantic expansion of query terms, achieved by a spreading activation semantic closeness algorithm. Queries with associated results are stored persistently using XML format data. A Visual Basic interface combines a thesaurus browser and an initial term search facility that takes into account equivalence relationships. Terms are dragged to a direct manipulation Query Builder which maintains the facet structure.

    Abstract
    From a quantitative and qualitative point of view the ETH Library is offering its users an extensive choice of information services. In this respect all researchers, all scientists and also all students have access to nearly all relevant information. This is one side of the coin. On the other hand, this broad, but also heterogeneous bundle of information sources has disadvantages, which should not be underestimated: The more information services and information channels you have, the more complex is it to find what you want to get for your scientific work. A portal-like integration of all the different information resources is still missing. The vision, the main goal of the project "Knowledge Portal" is, to develop a central access system in terms of a "single-point-of-access" for all electronic information services. This means, that all these sources - from the library's catalogue and the fulltext inhouse applications to external, licensed sources - should be accessible via one central Web service. Although the primary target group for this vision is the science community of the ETH Zurich, the interested public should also be taken into account, for the library has also a nation-wide responsibility.The general idea to launch a complex project like that comes from a survey the library did one and a half years ago. We asked a defined sample of scientists what they expected to get from their library and one constant answer was, that they wanted to have one point of access to all the electronic library services and besides this, the search processes should be as simple as possible. We accepted this demand as an order to develop a "single-point-of-access" to all electronic services the library provides. The presentation gives an overview about the general idea of the project and describes the current status.

    Abstract
    Purpose - System usability and system usefulness are interdependent properties of system interaction, which in combination, determine system satisfaction and usage. Often approached separately, or in the case of digital libraries, often focused upon usability, there is emerging consensus among the research community for their unified treatment and research attention. However, a key challenge is to identify, both respectively and relatively, what to measure and how, compounded by concerns regarding common understanding of usability measures, and associated calls for more valid and complete measures within integrated and comprehensive models. The purpose of this paper is to address this challenge. Design/methodology/approach - Identified key usability and usefulness attributes and associated measures, compiled an integrated measurement framework, identified a suitable methodological approach for application of the framework, and conducted a pilot study on an interactive search system developed by a Health Service as part of their e-library service. Findings - Effectiveness, efficiency, aesthetic appearance, terminology, navigation, and learnability are key attributes of system usability; and relevance, reliability, and currency key attributes of system usefulness. There are shared aspects to several of these attributes, but each is also sufficiently unique to preserve its respective validity. They can be combined as part of a multi-method approach to system evaluation. Research limitations/implications - Pilot study has demonstrated that usability and usefulness can be readily combined, and that questionnaire and observation are valid multi-method approaches, but further research is called for under a variety of conditions, with further combinations of methods, and larger samples. Originality/value - This paper provides an integrated measurement framework, derived from the goal, question, metric paradigm, which provides a relatively comprehensive and representative set of system usability and system usefulness attributes and associated measures, which could be adapted and further refined on a case-by-case basis.

    Abstract
    Funding from the UK Electronic Libraries (eLib) programme and the European Community's Fourth Framework programme assisted the initial emergence of information gateways (e.g., SOSIG, EEVL, OMNI in the UK, and EELS in Sweden). Other gateways have been developed by initiatives co-ordinated by national libraries (such as DutchESS in the Netherlands, and AVEL and EdNA in Australia) and by universities and research funding bodies (e.g., GEM in the US, the Finnish Virtual Library, and the German SSG-FI services). An account of the emergence of subject gateways since the mid-1990s by Dempsey gives an historical perspective -- informed by UK experience in particular -- and also considers the future development of subject gateways in relation to other services. When considering the development and future of gateways, it would be helpful to have a clear definition of the service offered by a so-called 'subject gateway'. Precise definitions of 'information gateways', 'subject gateways' and 'quality controlled subject gateways' have been debated elsewhere. Koch has reviewed definitions and suggested typologies that are useful, not least in showing the differences that exist between broadly similar services. Working definitions that we will use in this article are that a subject gateway provides a search service to high quality Web resources selected from a particular subject area, whereas information gateways have a wider criteria for selection of resources, e.g., a national approach. Inevitably in a rapidly changing international environment different people perceive different emphases in attempts to label services, the significant issue is that users, developers and designers can recognise and benefit from commonalties in approach.

    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.
