Cellule Math. Doc 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.

NUMDAM Digitisation of Ancient Mathematics Documents NUMérisation de Documents Anciens Mathématiques A digitisation program supported by and Ministère de la Recherche, managed by the Cellule Math. Doc. 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 page @ 600 dpi. • OCR (non-corrected @99, 9%, mathematical formulae and images excluded). • Multi-page files for logical units (TIFF, PDF + hidden text, Dj. Vu). • End-of-article bibliographies treated (corrected OCR @ 99, 99% + markup 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 : ü Prefer standard and easily convertible formats, as sources of future processing if necessary (TIFF, XML), not be tied to a proprietary system. ü Archive high quality images, which should allow to regenerate the text (formula OCR, structure recognition).

NUMDAM Phase I Journals Cornell July 25, 2002 NUMDAM

NUMDAM Phase I: Chronology • Spring 2003. — End of the industrial phase of NUMDAM Phase I, public access to articles via the web. • Autumn 2002. — Start of NUMDAM Phase II. Dealing with © issues continued. • August 2002. — First 50, 000 pages delivered by vendor. • Feb. - May 2002. — Setting-up production chain (vendor) and quality control (Cellule Math. Doc). Dealing with © issues. • Dec. 2001. — Choice of vendor validated by CNRS. • Nov. 2000 - Oct. 2001. — Cataloguing and checking database. • Oct. 2000 - May 2001. — Writing up schedule of conditions/vendor. • July 2000. — 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–Bn. F, 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.
