    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.
