Over the course of the Middle Ages and the first Renaissance, what was called the ‘Low Countries’ (BeNeLux, Northern France, Northern-Western Rhine Regions) developed an original written culture. The essential part of what has been preserved of this important heritage has fortunately survived in the libraries and manuscript collections of our regions. Over the last few years, important survey and recovery projects have been started. However, not all the heritage collections have been identified or explored, especially in the private and ecclesiastical libraries. Moreover, not all the pre-modern sources useful for the study of this written heritage have yet been identified, surveyed or edited. To facilitate these scholarly activities, we must call on information technologies and particularly on digital humanities for inventory, research, preservation and enhancement of this heritage. Relevant technologies include managing metadata, digitisation, electronic editions, data mining, virtual libraries and virtual digital museology or digitally restoring medieval books. However, all these initiatives have not yet necessarily been surveyed, and they are still not all accessible from a central point of information. Moreover, many manuscripts and the relevant sources that document their history are still poorly known to scholars working in this field. It therefore seems timely and opportune to make an assessment of the initiatives and to establish a research community around the written heritage of the historical Low Countries and the application of digital humanities to this field. An ‘observatory of written heritage’, comparable to Biblissima and in close collaboration with this pioneering French portal in the field, would be a good approach to creating a synergy between keepers of the historical collections, expert librarians, academic teachers and written heritage conservators.
