Bradford
The librarian of the Science Museum, London, Samuel C. Bradford, (5),
(6), Appendix C, was concerned with problems of abstracting services. In
the course of his research, he asked E. Lancaster Jones, also of the Science
Library, to study the distribution or scatter of papers in applied geophysics
and lubrication, over various journals. Bradford found that there were a
few very productive journals, a larger number of journals with a moderate
number of papers, and a still larger number of journals with only a few
papers relevant to the specifi c topic. He plotted the running total of papers
as a function of the logarithm of the running total of the corresponding
journals ranked in order of productivity and found a fairly straight line,
apart from the papers produced by the fi rst group of large producers. He
plotted Lancaster Jones' data for applied geophysics and lubrication and
stated several times that the `running total' or `aggregate' of references
Summary :
Bradford found that there were a few very productive journals, a larger number of journals with a moderate number of papers, and a still larger number of journals with only a few papers relevant to the specifi c topic.
