The project consists in making research works visible, and in energizing are search milieu. A lot of research has been carried out in Europe in the field or social work. However, these research works have not been centralized in any European country and/or at a European level. They are scattered in different production sites. In addition, they cannot be identified as such for they are often listed as sociology, social policy, pedagogy, law, etc. work. To recognize the social work nature of these productions requires questioning multiple sources with key words. A researcher wishing to have access to them has no means of obtaining these writings unless he/she devotes a research project to this very task. Thus, stocking research is impossible to accomplish, and the construction of research subjects has to be carried out continuously.
