A scholarly research in European medieval studies can be only founded on the knowldege and the consultation of the actual sources, which until the XIII century are for the most part in Latin. In this field of studies many digital archives have been growing in last years, which collect medieval Latin texts and documents, and perform different kinds of search on them. A free cross-consultation of such databases could very much help the development of the studies, by giving a unique or at least a main reference for quotations and queries about words, names of persons and places, and concepts across the times and the countries. A first meeting of the responsibles and the operators of those archives can take stock of the actual situation by expounding the different features of every data-base, and will become an occasion to design a project for making the medieval Latin archives interact and develop.
