    Abstract
    This article introduces a new concept and technique for information retrieval called 'colinked descriptors'. Borrowed from an analogous idea in bibliometrics - cocited references - colinked descriptors provide a theory and method for identifying search terms that, by hypothesis, will be superior to those entered initially by a searcher. The theory suggests a means of moving automatically from 2 or more initial search terms, to other terms that should be superior in retrieval performance to the 2 original terms. A research project designed to test this colinked descriptor hypothesis is reported. The results suggest that the approach is effective, although methodological problems in testing the idea are reported. Algorithms to generate colinked descriptors can be incorporated easily into system interfaces, front-end or pre-search systems, or help software, in any database that employs a thesaurus. The potential use of colinked descriptors is a strong argument for building richer and more complex thesauri that reflect as many legitimate links among descriptors as possible

    Abstract
    Draws attention to the vast potential of online information databases and to the many new possibilities which advanced search techniques offer those who want to explore databases. Looks at informetrics, an emerging subfield in information science, which is based on the combination of advanced information retrieval and quantitative studies of information flow. Describes 3 studies carried out at the Centre for Information studies at the Royal School of Library and Information Science in Copenhagen, Denmark, to illustrate the scope and nature of informetric analysis

    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
    Reports the preliminary results of an investigation into the effectiveness of colinked descriptors, a new concept and technique suitable for incorporating into the design of interfaces for information retrieval. The idea is borrowed from the analogous idea in bibliometrics-cocited references. Preliminary results suggest that the technique is extremely effective. As a retrieval technique, colinked descriptors can easily be incorporated into information retrieval interfaces, front-end systems, or standalone, pre-search systems

    Abstract
    We use a social network approach to examine how work and friendship ties in a university research group were associated with the kinds of media used for different kind of information exchange. The use of e-mail, unscheduled face-to-face encounters, and scheduled face-to-face meetings predominated for the exchange of 6 kinds of information: receiving work, giving work, collaborative writing, computer programming, sociability and major emotional support. Few pairs used synchronous desktop videoconferencing or the telephone

    Abstract
    Reports on a study which collected a sample of 846 scientific research papers published in 1992 and tests 3 hypotheses on the relationship between research collaboration and interdisciplinarity. Results showed significant differences in degrees of interdisciplinarity among different levels of collaboration and among different disciplines. Collaboration contributed significantly to the degree of interdisciplinarity in some disciplines and not in others. Uses a survey that asked authors about their form of collaboration, channels of communication and use of information. The survey provides some qualitative explanation for the bibliometrics findings. Discusses the perspective of scientist-scientist interaction, scientist-information interaction and information-information interaction

    Abstract
    Reports results of a study to investigate the place and role of citation analysis in selected disciplines in the social sciences, including library and information science. 5 core library and information science periodicals: Journal of documentation; Library quarterly; Journal of the American Society for Information Science; College and research libraries; and the Journal of information science, were studed to determine the percentage of articles devoted to citation analysis and develop an indictive typology to categorize the major foci of research being conducted under the rubric of citation analysis. Similar analysis was conducted for periodicals in other social sciences disciplines. Demonstrates how the rubric can be used to dertermine how citatiion analysis is applied within library and information science and other disciplines. By isolating citation from bibliometrics in general, this work is differentiated from other, previous studies. Analysis of data from a 10 year sample of transdisciplinary social sciences literature suggests that 2 application areas predominate: the validity of citation as an evaluation tool; and impact or performance studies of authors, periodicals, and institutions

    Abstract
    Reports results of a cocitation analysis study from the international retrieval research field from 1987 to 1997. Data was taken from Social SciSearch, via Dialog, and the top 40 authors were submitted to author cocitation analysis to yield the intellectual structure of information retrieval. The resulting multidimensional scaling map revealed: identifiable author groups for information retrieval; location of these groups with respect to each other; extend of centrality and peripherality of authors within groups, proximities of authors within groups and across group boundaries; and the meaning of the axes of the map. Factor analysis was used to reveal the extent of the authors' research areas and statistical routines included: ALSCAL; clustering analysis and factor analysis

    Abstract
    Traces the origin and development of informetrics in the field of library and information science. 'Informatrics' is seen as a generic term to denote studies in which quantitative methods are applied. Discusses various applications of informetrics including citation analysis; impact factor; absolescence and ageing studies; bibliographic coupling; co-citation; and measurement of information such as retrieval performance assessment. Outlines recent developments in informetrics and calls for attention to be paid to the quality of future research in the field to ensure its reliability

    Abstract
    WWW and related information technologies are transforming the distribution of scientific and technical information (STI). We examine 11 recent, functioning digital libraries focusing on the distribution of STI publications, including journal articles, conference papers, and technical reports. We introduce 4 main categories of digital library projects: based on the architecture (distributed vs. centralized) and the contributor (traditional publisher vs. authoring individual / organization). Many digital library prototypes merely automate existing publishing practices or focus solely on the digitization of the publishing practices cycle output, not sampling and capturing elements of the input. Still others do not consider for distribution the large body of 'gray literature'. We address these deficiencies in the current model of STI exchange by suggesting methods for expanding the scope and target of digital libraries by focusing on a greater source of technical publications and using 'buckets', an object-oriented construct for grouping logically related information objects, to include holdings other than technical publications
