    Abstract
    Reports investigations into the feasibility and reliability of calculating impact factors for web sites, called Web Impact Factors (Web-IF). analyzes a selection of 7 small and medium scale national and 4 large web domains as well as 6 institutional web sites over a series of snapshots taken of the web during a month. Describes the data isolation and calculation methods and discusses the tests. The results thus far demonstrate that Web-IFs are calculable with high confidence for national and sector domains whilst institutional Web-IFs should be approached with caution

    Abstract
    Investigates the possibilities and limitations of online citation analysis. The Dialog online processing tools RANK, MAP and TARGET are used to perform analysis of citations to and from isolated sets of documents as well as to carry out diachrone journal analysis. Discusses the implications of this analysis on the journal impact factors of ISI journals. Suggests that by the combined application of RANK and TARGET, a hitherto overlooked possibility of the online analysis of bibliographic coupling and mapping of scientific fields has been revealed

    Abstract
    Introduces the application of informetric methods to the WWW, called Webometrics. A case study, in which the Danish proportion of the WWW is compared to those of other Nordic countries, presents a workable methods for general informetrc analyses of the WWW. The methodological approach is comparable with common bibliometric analyses of the ISI databases. Among other results the analyses demonstrate that Denmark would seem to fail seriously behind the other Nordic countries with respect to visibility on the Net and compared to its position in scientific databases
