In science mapping, bibliographic coupling (BC) has been a standard tool fordiscovering the cognitive structure of research areas, such as constituentsubareas, directions, schools of thought, or paradigms. Modelled as a set ofdocuments, research areas are often sorted into document clusters via BCrepresenting a thematic unit each. In this paper we propose an alternativemethod called age-sensitive bibliographic coupling: the aim is to enable thestandard method to produce historically valid thematic units, that is, to yielddocument clusters that represent the historical development of the thematicstructure of the subject as well. As such, the method is expected to beespecially beneficial for investigations on science dynamics and the history ofscience. We apply the method within a bibliometric study in the modern historyof bioscience, addressing the development of a complex, interdisciplinarydiscourse called the Species Problem.
