Query: Age-sensitive bibliographic coupling with an application in the history
  of science   In science mapping, bibliographic coupling (BC) has been a standard tool for
discovering the cognitive structure of research areas, such as constituent
subareas, directions, schools of thought, or paradigms. Modelled as a set of
documents, research areas are often sorted into document clusters via BC
representing a thematic unit each. In this paper we propose an alternative
method called age-sensitive bibliographic coupling: the aim is to enable the
standard method to produce historically valid thematic units, that is, to yield
document clusters that represent the historical development of the thematic
structure of the subject as well. As such, the method is expected to be
especially beneficial for investigations on science dynamics and the history of
science. We apply the method within a bibliometric study in the modern history
of bioscience, addressing the development of a complex, interdisciplinary
discourse called the Species Problem.
