Led by the library of the French School École nationale des chartes (ENC), ThENC@ is a multi-layered project whose aim is to digitize and upload onto a single online platform academic works, the particularity of which is that these theses written by the School archivists-paleographers are not actually held by the School library. This project addresses the issues of digitization and restoration of documents, constitution of a corpus when the physical documents are not stored in a single place, copyright and open access, metadata work, and creation of a digital library. It shows the important role of libraries in accessing both old and recent academic works online.
