The school library has a unique history in Quebec. Since the puo lication of the Parent Commission report in the 1960s, the many publications and reports that have followed have made obser-vations, proposals, and recommendations to maximize its devel-opment and use. Although it is often defined in theory and has been given an important role in the school landscape, it seems difficult to develop it to its full potential and to support its didac-tic exploitation by teachers. This article first presents the edu-cational, scientific, and social contexts in which the school library develops and then presents the desired connection between librar y and didacti c realities i n order t o position the school library at the centre of teaching and learning situations and thus, at the centre of the didactic system.
