    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 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
    The key political and strategic issues which needs to be addressed for the future development of the Australian subject gateways are: continued quality of content creation, integration of access to print and electronic resources, archiving and persistent identification, sustainability of services and service integration. These issues will be more effectively tackled internationally, and the Australian subject gateways are keen to work with international collaborators to achieve a mutually beneficial outcome

    Abstract
    Evaluates the performance of 8 major Internet search engines in answering 21 real reference questions and 5 made up subject questions. Reports on the retrieval and relevancy ranking abilities of the search engines. Concludes that the search engines did not produce good results for the reference questions unlike for the subject questions. The best engines are identified by type of questions, with Infoseek best for the subject questions, and OpenText best for refrence questions

    Abstract
    Eine ganze Anzahl von Bibliotheken in Europa befaßt sich mit der Entwicklung von Internet Subject Gateways - einer Serviceleistung, die den Nutzern helfen soll, qualitativ hochwertige Internetquellen zu finden. Subject Gateways wie SOSIG (The Social Science Information Gateway) sind bereits seit einigen Jahren im Internet verfügbar und stellen eine Alternative zu Internet-Suchmaschinen wie AltaVista und Verzeichnissen wie Yahoo dar. Bezeichnenderweise stützen sich Subject Gateways auf die Fertigkeiten, Verfahrensweisen und Standards der internationalen Bibliothekswelt und wenden diese auf Informationen aus dem Internet an. Dieses Referat will daher betonen, daß Bibliothekare/innen idealerweise eine vorherrschende Rolle im Aufbau von Suchservices für Internetquellen spielen und daß Information Gateways eine Möglichkeit dafür darstellen. Es wird einige der Subject Gateway-Initiativen in Europa umreißen und die Werkzeuge und Technologien beschreiben, die vom Projekt DESIRE entwickelt wurden, um die Entwicklung neuer Gateways in anderen Ländern zu unterstützen. Es wird auch erörtert, wie IMesh, eine Gruppe für Gateways aus der ganzen Welt eine internationale Strategie für Gateways anstrebt und versucht, Standards zur Umsetzung dieses Projekts zu entwickeln

    Abstract
    Project SSG-FI at SUB Göttingen provides special subject gateways to international high quality Internet resources for scientific users. Internet sites are selected by subject specialists and described using an extension of qualified Dublin Core metadata. A basic evaluation is added. These descriptions are freely available and can be searched and browsed. These are now subject gateways for 3 subject ares: earth sciences (GeoGuide); mathematics (MathGuide); and Anglo-American culture (split into HistoryGuide and AnglistikGuide). Together they receive about 3.300 'hard' requests per day, thus reaching over 1 million requests per year. The project SSG-FI behind these guides is open to collaboration. Institutions and private persons wishing to contribute can notify the SSG-FI team or send full data sets. Regular contributors can request registration with the project to access the database via the Internet and create and edit records

    Abstract
    Information subject gateways provide targeted discovery services for their users, giving access to Web resources selected according to quality and subject coverage criteria. Information gateways recognise that they must collaborate on a wide range of issues relating to content to ensure continued success. This report is informed by discussion of content activities at the 1999 Imesh Workshop. The author considers the implications for subject based gateways of co-operation regarding coverage policy, creation of metadata, and provision of searching and browsing across services. Other possibilities for co-operation include working more closely with information providers, and diclosure of information in joint metadata registries

    Abstract
    Das gezielte Suchen im Internet findet in erster Linie mit Hilfe der Suchmaschinen statt. Daneben gibt es aber bereits eine Fülle von strukturierten Informationsangeboten, aufbereiteten Listen und Sammelstellen, die als Clearinghouse, Subject Gateway, Subject Tree oder Resource Pages bezeichnet werden. Solche intellektuell erstellten Übersichten geben in der Regel bereits Hinweise zu Inhalt und fachlichem Niveau der Quelle. Da die Art und Weise der Aufbereitung bei den Sammelstellen sehr unterschiedlich funktioniert, ist die Kenntnis ihrer Erschließungskriterien für ein erfolgreiches Retrieval unverzichtbar

    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
    Eine ganze Anzahl von Bibliotheken in Europa befaßt sich mit der Entwicklung von Internet Subject Gateways - einer Serviceleistung, die den Nutzern helfen soll, qualitativ hochwertige Internetquellen zu finden. Subject Gateways wie SOSIG (The Social Science Information Gateway) sind bereits seit einigen Jahren im Internet verfügbar und stellen eine Alternative zu Internet-Suchmaschinen wie AltaVista und Verzeichnissen wie Yahoo dar. Bezeichnenderweise stützen sich Subject Gateways auf die Fertigkeiten, Verfahrensweisen und Standards der internationalen Bibliothekswelt und wenden diese auf Informationen aus dem Internet an. Dieses Referat will daher betonen, daß Bibliothekare/innen idealerweise eine vorherrschende Rolle im Aufbau von Suchservices für Internetquellen spielen und daß Information Gateways eine Möglichkeit dafür darstellen. Es wird einige der Subject Gateway-Initiativen in Europa umreißen und die Werkzeuge und Technologien beschreiben, die vom Projekt DESIRE entwickelt wurden, um die Entwicklung neuer Gateways in anderen Ländern zu unterstützen. Es wird auch erörtert, wie IMesh, eine Gruppe für Gateways aus der ganzen Welt eine internationale Strategie für Gateways anstrebt und versucht, Standards zur Umsetzung dieses Projekts zu entwickeln

    Abstract
    This paper analyses the development of the knowledge structures provided as aids to users in searching the Internet. Specific focus is given to web directories, thesauri and gateways and portals. The paper assumes that users need to be able to access information in two ways - to locate information on a subject directly in response to a search term and to be able to browse so as to familiarize themselves with a domain or to refine a request. Emphasis is to the browsing aspect. Background and development are addressed. Structures are analyzed, problems are identified, and future directions discussed.

    Abstract
    Four focus groups were held with young Web users (10 to 13 years of age) to explore design criteria for Web portals. The focus group participants commented upon four existing portals designed with young users in mind: Ask Jeeves for Kids, KidsClick, Lycos Zone, and Yahooligans! This article reports their first impressions on using these portals, their likes and dislikes, and their suggestions for improvements. Design criteria for children's Web portals are elaborated based upon these comments under four headings: portal goals, visual design, information architecture, and personalization. An ideal portal should cater for both educational and entertainment needs, use attractive screen designs based especially on effective use of color, graphics, and animation, provide both keyword search facilities and browsable subject categories, and allow individual user personalization in areas such as color and graphics

    Abstract
    Surfing the World Wide Web used to be cool, dude, real cool. But things have gotten hot - so hot that finding something useful an the Web is no longer cool. It is suffocating Web searchers in the smoke and debris of mountain-sized lists of hits, decisions about which search engines they should use, whether they will get lost in the dizzying maze of a subject directory, use the right syntax for the search engine at hand, enter keywords that are likely to retrieve hits an the topics they have in mind, or enlist a browser that has sufficient functionality to display the most promising hits. When it comes to Web searching, in a few short years we have gone from the cool image of surfing the Web into the frying pan of searching the Web. We can turn down the heat by rethinking what Web searchers are doing and introduce some order into the chaos. Web search strategies that are tool-based-oriented to specific Web searching tools such as search en gines, subject directories, and meta search engines-have been widely promoted, and these strategies are just not working. It is time to dissect what Web searching tools expect from searchers and adjust our search strategies to these new tools. This discussion offers Web searchers help in the form of search strategies that are based an strategies that librarians have been using for a long time to search commercial information retrieval systems like Dialog, NEXIS, Wilsonline, FirstSearch, and Data-Star.
