Since its creation, 40mcube has been working on the archives of the artistic projects carried out by the art centre. Since 2010, the Archives de la critique d'art have created a 40mcube collection of original documents, while a re-edition work is carried out with the Archives départementales d'Ille-et-Vilaine in the form of one volume per exhibition. The hidden face of the exhibitions and the way they are constructed are thus made visible.

More than 70 volumes containing more than 20,000 documents can be consulted at the art centre and the Departmental Archives of Ille-et-Vilaine, but also online or with the application Inventaire for smartphones.

The volumes are aloso available for consultation at 40mcube during the exhibition period from Wednesday to Saturday from 2pm to 7pm.
