    Abstract
    There is a decrease in the incidence of explicit references to a paper over time, hence the assumption that information ages. In a study which attempts to discover whether information really ages it is necessary to include eponyms, anonyms and footnote references. Reports a pilot study which demonstrates that there is an increase over time in the frequency of use of eponyms

    Abstract
    There exists a direct linear relation between journal production and impact factor. The more articles a 'normal' journal publishes, the larger its impact factor. Review journals and translation journals are clear exceptions to this rule. The field of mathematics and chemistry seem to be large scale exceptions

    Abstract
    A bibliometric analysis of 1,456 articles appearing in Indian Library and Information Science journals between 1975 and 1985 revealed that the average rate of citations per article in the field was quite low. Books and journals were identified as the major categories of documents referred to in these articles and both were positively related. It is concluded that the increase in journal citations and rate of citations between 1975 and 1985 indicates that Indian Library and Information Science journals are now publishing a higher number of research-oriented articles in comparison with earlier years.

    Abstract
    The collaborative pattern of all Nordic universities, as well as a few universities in the UK and the Netherlands, is analyzed using institutionally co-authored articles retrieved from Science Citation Index. The study shows that there are no major differences between universities of various size when it comes to the proportion of articles with internal, national, or international co-authorships. There are some country variations, but within each country, the differences among the universities are small, if any. When co-authorships were fractionalized according to the number of times a given university occurs among the addresses of an article, there were still no significant differences between universities of varying size. Since external collaboration, whether it is national or international, accounts for more than half of all articles produced by the universities, one is inclined to conclude that the universities function as a kind of cosmopolitan hotel housing nodes of scientific networks that are becoming increasingly international

    Abstract
    The relative impact of local research units is obtained by dividing the observed number of citations to their publications by the expected number of citations. It is argued that the expected citation rates used in the standard method cannot lead to relevant bibliometric scores for specific research topics. Extracting information about quality of research with the standard method is, therefore almost impossible. The existence of empirical relations between the number of citations and the number of publications for scientific disciplines and for journals, leads to alternative ways to determine relative impact. Hereby, refernce data are taken from within a given research topic. Only observed citation and publication (activity) patterns for research topics are taken into account for calculating bibliometric scores. The new methods are not restricted to ISI-publications. The rsulting bibliometric scores can contain information about the quality of research, and lead to different rankings than those obtained with the standard methods, although the same citation and publication data are used

    Abstract
    Reports a qualitative study of the citing motivations of 12 agricultural economists (faculty and doctoral students), identifying several factors they considered in making citing decisions. Reports citing behaviour derived from a larger empirical, longitudinal study tracing document use during research projects and thus includes behaviour related to decisions both to cite and not to cite. An important finding is the existence of metalevel concerns that influence a decision to cite a document, in addition to situational factors related to its actual use during research

    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
    Describes a method for analysing the diffusion of scientific journals, using the Rasch model as the measuring instrument. It is applied to the 10-year distribution of citations to journals of the subject category 'physics' by year of publication of cited articles with data obtained from the SCI Journal Citation Reports of ISI for the year 1994. Diffusion in a scientific field would be regarded as the dissemination of knowledge, channelled through citations that an distributed over different periods of time and propagated by means of scientific journals: here it is considered to be a latent variable defined by a particular set of items (the citations made in different time periods), and the Rasch model is used as an instrument for measuring that variable

    Abstract
    Since the 'Science Citation Index' emerged within the system of scientific communication in 1964, an intense controversy about its character has been raging: in what sense can citation analysis be trusted? This debate can be characterized as the confrontation of different perspectives on science. Discusses the citation representation of science: the way the citation creates a new reality of as well as in the world of science; the main features of this reality; and some implications for science and science policy

    Abstract
    Describes research in which interdisciplinary synthesis and validity analysis (ISVA), a structured learning approach which integrates learning and communication theories, meta analytic evaluation methods, and literature management related technologies, was applied in the context of the 1993-1997 bovine mastitis research literature. The study investigated whether ISVA could facilitate the analysis and synthesis of interdisciplinary knowledge claims and generate projects or research questions
