The purpose of this paper is to identify the specialties in library and information science, using the technique of co-citation analysis. The co-citation analysis assumes that the more often two documents are cited together, the closer the relationship between them. The raw data consists of co-citation counts drawn from the Social Sciences Citation Index, 1966–1970 and 1983.
This paper discusses the intellectual structure of a scientific specialty using Kuhn’s paradigm theory. In this discussion, the specialty is considered a set of paradigm-sharing communities. In this perspective the co-cited authors and the co-cited papers are regarded as the research frontiers in the specialty and the work undertaken by the member specialists.
During the period 1966–1970, four specialties are identified; (1) Scientific information and citation study, (2) Information retrieval, (3) Information dissemination, (4) The specialty of several subjects, for example “the future of the library.”
In 1983, five specialties are identified; (1) Citation study and social studies of science, (2) Information retrieval, (3) The relationship between computers and communication, (4) The evaluation of the library, (5) User study.
