- Abstract
- This study explores the navigation behaviour of all users of a large web service, Renardus, using web log analysis. Renardus provides integrated searching and browsing access to quality-controlled web resources from major individual subject gateway services. The main navigation feature is subject browsing through the Dewey Decimal Classification (DDC) based on mapping of classes of resources from the distributed gateways to the DDC structure. Among the more surprising results are the hugely dominant share of browsing activities, the good use of browsing support features like the graphical fish-eye overviews, rather long and varied navigation sequences, as well as extensive hierarchical directory-style browsing through the large DDC system.

- Abstract
- The Nordic WAIS/WWW project sponsored by NORDINFO is a joint project between Lund University Library and the National Technological Library of Denmark. It aims to improve the existing networked information discovery and retrieval tools Wide Area Information System (WAIS) and World Wide Web (WWW), and to move towards unifying WWW and WAIS. Details current results focusing on the WAIS side of the project. Describes research into automatic indexing and classification of WAIS sources, development of an orientation tool for WAIS, and development of a WAIS index of WWW resources

- Die verschiedenen Methoden und Instrumente des Navigierens bzw. des Information Retrieval im Internet werden anhand von Beispielen im Überblick vorgestellt. Der Schwerpunkt liegt dabei auf den drei verbreitesten Werkzeugen Gopher, WWW und WAIS. Schwächen un Defizite werden aus der Sicht des Endnutzers analysiert und einige notwendige bzw. wünschenswerte Verbesserungen benannt. Einige Initiativen und Vorschläge zur Weiterentwicklung der Werkzeuge im Netz, teilweise angeregt von einem Blick auf Navigierungs- und Retrievalinstrumente aus Forschung und Entwicklung werden beschrieben

- Abstract
- After a short outline of problems, possibilities and difficulties of systematic information retrieval on the Internet and a description of efforts for development in this area, a specification of the terminology for this report is required. Although the process of retrieval is generally seen as an iterative process of browsing and information retrieval and several important services on the net have taken this fact into consideration, the emphasis of this report lays on the general retrieval tools for the whole of Internet. In order to be able to evaluate the differences, possibilities and restrictions of the different services it is necessary to begin with organizing the existing varieties in a typological/ taxonomical survey. The possibilities and weaknesses will be briefly compared and described for the most important services in the categories robot-based WWW-catalogues of different types, list- or form-based catalogues and simultaneous or collected search services respectively. It will however for different reasons not be possible to rank them in order of "best" services. Still more important are the weaknesses and problems common for all attempts of indexing the Internet. The problems of the quality of the input, the technical performance and the general problem of indexing virtual hypertext are shown to be at least as difficult as the different aspects of harvesting, indexing and information retrieval. Some of the attempts made in the area of further development of retrieval services will be mentioned in relation to descriptions of the contents of documents and standardization efforts. Internet harvesting and indexing technology and retrieval software is thoroughly reviewed. Details about all services and software are listed in analytical forms in Annex 1-3.

- Abstract
- Immer häufiger werden das System 'Internet', die dort genutzten Programmfunktionen und Werkzeuge sowie die damit zugänglichen Informationsangebote in Fachdiskussionen und -veröffentlichungen vorgestellt. Als einführende Hilfsmittel und Ratgeber zur Information über dieses Netzwerk sowie zur eigentlichen Nutzung von Internet sind (neben in elektronischer Form vorliegenden Publikationen) mittlerweile mehrere einführende Printveröffentlichungen in englischer Sprache auf dem Markt. Drei dieser Publikationen werden im vorliegenden Artikel ausführlicher vorgestellt und bewertet. Zum besseren Verständnis des sachlichen Zusammenhangs ist der Rezension ein knapp gefaßter Überblick über die unter dem Begriff 'Internet' zusammengefaßten Funktionen und Informationsangebote vorangestellt.

- Abstract
- Defines metadata, which for librarians means catalogue records for printed publications, and the need for them in document retrieval. The existence of many different sources of metadata had led to a need for simpler metadata schemes and a stadardised exchange format. The 1st Metadata Workshop, held in Dublin, Ohio, reached consensus on a simple resource description record, known as the Dublin core set, with 13 elements, which can serve to unify various models. Lists institutions intending to use it. The 2nd workshop resulted in a proposal for a container record architecture comprising more and different types of metadata than a Dublin core record. The Nordic Metadata project, outlined here, aims to improve the knowledge transfer to the Nordic countries and allow them to paricipate actively in international developments
