The examination of the notion of science from a sociological perspective has begun to transform the attitudes to science traditionally upheld by historians and philosophers.

An analytical scheme that differentiates among the various types of cognitive and social functions of citations is used as the basis for an analysis of the results of a questionnaire designed to probe the citing behavior of a group of scientists who had cited one of four papers originating from a single biochemical laboratory. Even when papers fall within a relatively well-defined research area and are based on research conducted within a single lab, groups of scientists to which a given (...) paper is of relevance can have quite distinct internal structures. We argue that the scientists'subjective reasons for citing a given work do not correspond with the actual argumentative uses of cited articles in citing texts. Scientists appear to regard the papers they cite as having a rather generalized significance even if in their citations they refer to very specific claims made in the original texts. The consequences of these findings for a theory of citation and for the use of citations in science studies are discussed. (shrink)
