    Abstract
    'Quality-controlled subject gateways' are Internet services which apply a rich set of quality measures to support systematic resource discovery. Considerable manual effort is used to secure a selection of resources which meet quality criteria and to display a rich description of these resources with standards-based metadata. Regular checking and updating ensure good collection management. A main goal is to provide a high quality of subject access through indexing resources using controlled vocabularies and by offering a deep classification structure for advanced searching and browsing. This article provides an initial empirical overview of existing services of this kind, their approaches and technologies, based on proposed working definitions and typologies of subject gateways

    Abstract
    The Iter Project ("iter" means "path" or "journey" in Latin) is an internationally supported non-profit research project created with the objective of providing electronic access to all kinds and formats of materials that relate to the Middle Ages and Renaissance (400-1700) and that were published between 1700 and the present. Knowledge representation and organization decisions for the Project were influenced by its potential international clientele of scholarly users, and these decisions illustrate the importance and efficacy of collaboration between specialized users and information professionals. The paper outlines the scholarly principles and information goals of the Project and describes in detail the methodology developed to provide reliable and consistent knowledge representation and organization for one component of the Project, the Iter Bibliography. Examples of fully catalogued records for the Iter Bibliography are included.

    Abstract
    Reports a preliminary analysis of organizational schemes applied by academic libraries worldwide to arrange their electronic resources an their Web-based information gateways. The unsystematic sample consists of 41 academic libraries in 10 countries representing 4 languages, Chinese, English, German, and Spanish. The study reveals a widely accepted practice in applying 6 simplistic methods to organizing online information: by resource type, alphabetical by title, alphabetical by subject (mostly discipline and genre), by vendor/publisher, by broad classification, and random. In addition, it notes a marked difference between libraries in the English-speaking world and those in other countries in that the former present significantly more systematic characteristics.

    Rez. in Mitt. VÖB 57(2004) H.2, S.71-73 (J. Pauser):"Bei der hier zu besprechenden Arbeit handelt es sich um die Ende 2003 erfolgte Drucklegung einer juristischen Dissertation an der Universität Wien. Die Autorin zielt darauf ab, "Grundlagen, Entstehung, verschiedene Ansätze und Entwicklungstendenzen desjuristischen Information Retrieval aufzuzeigen [...], um schließlich die Qualität der wichtigsten österreichischen Rechtsdatenbanken anhand der gewonnenen Erkenntnisse messen zu können". Das gewählte Thema ist spannend und wohl für jeden Informationswissenschaftler und praktischen Juristen von Relevanz. Elektronische Datenbanken mit Rechtsinformation, seien sie nun online oder offline, revolutionieren seit geraumer Zeit die juristische Arbeit nicht nur in Österreich. Das Recherchieren mittels dieser neuen "Werkzeuge" gehört bereits standardmäßig zur Grundausbildung eines jedes Juristen. Die Kenntnis der umfassenden Möglichkeiten dieser neuen juristischen Informationsquellen beeinflusst massiv die Qualität und vor allem Schnelligkeit des juristischen Arbeitens. Vor diesem Hintergrund ist es immens wichtig, dass die juristischen Datenbanken den Bedürfnissen der Nutzer möglichst zweckmäßig entgegenkommen. Doris Liebwald definiert im ersten Teil ihrer Arbeit den Begriff "Information Retrieval" als "Repräsentation, Speicherung und Organisation von Informationen und der Zugriff auf Informationen" und versucht anschließend Bewertungskriterien für Rechtsdatenbanken aufzustellen. Hinsichtlich der Daten (Gesetze, Gerichtsentscheidungen, juristische Literatur) fordert sie "Vollständigkeit", "Aktualität" und "Authentizität"; in technischer Sicht ergeben sich "Inhaltserschließung", "Suchfunktionen/-möglichkeiten", sowie die "Benutzerfreundlichkeit der Systemoberfläche" etwa durch einfache Bedienbarkeit, Verständlichkeit, Anreicherung durch Hilfefunktionen usw. als Bewertungskriterien, Schließlich sind aus praktisch-ökonomischer Sicht noch "Kosten" und der "Support" aufgenommen.
    Der Hauptteil der Studie umfasst nun fragebogenartig strukturierte Angaben zu insgesamt 18 österreichischen Rechtsinformationsdatenbanken und zwar: Das große - aber wohl nicht zu verhindern gewesene - Manko dieses Abschnittes ist nun, dass er den Stand von Frühjahr/Sommer 2002 wiedergibt und damit zum größten Teil nicht mehr aktuell ist, denn auf dem Rechtsinformationsmarkt ergaben sich in Ietzter Zeit eine Vielzahl an Änderungen durch Verlags- und Produktverschränkungen, technische Neuerungen und Neugestaltung vieler online-Datenbanken. Der Dokumentationsteil hat damit heute fast nur mehr rechtshistorischen Wert. Beispiele: Die "Arbeitsrecht CD-Rom" wurde bereits vom Markt genommen. - "jusline-pro" dürfte auch nicht mehr existieren, zumindest erscheint im Netz an dem angegebenen URL nun schon seit geraumer Zeit ein Hin weis darauf, dass das System "momentan" (sic) nicht zur Verfügung steht. - "Orac Online" und "ARD Online" wurden mittlerweile verändert und zusammengeführt. - Der Parlamentsserver (http://www.parlinkom.gv.at) hat einen umfassenden grafischen Relaunch hinter sich gebracht, der sich leider nicht zum Vorteil des Nutzers auswirkt. Zugegeben, das alte Design wirkte billig, veraltet und unschön, aber man fand schnell und zügig die "Stenographischen Protokolle" und die "Materialien". Das neue Design fällt trotzdem weit hinter die praktikablen Standards anderer europäischer Parlamente zurück. Leider wurde hier eine Chance vertan. Die Angesprochenen rechtsrelevanten Inhalte sind zwar weiterhin und in großer Menge vorhanden, doch erfordert die Suche nun ein gewisses Maß an archivarischem Fleiß. Viele Nutzer, die sich zuvor sehr leicht getan haben, hatten nach der Umstellung der Website massive Probleme. Vielleicht hätte man hier sinnvollerweise die Publikums-Website mit den allgemeinen Daten zum Parlamentvon der Datenbank-Website mit den gesetzgebungsrelevanten Daten trennen und letztere benutzerfreundlicher aufbereiten sollen. - Die RDB hat nun ein neues Content-Portal eröffnet, das mit dem alten, hier dargestellten, kaum mehr etwas gemeinsam hat. - Im RIS werden seit Anfang 2004 die Bundesgesetzblätter authentisch kundgemacht. - Die Steuerdatenbank ist nunmehr mit der SWK-Online vereinigt. Das mag hier als Hinweis genügen. Ein kurzes zehnseitiges "Ergebnis" beschließt die Studie. Hierwurde die Chance vertan, die dargestellten Datenbanken umfassender zu vergleichen und Unterschiede, Vorteile, Nutzungsmöglichkeiten, Praxisvor- und -nach teile usw. etwa mittels eines standardisierten Tests herauszuarbeiten. Die Arbeit wird ihren Wert vor allem darin entfalten, Datenbankanbieter zu einer Verbesserung ihrer Datenbanken anzuregen. Der Hinweis, dass "die dem User zur Verfügung gestellten Hilfefunktionen und Informationen als untauglich oder unzureichend zu bewerten sind" (S. 191), sollten sich wirklich alle Datenbankanbieter auf diesem Gebiet zu Herzen nehmen."

    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

    Content
    "Wer im Jahr 2003 in seinen Lieblingsthemen detailliert informiert sein möchte, klappert täglich Dutzende von News-Sites und Webmagazinen ab. Ein Unterfangen, das mitunter recht mühselig sein kann: Neben, über und unter den gewünschten Nachrichten quälen sich bei jedem Aufruf Menüleisten, Banner und Grafiken durch die Leitung, und oft genug wurde die Seite seit seinem vergangenen Besuch nicht einmal aktualisiert. RSS-Clients, auch Feedreader genannt, könnten künftig Surfern die zeitaufwendige Handarbeit abnehmen. Das Prinzip ist denkbar einfach: Die Betreiber von Webangeboten stellen - neben den HTML-Seiten, die übliche Browser benötigen - einen so genannten Newsfeed zur Verfügung. Genau genommen handelt es sich dabei um nichts Weiteres. als eine speziell kodierte Textdatei mit berschriften, Zusammenfassungen und Textausschnitten der jeweils jüngsten Meldungen. Der Feedreader dreht in regelmäßigen Abständen seine Runden, holt diese Dateien und - wieder daheim - präsentiert die enthaltenen Informationen übersichtlich lesbar. Erst ein Klick auf eine Überschrift lädt den entsprechenden Originalartikel schließlich in den Webbrowser. Statt sich der Reizüberflutung auf Dutzenden, unterschiedlich gestylten Websites auszusetzen, genügt so ein Blick auf die systematisch geordneten Texteinträge im Fenster des Feedreaders, um zu entscheiden, welche Beiträge einer genaueren Betrachtung würdig sind und welche nicht. Diese Sammel-und-Zeige-Programme gibt es mittlerweile in vielen Geschmacksrichtungen und für nahezu jedes Betriebssystem (siehe "Feedreade"). Der Haken: Die Betreiber der Webangebote müssen den Dienst unterstützen und die nötigen RSS-Dateien zur Verfügung stellen. Da sich die meisten News-Magazine allerdings mit Bannerwerbung finanzieren, standen ihre Herausgeber dieser Verbreitung ihrer Texte bisher skeptisch gegenüber. Doch langsam denken viele um: Immerhin kann das System Besucher anlocken. Und nicht irgendwelche. Die Leser sind ausgesprochen interessiert und motiviert, da sie sich explizit für ein bestimmtes Angebot entschieden haben - und nicht zufällig oder unter Zeitdruck durch die einzelnen Seiten stolpern. Spätestens seit mit Yahoo einer der großen Anbieter seine aktuellen Meldungen als Newsfeed verbreitet, darf man davon ausgehen, dass etliche Mitbewerber folgen werden. So könnte die praktische Technologie in absehbarer Zeit zum nützlichen Alltagswerkzeug werden. Bis das soweit ist, übernehmen spezialisierte Dienste den Job des Mittlers zwischen den Welten: Unter NewsIsFree.com kann sich jeder User seine individuelle Auswahl an RSSFeeds zusammenstellen. Sollte das betreffende Internet-Angebot die Technik noch nicht unterstützen, wird einfach kurzerhand der notwendige Feed extern generiert - ob es dem Betreiber nun passt oder nicht. Der Service ist in der Basis-Version kostenlos. RSS steht für "Rich Site Summary". Doch zuletzt werden die drei Buchstaben häufiger als Akronym für "Really Simple Syndication" eingesetzt. Die Idee geht zurück auf das Jahr 1999, als das mittlerweile beinahe verblichene Unternehmen Netscape mit Hilfe dieses Verfahrens die Popularität seines Portals MyNetscape.com erhöhen wollte. Der Durchbruch kam mit der Verbreitung der Weblogs. Angeregt durch die Integration des RSS-Standards in das beliebte Blog-Tool Radio Userland, übernahmen die Hersteller anderer Publishing-Systeme schnell diese Strategie, und heute kommt kaum noch ein Online-Journal ohne eigenen Newsfeed aus - erkennbar am kleinen XML-Button auf der Startseite.

    Abstract
    The classic problem within the information quality (IQ) research and practice community has been the problem of defining IQ. It has been found repeatedly that IQ is context sensitive and cannot be described, measured, and assured with a single model. There is a need for empirical case studies of IQ work in different systems to develop a systematic knowledge that can then inform and guide the construction of context-specific IQ models. This article analyzes the organization of IQ assurance work in a large-scale, open, collaborative encyclopedia - Wikipedia. What is special about Wikipedia as a resource is that the quality discussions and processes are strongly connected to the data itself and are accessible to the general public. This openness makes it particularly easy for researchers to study a particular kind of collaborative work that is highly distributed and that has a particularly substantial focus, not just on error detection but also on error correction. We believe that the study of those evolving debates and processes and of the IQ assurance model as a whole has useful implications for the improvement of quality in other more conventional databases.

    Abstract
    Der vollständige Projektname von Renardus lautet "Academic Subject Gateway Service Europe". Renardus wird von der Europäischen Union im 5. Rahmenprogramm mit dem Schwerpunktthema "Information Society Technologies" im zweiten Thematischen Programm "Benutzerfreundliche Informationsgesellschaft" ('Promoting a User-friendly Information Society') gefördert. Die Projektlaufzeit ist von Januar 2000 bis Juni 2002. Insgesamt zwölf Partner (Principal und Assistant Contractors) aus Finnland, Dänemark, Schweden, Großbritannien, den Niederlanden, Frankreich und Deutschland beteiligen sich an diesem Projekt. Die Europäische Union unterstützt das Projekt mit 1,7 Mio. EURO, die Gesamtkosten belaufen sich inklusive der Eigenbeteiligungen der Partner auf 2,3 Mio. EURO. Das Ziel des Projektes Renardus ist es, über eine Schnittstelle Zugriff auf verteilte Sammlungen von "High Quality" Internet Ressourcen in Europa zu ermöglichen. Diese Schnittstelle wird über den Renardus Broker realisiert, der das "Cross-Searchen" und "Cross-Browsen" über verteilte "Quality-Controlled Subject Gateways" ermöglicht. Ein weiteres Ziel von Renardus ist es, Möglichkeiten von "metadata sharing" zu evaluieren und in kleinen Experimenten zwischen z. B. Subject Gateways und Nationalbibliothek zu testen bzw. zu realisieren

    Abstract
    Die Zentralstelle für Agrardokumentation und -information (ZADI) entwickelt derzeit eine Multi-Host-Suchmaschine (MHS) zur simultanen Suche in mehreren, an unterschiedlichen Orten befindlichen Datenbanken. Erste Anwendungen der Technologie befinden sich in einem Prototypen des Bundesinformationssystems Genetische Ressourcen (BIG) sowie in einer Multi-Host-Literatursuchmaschine der Food and Agriculture Organization (FAO) der Vereinten Nationen im Test. Der Beitrag stellt Notwendigkeit und Anforderungen dar und erörtert zur Problemlösung eingesetzte Methoden. Die implementierte Funktionalität wird anhand des für die FAO entwickelten Prototypen zur Literatursuche erläutert

    Abstract
    More than 100 U.S. governmental agencies offer links through FedStats, a centralized Web site that facilitates access to statistical tables, reports, and agencies. This and similar large collections need appropriate interfaces to guide the general public to easily and successfully find information they seek. This paper summarizes the results of 3 empirical studies of alternate organization concepts of the FedStats Topics Web page. Each study had 15 participants. The evolution from 645 alphabetically organized links, to 549 categorically organized links, to 215 categorically organized links tied to portal pages produced a steady rise in successful task completion from 15.6 to 24.4 to 42.2%. User satisfaction also increased. We make recommendations based an these data and our observations of users.
