A new form of document coupling, co-citation, is defined as the frequency with which two documents are cited together. Clusters of co-cited papers provide a new way to study the specialty structure of science. They may provide a new approach to indexing and to the creation of SDI profiles.

Investigates the relationship between information science and the social sciences through a co-citation cluster analysis of a three-year cumulation of the Social Sciences Citation Index. The internal structure of information science clusters is discussed, as well as external linkages to fields of social science. Thirteen references are listed. (BK)

Describes the overall statistical properties of the citation network in science using a new data representation of the citation links within the ISI (Institute for Scientific Information) database. Longitudinal coupling is introduced, which depends on documents which act both as cited and citing items, and bibliographic and cocitation coupling are…

Presents a methodology for creating pathways through the scientific literature following strong cocitation links. A path is described starting in economics and ending in astrophysics, traversing 331 documents. Attention is given to where the path crosses disciplinary boundaries and how analogy can be used to model the thought processes involved in…

Applies a method for generating synopses of scientific fields to a co-citation cluster in field of cancer virology and describes the resulting specialty narrative. Implications of procedure for the cognitive processes involved in reviewing a field are discussed. Appended are lists of highly cited and citing papers. (35 references) (EJS)
