- Abstract
- Seeks to describe the social networks, or invisible colleges, that make up a scientific speciality, in terms of mathematically precise sets generated by document citations and accessible through the Social Science Citation Index. The document and author sets that encompass a scientific specialty are the basis for some interdependent citation matrices. The method of construction of these sets and matrices is illustrated through an application to the literature on invisible colleges
