Cornell July 25, 2002 NUMDAM Cellule MathDoc www-mathdoc.ujf-grenoble.fr An institute on Scientific Information & Communication in Mathematics, supported by Centre National de la Recherche Scientifique (CNRS) and Ministère de la Recherche. General mission: documentation issues in mathematics at the national level in France, in cooperation with mathematics libraries and institutes.

Cornell July 25, 2002 NUMDAM NUMDAM: aims Reinforce French mathematical journals (visibility, accessibility, durability). Hand down digitised archives of the French mathematical heritage to future generations and participate in international efforts with the same endeavour. Strive towards making this digitised mathematical heritage freely accessible.

Cornell July 25, 2002 NUMDAM Political choices Database freely accessible on the web. Full text freely accessible after a moving – wall (depending on each serial). Scheduled interoperability between retro-digitized and natively digital collections. National and international co-operations in as far as possible.

Cornell July 25, 2002 NUMDAM Technical choices Scan from first to last 600 dpi. OCR mathematical formulae and images excluded). Multi-page files for logical units (TIFF, PDF + hidden text, DjVu). End-of-article bibliographies treated (corrected 99,99% + mark- up of “ author ”, “ title ”, “ year ” fields) Database: cataloguing data for each article, summary (if present), end- of-article bibliography (if present), hidden OCRed text. Structured data exchange in XML. In as far as possible links to/from JFM, ZM and MR databases. Future enhancements scheduled depending on technology available.

Cornell July 25, 2002 NUMDAM Production choices Use of an external operator for the technical treatments. « In house » study, segmentation, cataloguing, quality control, and display. Quality and durability policy : Prefer standard and easily convertible formats, as sources of future processing if necessary (TIFF, XML), not be tied to a proprietary system. Archive high quality images, which should allow to regenerate the text (formula OCR, structure recognition).

Cornell July 25, 2002 NUMDAM NUMDAM Phase I: Chronology Spring — End of the industrial phase of NUMDAM Phase I, public access to articles via the web. Autumn — Start of NUMDAM Phase II. Dealing with © issues continued. August — First 50,000 pages delivered by vendor. Feb. - May — Setting-up production chain (vendor) and quality control (Cellule MathDoc). Dealing with © issues. Dec — Choice of vendor validated by CNRS. Nov Oct — Cataloguing and checking database. Oct May — Writing up schedule of conditions/vendor. July — Funding by CNRS.

Cornell July 25, 2002 NUMDAM NUMDAM Phase II Take an active part in the Digital Mathematics Library project. Cooperate with other digitisation projects (Gallica–BnF, possibly EMANI digitisation part). Inventory of resources & cooperation with historians and mathematicians to make scientific choices and establish priorities, in order to Digitise all French mathematics journals (Annales de l’Institut Henri Poincaré, Annales de l’Université de Toulouse, Comptes Rendus de l’Académie, Journal de l’École polytechnique,....), and possibly some mathematically important general science journals. Digitise important seminar series (séminaires Bourbaki, Cartan, séminaire de Probabilités de Strasbourg,...). Digitise a substantial set of important monographies.
