WebBradford’s 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 “subject” and equivalent terms such as “aboutness” or “topicality”, the meaning of “subject” has never been explicitly addressed in relation to Bradford’s law.

WebBradford's Law of Scattering One year after Zipf first published his law, Bradford [9] described his law of scattering as follows: suppose one takes a set of journals and ranks them in order of the number of articles they carry in a specific discipline. Then if one creates a core of journals basic to the discipline, composed, say, of j journals,
