The Editors in Chief and the Publishers are pleased to announce a recent cooperation between The European Physical Journal (EPJ) and the HAL (Hyper Article on Line) system set-up by the French CNRS. This is a scientific archive system, providing also a direct interface to the LANL (Los Alamos National Laboratory) preprint server.

Our agreement allows authors to upload files containing scientific articles in the HAL database and eventually submit the same files to The European Physical Journal. While the HAL interface offers a free availability online of the documents, these documents do not benefit from a scientific evaluation by peers until they are submitted to a journal. Technically, submission to EPJ from HAL is very simple. After registering in the HAL database, a button invites you to submit in EPJ as well. Presently, there is no way for authors to specify the relevant fields of expertise. The Editorial Office will then manage the distribution of the submissions among the EPJ's sections.
