    Abstract
    Reports recent experiences with the publishing, via the Internet and WWW of ISI's biweekly newspaper, The Scientist; which was originally mounted on the NSFnet. Compares the use of the Internet for SDI by comparing Web searches via AltaVista with similar searches on CD-ROM. Predicts that future current awareness services and SDI services will be linked to electronic periodicals in electronic libraries. Concludes with a note on cited reference searching, a variation on the theme of hypertext searching, with particular reference to SCI and Web crawlers

    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
    In spite of numerous studies of citation behaviour and the wide recognition by journal editors of the need to acknowledge intellectual debts, authors and referees need explicit reminders as to when formal refrences or acknowledgements are appropriate. Notes a 3 year experiment involving graduate students which demonstrated the varying perceptions of the need for documentation off terminology, ideas and methods. Suggests a tentative tutorial for journal editors that should be modified in each scholarly context

    Abstract
    Theories of citation are as elusive as theories of information science, which have been debated for decade. Gives an overview of some of these theories, and as a basis for discussion offers the term citationology as the theory and practice of citation, including its derivative disciplines citation analysis and bibliometrics
