In recent volumes ofArchival Science writers have pointed out a postmodernistic approach as fruitful for research in archival science. This means that archival research should take full consideration of the societal context in which archives are produced and used. In this article the author pleads for the need to develop scientific methods in archival science as a whole from this postmodernistic approach. So far the debate on archival science has not taken appropriate consideration of the development of scientific methods of our science. In order to establish the necessary basis for an analysis of the scientific methods of the discipline it is necessary to specify the different areas and subareas of archival science. In this analysis it is vital to be precise about the kind of methods that are applicable to each area.
