Open access has become a significant part of scientific communication. With regards to dissemination of scientific production, the green road, i.e. self-archiving of scientific work in an open access repository, is often considered as the choice for developing countries because of lower investment and operational costs. This paper will provide a review of relevant literature on the topic, followed by a short overview of open repositories in sub-Saharan African countries, a region facing serious political, economic and social challenges. The main section will present a project for the digitizing of PhD theses of two universities in Togo, and we will then discuss questions and problems related to the specific conditions of the project, in order to contribute to the understanding of the dynamics and rich diversity of the open access movement. Is there an option for sustainable development of open access in these countries? The future will show whether open access contributes to reducing the digital divide between sub-Saharan Africa and other countries or whether it will instead consolidate this divide.
