    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
    Within informetry publication and citation analyses stand out. The former are defined as quantitative studies of the content of the bibliographic fields, e.g. authors, in a defined document collection, the latter deal with the documents' literature lists and can be citations fron or to a document. Gives examples of how the RANK command in DIALOG can be used to count information units in phrase indexed fields enabling ranked lists of publications to be produced. DIALOG is best for analysing citations 'from'. A citation analysis 'to' is used for research evaluation, although it is agreed that it can only supplement, not supplant peer review. The Danish Library School's Centre for Informetric Studies researches online analysis and other other informetric questions
