General terms of use

Numdam is a digital library, containing metadata and full text files of scientific articles. Using the service involves approval of the rules of good conduct which are listed below.

Access to the database containing the bibliographical references of all the articles of all the participating journals is totally free via the search and browse functions. The database itself is the property of Cellule Mathdoc. However metadata are available under licence CC0. Numdam’s metadata are thus dedicated to the public domain. Numdam’s OAI-PMH server can be used for systematic download of metadata in various schemas.

The files containing the full text of articles are downloadable individually by users for research or educational purpose. It is forbidden to download a substantial volume of articles in order to assemble an entire volume of the paper edition or an author or subject based collection. It is forbidden to modify any content available on the Numdam site. In particular, the copyright mention cannot be separated from the attached data, either during copying, transmission or printing of these data.

An important part of the files containing the full texts of articles are dedicated to the public domain. Another part of the articles digitised by the Numdam program remain the property of the authors and the journal. However all journals have a moving-wall policy.
