“In this article, I sketch Otlet’s and Kaiser’s ideas about information analysis and compare the types of knowledge organization systems (KOSs) that they constructed on the basis of these ideas. As we shall see, Otlet and Kaiser held very similar views about the possibility – and desirability – of disaggregating documents into information units and organizing the latter into indexed information files. Both men also agreed on the technological means to implement their information-analytic approach.” (Thomas M. Dousa – ASIS&T Bulletin Dec/Jan 2010)
