The study that Mr. Jean-Claude Simon BIYOKO Mabua proposes to the scientific community has its raison d'être. It should be widely disseminated in teaching and research circles that devote little time and almost no credit to the evaluation of scientific activities of researchers. In other countries, there are laboratories and research centres dedicated to this kind of activity.It is welcome to raise interest in the Congolese scientific community in general and IFASIC in particular. It draws the attention of researchers that IFASIC has not remained on the sidelines of this quantitative approach of researchers' activities by bringing to the knowledge of the world the individual works of IFASIC members. By producing this directory, this tool will first help researchers to easily find scientific books that are online produced by the IFASIC community.Secondly, it lists the number of publications by scientist and finally the fields of publications of the members of the IFASIC scientific community.
