This is the 40th issue of the Docomomo Journal. I remember that in September 2002, when I started my chairmanship, the publication of the Journal seemed a most challenging responsibility. Our aim was to publish a series of six issues, which at the time seemed a considerable accomplishment. In six years we have been able to double that number. This March issue is the best demonstration of Docomomo's growing significance considering both the relevance of the themes it addresses, and its value as a mediator between chapters and public institutions. The table of contents exemplifies at best the Journal's dual character.
