    Abstract
    Bradfordrsquos law of scattering is said to be about subject scattering in information sources. However, in spite of a corpus of writings about the meaning of the word ldquosubjectrdquo and equivalent terms such as ldquoaboutnessrdquo or ldquotopicalityrdquo, the meaning of ldquosubjectrdquo has never been explicitly addressed in relation to Bradfordrsquos law. This paper introduces a distinction between Lexical scattering, Semantic scattering, and Subject scattering. Neither Bradford himself nor any follower has explicitly considered the differences between these three and the implications for the practical applications of Bradfordrsquos law. Traditionally, Bradfordrsquos law has been seen as a neutral and objective tool for the selection of the most central information sources in a field. However, it is hard to find actual reports that describe how Bradfordrsquos law has been applied in practical library and information services. Theoretical as well as historical evidence suggest that the selection of journals based on Bradford-distributions tend to favorite dominant theories and views while suppressing views other than the mainstream at a given time.

    Abstract
    Purpose - The purpose of this research is to examine the practical potentials of Bradford's law in relation to core-journal identification. Design/methodology/approach - Literature studies and empirical tests (Bradford analyses). Findings - Literature studies reveal that the concept of "subject" has never been explicitly addressed in relation to Bradford's law. The results of two empirical tests (Bradford analyses) demonstrate that different operationalizations of the concept of "subject" produce quite different lists of core-journals. Further, an empirical test reveals that Bradford analyses function discriminatorily against minority views. Practical implications - Bradford analysis can no longer be regarded as an objective and neutral method. The received view on Bradford's law needs to be revised. Originality/value - The paper questions one of the old dogmas of the field.
