Abstract : Within a context of evolution and the rapid integration of digitization in university publishing, the fields of the humanities and social sciences, and in particular those of textbooks, do not appear to have found a satisfactory distribution model. In this article, we shall attempt to explain in what measure this sector is different from other areas of university publishing and what hypotheses can be put forward for its future development. Having suggested a carving up of the university publishing market, we would like to place it briefly in an international context. On the basis of this finding, we will present the hypothesis of aggregation: why this should be required, why it does not yet exist and which needs it will respond to. We shall conclude by summarizing these points which we believe are key to the development of a digital university offer in France for the humanities and social sciences.
