This paper investigates the context in which a special library of academic standards could contribute to the work of Secondary Education teachers towards the strengthening of their students’ information skills as a preparation for their smoother transition to University-Level research environment. We describe the collaboration of the scientific library of Eugenides Foundation with two different nearby public schools, for the creation of a project on astronomy. Concerning our research methods, we followed the model of action research, as we needed active participation and dynamic reflection of the learners during the learning process. Despite the various limitations, the outcomes of the whole effort were very positive and led us to the conclusion that close collaboration between high school teachers and the librarians even of an Off-Site library can build on students’ low level information skills in order to reach a high level learning experience.
