    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
    The act of referencing another author's work in a scholarly or research paper is usually assumed to signal a direct semantic relationship between the citing and cited work. The present article reports a study that examines this assumption directly. The purpose of the research is to investigate the semantic relationship between citing and cited documents for a sample of document pairs in three journals in library and information science: 'Library journal', 'College and research libraries' and 'Journal of the American Society for Information Science'. A macroanalysis, absed on a comparison of the Library of Congress class numbers assigned citing and cited documents, and a microanalysis, based on a comparison of descriptors assigned citing and cited documents by three indexing and abstracting journals, ERIC, LISA and LiLi, were conducted. Both analyses suggest that the subject similarity among pairs of cited and citing documents is typically very small, supporting a subjective, psychological view of relevance and a trial-and-error, heuristic understanding of the information search and research processes. The results of the study have implications for collection development, for an understanding of psychological relevance, and for the results of doing information retrieval using cited references. Several intriguing methodological questions are raised for future research, including the role of indexing depth, specifity, and quality on the measurement of document similarity

    Abstract
    Explores the relationship between the number of cited references used in a citation search and retrieval effectiveness. Focuses on analysing in terms of information retrieval effectiveness, the overlap among posting sets retrieved by various combinations of cited references. Findings from three case studies show the more cited references used for a citation search, the better the performance, in terms of retrieving more relevant documents, up to a point of diminishing returns. The overall level of overlap among relevant documents sets was found to be low. If only some of the cited references among many candidates are used for a citation search, a significant proportion of relevant documents may be missed. The characteristics of cited references showed that some variables are good indicators to predict relevance to a given question

    Abstract
    Predicting relevance of documents from citations is a common problem for information users. The study addresses the relevance prediction process and most specifically, what is viewed by the subject while using the citations. 2 kinds of protocols were collected while 11 subjects viewed 7 citations each. Eye fixations and eye movements between parts of citations were examined. Verbal reports from subjects during this process were used to explore the process of assessment

    Chances for information to be cited (CC) depend on disciplines and topics because of different publication and referencing practices. However, the developmental rate of knowledge strongly influences CC as well. By a simple model concludes that CC are the greater the faster the publication rate

    Abstract
    In a series of articles, Don Swanson explores the problem of associating two or more literatures that are logically, or substantively, related, but bibliographically noninteractive. He has called these implicit links among published literatures undicovered public knowledge. This article explores the fate of Swanson's ideas, using citation content analysis both to determine which authors have utilized Swanson's ideas and to examine the uses to which they have been put. The results suggest that while Swanson has received significant attention from the library and information science community, his ideas have not been widely cited in biomedical disciplines, and, when cited, only with rhetorically dismissive qualifications that detracts from their facticity. These results are interpreted as a failed instance of interdisciplinarity communication, and several explanations of this failure are discussed

    Abstract
    Provides a synoptic review and history of citation indexes and their evolution into research evaluation tools including a discussion of the use of bibliometric data for evaluating US institutions (academic departments) by the National Research Council (NRC). Covers the origin and uses of periodical impact factors, validation studies of citation analysis, information retrieval and dissemination (current awareness), citation consciousness, historiography and science mapping, Citation Classics, and the history of contemporary science. Illustrates the retrieval of information by cited reference searching, especially as it applies to avoiding duplicated research. Discusses the 15 year cumulative impacts of periodicals and the percentage of uncitedness, the emergence of scientometrics, old boy networks, and citation frequency distributions. Concludes with observations about the future of citation indexing

    Abstract
    Science mapping is discussed in the general context of information visualization. Attempts to construct maps of science using citation data are reviewed, focusing on the use of co-citation clusters. New work is reported on a dataset of about 36.000 documents using simplified methods for ordination, and nesting maps hierarchically. an overall map of the dataset shows the multidisciplinary breadth of the document sample, and submaps allow drilling down the document level. An effort to visualize these data using advanced virtual reality software is described, and the creation of document pathways through the map is seen as a realization of Bush's associative trails

    Abstract
    Citation indexes are based on the principle of authors citing previous articles of relevance. The paper demonstrates the long history of citing for precedent and notes how ISI's citation indexes differ from 'Shephards Citations'. The paper analyses some of the criticisms of citations counting, and some of the uses for which citation analysis has been employed. The paper also examines the idea of the development of an Acknowledgement Index, and concludes such an index is unlikely to be commercially viable. The paper describes a citation study of Eugene Garfield, and concludes that he may be the most heavily cited information scientist, that he is a heavy self-citer, and that the reasons why other authors cite Garfield are different from the reasons why he cites himself. The paper concludes that citation studies remain a valid methgod of analysis of individuals', institutions', or journals' impact, but need to be used with caution and in conjunction with other measures
