Past issues of L'Enseignement Mathématique, the official organ of ICMI since the Commission was established in 1908, can be freely accessed online — except for those having appeared in the five most recent years.
The Swiss Digital Mathematics Library (SwissDML) page, hosted on the website of the Swiss Mathematical Society, provides an access to the digitised versions of all the articles in L'Enseignement Mathématique available via the SEALS portal (Swiss Electronic Academic Library Service).
The digitisation process is accompanied by an OCR system (Optical Character Recognition), making possible a fulltext search in the digitised articles. Moreover it is possible to browse the articles on screen, or to download them in pdf format.
