The Executive Committee of ICMI is pleased to announce the opening of the ICMI Digital Library.  This project aims at eventually making available freely online all the documents related to ICMI and its activities, including material such as the ICMI Study volumes or the Proceedings of the International Congresses on Mathematical Education.

It is highly appropriate that on the occasion of the inauguration of the ICMI Digital Library, a major book is thus made available to the ICMI community: the Proceedings of the symposium jointly organised in 2000 by ICMI and the University of Geneva to celebrate the centennial of the journal L'Enseignement Mathématique, the official organ of ICMI since its inception in 1908. 

The ICMI EC is grateful to the editors of L'EM for generously granting permission to make this book available via the ICMI website.
