Reuse of our collections

The École des Ponts ParisTech digital heritage library, a legacy of Ponts et chaussées, was created using the tools developed by the Bibliothèque Nationale de France (BnF - National Library of France) for its Gallica digital library. Hosted by the BnF, the Ponts et chaussées digital heritage library provides access to digital reproductions of works that have mostly fallen into the public domain. The contents are made available to users in medium definition.
