The Numdam website (Numérisation de documents anciens mathématiques) offers open access to the metadata and articles published in French mathematical journals. For each journal title, all volumes published up to 2000 have been digitised. To date, 560 000 digitised pages and 27 000 articles are available. Articles are available online after a period of time called a moving wall. During this period (generally 5 years), they are available to journal subscribers only. To see which journals are available click on Collections where you will also see the time span covered.
