The Hic et nunc, computatis! research notebook aims to provide the research community with a space for exchange and information dedicated to medieval accounting (12th-16th century). Its aim will be to centralise a variety of information on current events in this field of historical research (colloquia, seminars, thesis defences, research projects, etc.). In addition, it will be equipped with a nominative and bibliographical directory, thus centralising the scattered references of the work of junior and senior researchers. The research notebook will be managed by a scientific council, one of whose missions will be to periodically organise exchanges on a specific subject.
