    Abstract
    Describes a simple method for developing a list of core serials in a particular subject field by analysing article citations in electronic indexes. The Simple Index Method overcomes the difficulties in building a core list for serials in interdisciplinary fields by using multiple indexes which cover various aspects of the subject. This method permits the collection development librarian to develop a core list when standard bibliographies or specific indexing and abstracting tools are lacking and to tailor that list to the needs of the local situation

    Abstract
    States that it can be shown that claims of a lack of theories of citation are also indicative of a great need for a theory which links science dynamics and measurement. There is a wide gap between qualitative (science dynamics) and quantitative (measurement) approaches. To link them, proposes the use of the citation system, that potentially bridges a gap between measurement and epistemology, by applying system theory to the publication system

    Abstract
    Zipf's law was used to qualify all the key words of documents in a data set. This qualification was used to build a graphical representation of the resulting indicator in each document. The graphical resolution leads to a document dispatch in a 3 dimensional space. This graphical representation was used as an information retrieval tool without using any keyword. The presentation of a case study is available on the WWW. The graph is drawn in VRML allowing a dynamic picture which is linked to a database management system (FreeWAIS)

    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
    A formula for the ranking of scientists based on diachronous citation counts is proposed. The paper generalises the fact that the citation generation potential (CGP) is not the same for all papers, it differs from paper to paper, and also to a certain extent depends on the subject domain of the papers. The method of ranking proposed in no way replaces peer review. It merely acts as an aid for peers to help them arrive at a better judgement.

    Abstract
    Addresses the problem of evaluation of research work both by objective characterization, accessible to proof, and by adequate characterization, referring to the content and cognitive level of the work under investigation. A short discussion of established methods by science indicators as well as by peer review compiles merits and shortcomings of these methods. A short review refers to a few approaches towards the development of criteria for an improved assessment and characterization of research work and their shortcomings are discussed. Notably for the evaluation of medium or low range quality no reliable method is available. Therefore a systematic compilation of criteria which covers the full range of excellence to failure with respect to scientific quality is developed and a comprehensive list of criteris is presented which should provide a basis for objective and adequate characterization of publications

Presents the SciViz system as one particular implementation of this framework

    Abstract
    Investigates the claim that the 'information society' constitutes a new paradigm and describes the use of online bibliometrics to investigate this claim. Judges by its bibliometric behaviour, it is not yet possible to say with any certainty that the 'information society' has achieved paradigmatic status

    Abstract
    Analyses 6 indicators of the Science Citation Index Journals Citation Reports over a 19 year period: number of total citations, number of citations to the previous 2 years, number of source items, impact factor, immediacy index and cited half life. Proposes a box plot method to aggregate the values of each indicator so as to obtain at a glance portrayals of the JCR population from 1974 to 1993. This 'rereading' of the JCR, which presents the JCR product differently, makes it possible to shed new light on the large sub population of journals not at the top of the rankings

    Abstract
    There are numerous international and national programmes to encourage collaboration. However, little is known about the way in which collaboration changes the impact of a research publication. Explores hoe the impact (average citations per paper) varies with different types of collaboration. A calibrated bibliometric model is derived that demonstrates that collaborating with an author from the home institution or another domestic institution increases the average impact by about 0,75 citations while collaborating with an author from a foreign institution increases the impact by about 1.6 citations

    Abstract
    Examines how several commonly measured properties of subject literatures vary as an important factor in the compilation of subject collections (the amount which a document 'says' about a subject) is varied. This document property has been expressed in formal terms and given a simple measure for the one subject examined, the research topic of Bradford's law of scattering. It is found that lowering the level of subject aboutness required for admission to a collection produces a large increase in the size of the collection obtained, and an appreciable change in some size related properties

    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
